Lydecker JA, Gueorguieva R, Grilo CM. Rapid response to behavioral/pharmacological obesity treatments for binge-eating disorder predicts better clinical outcomes. Obesity (Silver Spring) 2025. [PMID: 40265670 DOI: 10.1002/oby.24292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2024] [Revised: 03/03/2025] [Accepted: 03/06/2025] [Indexed: 04/24/2025]
Abstract
OBJECTIVE The objective of this study was to examine rapid response and its prognostic significance in participants with binge-eating disorder (BED) and obesity in a randomized clinical trial testing behavioral and pharmacological obesity treatments for BED. METHODS A total of 136 participants were randomly assigned (balanced 2 × 2 factorial) to 16-week behavioral and/or pharmacological (naltrexone/bupropion) obesity interventions. Masked assessments occurred monthly throughout treatment and at posttreatment. RESULTS Rapid response (≥65% reduction in frequency of binge-eating episodes after 1 month of treatment), observed in 55% (n = 75/136) of participants, was unrelated to baseline sociodemographic and clinical characteristics. Rapid response was more common in behavioral therapy than not and in naltrexone/bupropion than placebo. Rapid response was associated with binge-eating remission. Mixed models revealed that rapid response was associated with greater reductions in binge-eating frequency, eating-disorder psychopathology, percent weight loss, and metabolic variables (total cholesterol, glycated hemoglobin A1c) at posttreatment. Rapid response effects on outcomes did not vary by treatment. CONCLUSIONS In a randomized clinical trial testing behavioral and pharmacological obesity treatments for BED with co-occurring obesity, rapid response was a robust prognostic indicator of binge-eating remission and significantly better behavioral, psychological, and metabolic outcomes. Non-rapid response to behavioral and pharmacological obesity treatments could signal a need to switch to alternative treatments.

Abstract
OBJECTIVE To develop and test the effectiveness of the eBEfree program, a 12-session app-based version of a previously tested psychological intervention (BEfree) that combines psycho-education, self-compassion, mindfulness, and Acceptance and Commitment Therapy to reduce binge-eating symptoms. METHOD Two-hundred participants with recurrent elevated binge-eating symptoms and a higher body weight were enrolled in a remote parallel-group randomized trial, of which 142 completed the initial assessment (70 in the intervention group). The end-of-treatment and follow-up assessments were conducted 12 weeks after the initial assessment and 26 weeks after the end of treatment, respectively. Intention-to-treat (ITT) analyzes were undertaken using frequentist linear mixed models and Bayesian hierarchical models to test the intervention effectiveness. RESULTS 43 (waitlist control) and 29 (intervention) participants completed the end-of-treatment assessment, showing a high attrition rate (51%). ITT analyzes showed the eBEfree program to be associated with a significant reduction in binge eating symptomatology from baseline to end-of-treatment (β = -9.49, ρ < 0.0001, g = -1.17), and from end-of-treatment to 26-weeks follow-up (β = -6.01, ρ = 0.04, g = -1.08). At end-of-treatment, the intervention was also associated with a decrease in body mass index and depression symptomatology, as well as an improvement in dimensions of self-criticism and mindfulness. More than 80% of participants rated the quality of the program as positive and helpful. DISCUSSION This trial suggests potential benefits of the eBEfree program to help individuals manage symptoms of binge-eating more effectively, reduce weight, and improve well-being and mental health. The intervention benefits should be confirmed in future larger trials. PUBLIC SIGNIFICANCE Treating binge-eating (BE) symptoms and associated comorbidities might be challenging for mental health services. Digital and app-based interventions can be a valuable resource to help people manage symptoms and improve well-being and mental health. The current trial suggests the potential benefits of an app-based intervention (eBEfree program) to help people reduce BE symptoms and develop psychological strategies to promote well-being and mental health.

Abstract
BACKGROUND Binge Eating Disorder (BED) is the most prevalent eating disorder, yet it remains under-recognized and insufficiently understood in both healthcare and society. This leads to a lack of appropriate treatment options and challenges of identification within somatic healthcare. Our study aims to elucidate effective treatment approaches for BED by exploring patients' personal understandings of their treatment needs. METHODS We interviewed 6 individuals diagnosed with BED regarding their healthcare experiences and analyzed the data using a modified qualitative method combining thematic and interpretive phenomenological analysis. RESULTS The analysis resulted in three main themes: Lack of understanding, Trapped in body shame and Hope and movement, each with belonging subcategories. These themes narrate a journey from being unrecognized with a psychological issue, feeling immobilized by body shame towards embarking on recovery. Particularly Trapped in body shame links the other main themes representing a barrier and a pivotal point in the recovery process. CONCLUSIONS Our study highlights that shame related to binge eating and body image is pervasive in participants, exacerbated by a healthcare system that often prioritizes weight and lifestyle. Such shame can block treatment access and prolong the disorder. We argue for a paradigm shift in clinical practice towards patient-centered care that prioritizes empathy and holistic support over weight-focused models. Group therapy can be beneficial in reducing shame, if the group composition is carefully considered. Effective BED treatment should involve creating a safe environment for discussing body shame, emphasizing the need to address this issue to improve treatment effectiveness and patient satisfaction.

Abstract
BACKGROUND Eating disorders are complex mental disorders the prevalence of which has continued to increase, particularly since the coronavirus pandemic. Binge Eating Disorder has been newly included as a diagnosis in the Diagnostic and Statistical Manual of Mental disorders 5 (DSM-5) and the International Classification of Diseases 11th revision (ICD-11). AIM OF THE WORK We present a state of the art overview of diagnostic criteria, psychopathology, differential diagnostics, epidemiology, comorbidities, developmental and maintenance factors, treatment and care situation of binge eating disorder. MATERIAL AND METHODS A narrative review is provided. RESULTS Binge eating disorder is characterized by recurrent binge eating with loss of control. It is the most common eating disorder in the general population and is often associated with overweight or obesity. Neurobiological models see changes in the areas of emotion regulation, reward processing and impulse control as etiological contributions to binge eating disorder. Psychotherapy is the treatment of choice for binge eating disorder, which often goes undetected and untreated. A reason for this is the experienced or feared stigmatization, shame and feelings of guilt of those affected. DISCUSSION As the diagnosis of a binge eating disorder influences the choice of treatment and the prognosis of both the eating disorder and a potentially comorbid obesity, active clarification of the eating behavior and a possible eating disorder in the context of motivational interviewing is essential.

Abstract
Family therapy for eating disorders (ED) is well-established and represents the treatment choice for ED in children and adolescents according to guidelines, with cognitive behavior therapy (CBT) as a second line treatment. There is limited knowledge about how these treatments work in routine clinical care. The goal of the present meta-analysis is to investigate the effectiveness of family therapy and CBT for various EDs in children and adolescents when carried out in routine clinical care. Ovid MEDLINE, Embase OVID, and PsycINFO were searched for articles published until December 2023. The outcome of family therapy and CBT, methodological quality, risk of bias, and moderators of treatment outcome were examined and benchmarked by meta-analytically comparing with ED efficacy studies. Forty-four effectiveness studies comprising 3251 family therapy or CBT patients were included. Large to very large within-group effect sizes (ES) were found for ED-psychopathology (0.80) and weight measures for AN (1.64) at post treatment. The attrition rate was 15%. Risk of bias was considerable. Moderate to large ES were found for family therapy and CBT, respectively. The benchmarking analysis showed that effectiveness studies had comparable ESs to efficacy studies (0.80 and 0.84 for the ED-psychopathology at post treatment). The findings support family therapy and CBT for ED in children and adolescents as effective treatments when delivered in routine clinical care, with effects comparable with those found in efficacy studies. The evidence needs to be interpreted with caution because of the risk of bias in a high proportion of studies.PROSPERO [CRD42023441794].

Abstract
We aimed to evaluate the effects of obesity treatment with behavioral therapy (BT) and cognitive behavioral therapy (CBT) interventions compared with multiple comparators and find effective techniques or combinations of techniques in BT and CBT interventions for weight loss. We systematically searched electronic databases and selected randomized controlled trials using CBT or BT intervention for obesity treatment in overweight adults or adults with obesity without psychological symptoms. Both pairwise meta-analysis and network meta-analysis were performed to comprehensively evaluate the comparative effects between interventions. We classified the techniques used in BT and CBT interventions and compared the treatment effects between techniques. Compared with no treatment as a common comparator, CBT was most effective for weight loss, followed by BT, usual care (UC), and minimal care (MC). CBT was a more effective intervention than BT, but the effect of CBT compared to BT was not remarkable in network estimates. The most used BT techniques were feedback and monitoring, and the most used CBT technique was cognitive restructuring. Our results indicated that CBT and BT are effective interventions for weight loss, and that successful weight loss requires more aggressive interventions such as BT or CBT than MC and UC.

Abstract
Mindfulness-based interventions (MBIs) have gained popularity in recent years in treating binge eating. Previous reviews and meta-analyses have found that MBIs demonstrated medium-large to large effects in reducing binge eating. However, as the literature on this topic has been growing rapidly, an updated review on MBIs' effectiveness is much needed. This study is a 10-year update of the Godfrey, Gallo, & Afari (2015) systematic review and meta-analysis of MBIs for binge eating. PubMED, PsycINFO, and Web of Science were searched using keywords including binge eating, overeating, objective bulimic episodes, acceptance and commitment therapy, dialectical behavior therapy, mindfulness, meditation, and mindful eating. Results indicate there has been a large increase in the number of studies testing MBIs for binge eating in the past 10 years with 54 studies meeting inclusion criteria, compared to 19 ten years ago. The majority of the studies yielded large and medium effect sizes. The random effects meta-analysis of between-group effect sizes yielded medium-large effects for MBIs versus non-psychological intervention controls at post-treatment (mean Hedge's g = - 0.65) and follow-up (mean Hedge's g = - 0.71), and negligible effects for MBIs versus active psychological controls at post-treatment (mean Hedge's g = - 0.05) and follow-up (mean Hedge's g = 0.13). Of all MBIs, DBT had the most studies with large effects. More studies examined MBIs that directly targeted binge eating had larger effects than studies with MBIs targeting other health outcomes (with binge eating as a secondary outcome). New studies included in the current review were internationally-conducted, focused more on participants with overweight or obesity, involved more self-help and technology-based components, and had more novel and innovative interventions components. Future MBIs research should conduct more RCTs comparing MBIs with other psychological interventions, conduct meta-analyses to examine the effectiveness of different types of MBIs and intervention targets, and extend follow-up periods.

Abstract
OBJECTIVE Binge-eating disorder (BED) is a prevalent, costly public health problem associated with serious functional impairments and heightened rates of psychiatric and medical comorbidities. Few evidence-based treatments are currently available for BED. We tested the effectiveness of cognitive-behavioral therapy (CBT), lisdexamfetamine (LDX), and combined CBT+LDX, for BED comorbid with obesity. METHODS Randomized controlled trial was conducted March 2019 to September 2023 at a single site. N=141 patients with BED (83.7% women, mean age 43.6, mean BMI 38.6 kg/m2) were randomized to one of three 12-week treatments: CBT (N=47), LDX (N=47), or CBT+LDX (N=47); 87.2% completed independent posttreatment assessments. RESULTS Mixed models revealed binge-eating frequency decreased significantly in all treatments, with CBT+LDX having the largest reduction and significantly outperforming CBT and LDX, which did not differ. Intention-to-treat binge-eating remission rates differed significantly between treatments, with CBT+LDX having the highest remission rate (70.2%) followed by CBT (44.7%) and LDX (40.4%). Mixed models revealed percent weight loss increased significantly throughout treatment with LDX and CBT+LDX but remained unchanged in CBT. LDX and CBT+LDX had significantly greater percent weight loss than CBT starting after one month and through posttreatment. Intention-to-treat rates of attaining ≥5% weight loss differed across treatments, with LDX having the highest (53.2%), followed by CBT+LDX (42.6%) and CBT (4.3%). Analyses revealed significant reductions in eating-disorder psychopathology; CBT+LDX had largest reductions and significantly outperformed CBT and LDX. CONCLUSIONS CBT, LDX, and CBT+LDX showed significant improvements in BED, with a consistent pattern of the combined CBT+LDX being superior to the two individual treatments, which differed little.

Abstract
BACKGROUND Eating disorders during the perinatal period can pose significant risks to both the mother and the baby. Clinical practice guidelines include statements of expected practice intending to improve effectiveness and quality of care within health care services. This systematic review aimed to identify and synthesise current clinical practice guideline recommendations on the assessment, management and treatment of eating disorders during the perinatal period. METHODS Three bibliographic databases and five guideline repository databases were searched alongside the grey literature. Guidelines were screened against eligibility criteria and recommendations for the assessment, management or treatment of eating disorders during the perinatal period were extracted. All included guidelines were assessed for quality using the AGREE-II tool. Recommendations were analysed and summarised using narrative synthesis. RESULTS From the 242 records screened, 17 met inclusion criteria. Guideline quality ranged from three out of seven to seven out of seven. Six overall recommendations were formed from the narrative synthesis of data: 1) Early detection: recognising the signs and symptoms, 2) Assessment and screening: a three-pronged approach, 3) Educating and supporting the mother: the importance of knowledge, 4) Cross-system collaboration, 5) Psychological, pharmacological and medical treatment, and 6) Continued monitoring. CONCLUSION Perinatal eating disorder guideline recommendations were fairly consistent but showed considerable variability in quality and depth of recommendations. Recommendations require further contextualisation, to allow them to be operationalised and implemented within services. The review findings provide an initial framework for health care professionals responsible for supporting women with eating disorders during the perinatal period, and have several implications for policy, service delivery and health outcomes for women and their families.

Abstract
OBJECTIVE The aim of this study was to identify naturally occurring groups of individuals experiencing binge eating (BE) symptoms based on their endorsement of varied functions of BE. METHOD Adults (N = 646) with self-reported BE symptoms were examined using latent profile analysis to identify differentiated profiles based on eight established functions of BE. Profiles were also compared on measures of BE symptoms, eating disorder psychopathology, internal shame, body shame, psychological distress, adverse childhood experiences, and demographic variables. RESULTS A four-profile solution was selected balancing goodness-of-fit and interpretability. Profiles identified were Emotion Avoidance, Classic, Emotion Reactivity, and Complex, with profiles differing primarily on emotion- and trauma-related functions of BE, and varying on all associated characteristics examined, with the Complex profile showing the most adverse associations. DISCUSSION The identification of these distinct profiles suggests that individuals present with differentiated, inter-related patterns or reasons for BE. These clinically relevant profiles may inform binge-eating intervention choice and the targeting of specific maintenance factors within profiles. Further research is needed to examine the clinical utility of these profiles in informing the most suitable psychological treatment for an individual.

Abstract
BACKGROUND Cognitive-behavioral therapy (CBT) is an evidence-supported treatment for adolescents with binge-eating disorder (BED). Executive dysfunctions, which are associated with binge eating and elevated body weight in youth, may undermine CBT outcomes by making it difficult for youth to engage with or adhere to treatment, including recalling and/or implementing intervention strategies in real-world contexts. METHODS We assessed 73 adolescents [82.2% female; Mage = 15.0 ± 2.5 year; M baseline standardized body mass index (zBMI) = 1.9 ± 1.0 kg/m2] with BED at baseline, posttreatment, 6-, 12-, and 24-month follow-up. Linear mixed models examined the effects of baseline executive functioning (EF) on loss of control (LOC) eating and weight change following CBT. Linear and logistic regressions probed associations between EF, attendance, and attrition. RESULTS More impulsive decision-making, as reflected in higher baseline scores on the Iowa Gambling Task, predicted better attendance (β = .07; p = .019) and more frequent LOC eating following treatment (β = .12; p = .017). Lower cognitive flexibility, as reflected in lower baseline T-scores on the Comprehensive Trail Making Test complex sequencing index, predicted higher zBMI following treatment (β = -.03; p = .003). Inhibition, concentration, attention, and parent-reported EF behavior symptoms were not associated with outcome, attendance, or attrition. CONCLUSIONS More impulsive decision-making and lower cognitive flexibility were associated with suboptimal response to CBT for BED, although findings should be interpreted with caution in light of the sample size and waitlist control design. Future research should examine whether strengthening EF could improve eating and weight outcomes among adolescents with BED who have lower pre-treatment EF.

The predictive value of emotion regulation difficulties and negative mood on short and long-term treatment outcomes in an online guided self-help programme for adults with binge-eating disorder. EUROPEAN EATING DISORDERS REVIEW 2025; 33:163-173.

Abstract
OBJECTIVE Cognitive behaviour therapy (CBT) online guided self-help programs represent efficacious and accessible treatment options for adults with binge-eating disorder (BED), but research on predictors of treatment outcome is scarce. This study aimed to investigate the predictive value of emotion regulation difficulties relative to that of negative mood on short- and longer-term treatment outcomes in an online guided self-help programme for BED above and beyond other predictors (age, sex, baseline BED severity). METHODS Participants were 63 adults (87% female, mean age 37.2 years) with BED. Data was analysed using a hierarchical model approach. RESULTS Emotion regulation difficulties better predicted both weekly binge-eating frequency and eating disorder (ED) pathology at posttreatment than negative mood, after controlling for the effect of age, sex and baseline BED severity. At 6-month follow-up, neither emotion regulation difficulties nor negative mood further added to the prediction of weekly binge-eating frequency, whereas negative mood, but not emotion regulation difficulties, did so for ED pathology. CONCLUSION These findings indicate that emotion regulation difficulties at treatment begin might be a relevant predictor of immediate treatment outcome in online guided self-help for adults with BED but might have lower impact on longer-term treatment outcome than negative mood.

Abstract
Attentional biases towards food play an important role in the pathology of binge eating disorder (BED). Later stage electrophysiological potentials (P300, late positive potential) present promising markers of motivated attention with high temporal, albeit low spatial resolution. Complementing this, the N2pc is an earlier-latency component providing the possibility of more directly analyzing visuospatial attention. Therefore, we tested a group with BED (N = 60), as well as an overweight (OW; N = 28) and normal weight (NW; N = 30) group without BED in a Go/No-Go paradigm using food and nonfood distractor images. Only the OW group in exclusively the Go trials displayed a stronger spatial attention allocation towards nonfood distractors as evidenced by an increased N2pc amplitude. In the P300's time window, the OW group displayed no attentional bias towards food and the NW group only did so in the absence of a target. Solely the BED group allocated more motivated attention towards food distractors both in Go and No-Go trials. In the following late positive potential (LPP), the OW group exhibited a general attentional bias towards food distractors, while the BED group only did so in the absence of a target. These results are discussed in light of the incentive sensitization theory and a potential early attentional suppression of potent distractors.

Abstract
INTRODUCTION Pharmacological and other treatments for binge eating disorder (BED) predate its inclusion as the third main eating disorder in the 2013 DSM-5. Currently, second in line to psychological therapy are psychotropics such as antidepressants, anticonvulsants and stimulants. AREAS COVERED This review summarizes the evidence and emerging evidence on the pharmacotherapies for BED and their potential for wider use. EXPERT OPINION Pharmacotherapy has utility as an alternative or adjunctive treatment for those exhibiting insufficient response to, or not preferencing, psychological interventions. Medications may also benefit individuals with BED and other co-occurring mental health conditions, such as depression and attention deficit hyperactivity disorder. In addition, there are several agents (e.g. glucagon like peptide-1 receptor agonists and the combination of naltrexone-bupropion) displaying promise for weight and binge eating reduction in people with BED and high BMI. Future research should extend the understanding of the role of medication in BED, focusing on their sustained effects over time, when and if they may be ceased, their effectiveness in people with adequate weight, and the risks associated with weight loss in those with BED and high weight.

Abstract
Background Limited research into binge eating disorder (BED), a low treatment rate, and a lack of treatment rights, reflects a marginalized disorder in society and a treatment context. Aim The aim of this study was to gain a deeper understanding of the psychopathology of BED, by exploring the patients' meanings related to the disorder and the role of the body in the treatment of BED. Method Qualitative methodology using a reflexive thematic analysis. The data material is based on semi-structured in-depth interviews with six cis-gendered women who had previously completed an inpatient treatment program for BED at a department for EDs and met the criteria for 307.51 Binge Eating Disorder in DSM-5. Results The qualitative analysis rendered two meta-themes comprising six themes and 12 subthemes. The initial meta-theme was "Relational challenges and feelings could not be talked about at home." The secondary meta-theme was "Body contempt disturbs the experience of self and others" and the third was "Their body has not been a theme in previous treatment." This categorization depicts a narrative of the disorder in terms of development, current condition, and experiences with prior treatment. Discussion The findings indicate that shame and disgust are central to playing pivotal roles in the embodiment of BED, highlighting the significance of addressing one's relationship with their body for achieving recovery and preventing an experienced repetition of the perceived rejection as a child.

Abstract
Specific psychological treatments have demonstrated efficacy and represent the first-line approaches recommended for anorexia nervosa, bulimia nervosa, and binge-eating disorder. Unfortunately, many patients, particularly those with anorexia nervosa, do not derive sufficient benefit from existing treatments, and better or alternative treatments for eating disorders are needed. Less progress has been made in developing pharmacologic options for eating disorders. No medications approved for anorexia nervosa exist, and only one each exists for bulimia nervosa and for binge-eating disorder; available data indicate that most patients fail to benefit from available medications. Longer and combined treatments have generally not enhanced outcomes. This review presents emerging findings from more complex and clinically relevant adaptive treatment designs, as they offer some clinical guidance and may serve as models for future enhanced treatment research.

Abstract
BACKGROUND Eating disorder (ED) research has embraced a network perspective of psychopathology, which proposes that psychiatric disorders can be conceptualized as a complex system of interacting symptoms. However, existing intervention studies using the network perspective have failed to find that symptom reductions coincide with reductions in strength of associations among these symptoms. We propose that this may reflect failure of alignment between network theory and study design and analysis. We offer hypotheses for specific symptom associations expected to be disrupted by an app-based intervention, and test sensitivity of a range of statistical metrics for identifying this intervention-induced disruption. METHODS Data were analyzed from individuals with recurrent binge eating who participated in a randomized controlled trial of a cognitive-behavioral smartphone application. Participants were categorized into one of three groups: waitlist (n = 155), intervention responder (n = 49), and intervention non-responder (n = 77). Several statistical tests (bivariate associations, network-derived strength statistics, network invariance tests) were compared in ability to identify change in network structure. RESULTS Hypothesized disruption to specific symptom associations was observed through change in bivariate correlations from baseline to post-intervention among the responder group but were not evident from symptom and whole-of-network based network analysis statistics. Effects were masked when the intervention group was assessed together, ignoring heterogeneity in treatment responsiveness. CONCLUSION Findings are consistent with our contention that study design and analytic approach influence the ability to test network theory predictions with fidelity. We conclude by offering key recommendations for future network theory-driven interventional studies.

Abstract
Using data from 165 adult participants who enrolled in four studies of cognitive-behavioral therapy (CBT) for binge-spectrum eating disorders (EDs), this secondary analysis examined 1) whether pretreatment hopelessness predicted posttreatment eating pathology, loss-of-control (LOC) eating frequency, and purging frequency; 2) whether treatment had an indirect effect on those outcomes through change in hopelessness; and 3) whether treatment had an indirect effect on hopelessness through those ED measures. The Eating Disorder Examination was used to assess overall eating pathology, LOC frequency, and purging frequency. Hopelessness was measured with one item from the Beck Depression Inventory-II. Regression models showed that pretreatment hopelessness predicted posttreatment LOC eating frequency but not overall eating pathology or purging frequency. Single-group tests of indirect effects showed no effect of reduction in hopelessness on reduction in ED symptoms, but there was an effect of reduction in ED symptoms on reduction in hopelessness.

Abstract
OBJECTIVE Our study aimed to review the outcome measures/assessment instruments used and to assess their heterogeneity/homogeneity in eating disorders (EDs) randomised controlled trials. METHODS APA PsycInfo, PubMed, and Embase were searched in December 2022 to identify studies published between and inclusive of January 2012 and December 2022. Inclusion/exclusion criteria were: (1) complete articles published in peer-reviewed scientific journals, which were: (2) randomised trials, (3) in a clinical setting (4) with human subjects, (5) with an ICD or DSM diagnosis of Anorexia Nervosa, Binge Eating Disorder, or Bulimia Nervosa. The selected papers also: (6) used one or more standardised instruments designed to measure one or more psychometric characteristics associated with ED as a primary or secondary outcome, as judged by the authors of this systematic review, and (7) were published in English or Danish. RESULTS Ninety one articles were included, and a total of 196 outcome measures were collected. DISCUSSION The diversity of outcome measures in ED trials hampers result comparability and data integration. We suggest creating a core outcome measure set using the Delphi method, including clinician and patient-reported ED assessments, along with relevant comorbidity scales.

Abstract
Binge eating disorder (BED) is the most prevalent eating disorder. Treatment options include pharmacotherapy as well as psychotherapy, with the latter recommended as a first-line option. However, the use of psychotherapeutic interventions poses several challenges. Antidepressants are easily accessible, but they lack robust evidence-base. This systematic review aims to comprehensively examine the efficacy and safety of antidepressants for the treatment of BED. Five databases were searched for randomized controlled trials (RCTs) comparing antidepressants vs. placebo in BED until 23/11/2023. Pairwise meta-analytic evaluations were performed. The primary outcomes were remission and binge eating frequency. Secondary outcomes were response to treatment, eating psychopathology, depression, anxiety, body weight, Body Mass Index (BMI), all-cause discontinuation, discontinuation due to adverse effects and total adverse events. Sixteen RCTs with a total of 984 participants were meta-analysed. Antidepressants were more effective than placebo in achieving remission (RR: 1.39, 95 % CI: 1.04 to 1.86) and in reducing binge eating episodes (SMD: -0.29, 95 % CI: -0.51 to -0.06). Similarly, in the secondary outcomes of response and depression, antidepressants demonstrated superiority over placebo. Antidepressants appear to be effective in reducing symptoms of BED. Small samples and effect sizes hinder the generalizability and clinical utility of these results. There is a lack of follow-up findings regarding the maintenance of effects. There is a pressing need for more RCTs examining antidepressants and other types of pharmacotherapy. Future research should include larger number of participants and increase the duration of follow-up.

Abstract
INTRODUCTION Web-based guided self-help cognitive behavioral therapy-enhanced (CBT-E) is a 12-weeks, 12-sessions, digitalized version of part II of the self-help book Overcoming Binge Eating. This intervention is effective when offered under controlled circumstances in a randomized-controlled-trial. It is unknown how patients with binge-eating disorder (BED) respond to this intervention when offered in real-world clinical-settings. The aim of this study is to examine post-intervention effectiveness of guided self-help CBT-E for BED in real-world settings. METHOD The present study used a cohort-design examining the effectiveness of web-based guided self-help CBT-E according to an intention-to-treat (ITT) analysis. BED patients (n = 278) were assessed pre- and post-intervention. The primary outcome was reduction in binge-eating episodes. Other outcomes were full-recovery (EDE-Q score <2.77 and abstinence from binge-eating episodes), impaired psychosocial functioning, defined as secondary impairment, and general psychopathology post-intervention. RESULTS The number of binge-eating episodes reduced by an average of 16 binge-eating episodes per 4 weeks pre-intervention to five binge-eating episodes during the last 4 weeks of treatment. Abstinence from binge eating was reported by 30%, and 28% reported full recovery. Effect sizes (Cohen's d) were large (d ≥ 1.0) for all outcome measures. There were no differences in outcomes between the ITT and the completers sample. DISCUSSION Guided self-help CBT-E is associated with significant improvements. The effects of guided self-help CBT-E offered in a real-world-setting are comparable to self-help CBT-E offered in a randomized-controlled-trial. However, it should be noted that comparisons with randomized-controlled-trials requires caution. Longer-term follow-up data are necessary to measure persistence of treatment benefits. PUBLIC SIGNIFICANCE Offering CBT-E as a web-based guided self-help intervention has several benefits for patients with BED. Guided self-help CBT-E is associated with significant improvements on the short term when offered in real-world clinical settings.

Abstract
PURPOSE OF REVIEW The present review describes the recent literature on treatment for binge-eating disorder (BED) in adults and youth, with a particular focus on research gaps, emerging treatments, and future research directions. RECENT FINDINGS Evidence supports the efficacy of several treatment modalities in adults, including self-help treatment, clinician-led psychotherapy, and pharmacotherapy; the largest effect sizes have been found for psychotherapies, most of which were cognitive-behavioral in orientation. Adapted psychotherapies for youth also show promise but lack a robust body of evidence. Predictors, moderators, and mediators of treatment outcome remain poorly understood; individuals with BED continue to experience significant barriers to treatment; and research is needed to address suboptimal treatment response. Recent work has highlighted the potential of adaptive interventions and investigation of novel mechanisms to address these gaps. Research on BED treatment continues to grow, though critical questions must be answered to improve treatment efficacy across the lifespan.

Abstract
Importance Binge eating disorder (BED) is one of the most frequent eating pathologies and imposes substantial emotional and physical distress, yet insufficient health care resources limit access to specialized treatment. Web-based self-help interventions emerge as a promising solution, offering more accessible care. Objective To examine the effectiveness of a web-based cognitive behavioral self-help intervention for individuals with BED. Design, Setting, and Participants This 2-arm, parallel-group randomized clinical trial conducted from January 15, 2021, to August 3, 2022, in Germany and other German-speaking countries enrolled patients aged 18 to 65 years who met the diagnostic criteria for BED (according to the Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition]). Data analysis occurred between January 27 and September 4, 2023, following our statistical analysis plan. Interventions Participants were randomized to a web-based self-help intervention or a waiting-list control condition. Main Outcomes and Measures The primary outcome was a change in objective binge eating episodes from baseline to after treatment. Secondary outcomes included global eating pathology, clinical impairment, work capacity, well-being, comorbid psychopathology, self-esteem, and emotion regulation. Results A total of 1602 patients were screened, of whom 154 (mean [SD] age, 35.93 [10.59] years; 148 female [96.10%]) fulfilled the criteria for BED and were randomized (77 each to the intervention and control groups). The web-based intervention led to significant improvements in binge eating episodes (Cohen d, -0.79 [95% CI, -1.17 to -0.42]; P < .001), global eating psychopathology (Cohen d, -0.71 [95% CI, -1.07 to -0.35]; P < .001), weekly binge eating (Cohen d, -0.49 [95% CI, -0.74 to -0.24]; P < .001), clinical impairment (Cohen d, -0.75 [95% CI, -1.13 to -0.37]; P < .001), well-being (Cohen d, 0.38 [95% CI, 0.01 to 0.75]; P = .047), depression (Cohen d, -0.49 [95% CI, -0.86 to -0.12]; P = .01), anxiety (Cohen d, -0.37 [95% CI, -0.67 to -0.07]; P = .02), self-esteem (Cohen d, 0.36 [95% CI, 0.13 to 0.59]; P = .003), and emotion regulation (difficulties: Cohen d, -0.36 [95% CI, -0.65 to -0.07]; P = .01 and repertoire: Cohen d, 0.52 [95% CI, 0.19 to 0.84]; P = .003). Conclusion and Relevance In this randomized clinical trial of a web-based self-help intervention for patients with BED, the findings confirmed its effectiveness in reducing binge eating episodes and improving various mental health outcomes, highlighting a scalable solution to bridge the treatment gap for this condition. Trial Registration ClinicalTrials.gov Identifier: NCT04876183.

Int J Eat Disord 2024; 57:1268-1273. [PMID: 38321617 PMCID: PMC11093697 DOI: 10.1002/eat.24141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 12/15/2023] [Accepted: 01/08/2024] [Indexed: 02/08/2024]
Abstract
OBJECTIVE To test whether overvaluation of shape/weight at the end of treatment prospectively predicts relapse at 12-month follow-up in patients with binge-eating disorder (BED). METHOD Participants were 129 patients with BED who achieved abstinence from binge eating after 6 months of behaviorally-based weight-loss treatments in a clinical trial. Independent assessments conducted at posttreatment and at 12-month follow-up included the Eating Disorder Examination interview, the Beck Depression Inventory, and weight measurements. RESULTS Of the 129 participants who attained abstinence from binge-eating at posttreatment, 46 (36%) were categorized with clinical overvaluation and 83 (64%) with subclinical overvaluation; 115 (89%) were re-assessed at 12-month follow-up. Participants with overvaluation at posttreatment were significantly more likely than those without to relapse at 12-months to non-abstinence from binge eating (54% vs. 28%) and to diagnosis-level binge-eating frequency of once weekly or greater (31% vs. 13%). Overvaluation at posttreatment predicted significantly higher eating-disorder psychopathology and depression scores at 12-month follow-up but were unrelated to weight and weight changes. Treatment groups did not have main or interaction effects; posttreatment overvaluation effects were observed regardless of treatment and of covarying for posttreatment value of dependent variables. CONCLUSIONS Our findings suggest that overvaluation of shape/weight at the end of treatment predicts relapse and heightened eating-disorder psychopathology and depression scores 1 year later in patients who achieved abstinence from binge eating with behaviorally-based treatments. Overvaluation of shape/weight has significant clinical implications and warrants consideration as a diagnostic specifier for BED as it provides important prospective prognostic information. PUBLIC SIGNIFICANCE Although effective treatments are available for binge-eating disorder, relapse following successful treatments is not uncommon. Almost nothing is known about what predicts relapse following treatments for binge-eating disorder. Our study found that overvaluation of shape/weight (i.e., body image concerns that overly impact self-worth) at posttreatment prospectively predicted relapse and higher eating-disorder psychopathology and depression 1 year later in patients who achieved binge-eating abstinence with behaviorally based treatments.

Abstract
Individuals with binge eating disorder (BED) exhibit a biased attention towards food stimuli. Against this backdrop, the present study with pre-registered design (ID: DRKS00012984) tested whether (a) a training designed to reduce attentional food processing indeed modifies this bias, (b) this reduction is evident in several measures of food-related attention and (c) this is associated with reductions in craving, binge frequency over the past 28 days and calories eaten in a laboratory based bogus taste test. Individuals with BED were randomly allocated to four sessions of either an attentional bias modification training (ABMT; n = 39) or a comparable no-modification control training (CT; n = 27). In all measures assessed via eye-tracking - dwell time bias, dwell time bias variability and first fixation bias - food-related bias decreased in the ABMT relative to the CT. Against our hypothesis, no differential between-group effects were found for reaction time (RT) bias and its variability as well as for calories consumed in a bogus taste test. By contrast, reductions in binge frequency and subjective craving were found for both groups. Taken together, the tendency to preferentially process food seems a modifiable phenomenon in individuals with BED. However, modifying this selective viewing pattern does not seem a prerequisite for a successful reduction of binge frequency.

Food Cravings and Obesity in Women with Polycystic Ovary Syndrome: Pathophysiological and Therapeutic Considerations. Nutrients 2024; 16:1049.

Abstract
Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, constitutes a metabolic disorder frequently associated with obesity and insulin resistance (IR). Furthermore, women with PCOS often suffer from excessive anxiety and depression, elicited by low self-esteem due to obesity, acne, and hirsutism. These mood disorders are commonly associated with food cravings and binge eating. Hypothalamic signaling regulates appetite and satiety, deteriorating excessive food consumption. However, the hypothalamic function is incapable of compensating for surplus food in women with PCOS, leading to the aggravation of obesity and a vicious circle. Hyperandrogenism, IR, the reduced secretion of cholecystokinin postprandially, and leptin resistance defined by leptin receptors' knockout in the hypothalamus have been implicated in the pathogenesis of hypothalamic dysfunction and appetite dysregulation. Diet modifications, exercise, and psychological and medical interventions have been applied to alleviate food disorders, interrupting the vicious circle. Cognitive-behavioral intervention seems to be the mainstay of treatment, while the role of medical agents, such as GLP-1 analogs and naltrexone/bupropion, has emerged.

Abstract
Atypical anorexia nervosa (AAN), purging disorder (PD), night eating syndrome (NES), and subthreshold bulimia nervosa and binge-eating disorder (Sub-BN/BED) are the five categories that comprise the 'Other Specified Feeding or Eating Disorder' (OSFED) category in the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). In this review, we examine problems with the diagnostic criteria that are currently proposed for the five OSFED types. We conclude that the existing diagnostic criteria for OSFED are deficient and fall short of accurately describing the complexity and individuality of those with these eating disorders (EDs). Therefore, to enhance the quality of life of people with OSFED, diagnostic criteria for the condition should be applied uniformly in clinical and research settings.

Abstract
Eating disorders (EDs) and obesity are complex health conditions sharing various risk and maintenance factors, intensified in cases of comorbidity. This review explores the similarities and connections between these conditions, examining different facets from a multidisciplinary perspective, among them comorbidities, metabolic and psychological factors, neurobiological aspects, and management and therapy implications. We aim to investigate the common characteristics and complexities of weight and EDs and explore their interrelationships in individuals who experience both. The rising prevalence of EDs in people with obesity necessitates integrated approaches to study this comorbidity and to identify and analyze both common and distinct features of these conditions. This review may offer new opportunities for simultaneous prevention and management approaches, as well as future lines of research.

Abstract
OBJECTIVES Binge spectrum disorders are prevalent worldwide. Psychiatric and medical comorbidities are common, and societal costs are significant. Evidence-based treatment remains underutilized. Cognitive behavioral therapy is the recommended first-line treatment, but pharmacotherapy may be easier to access. INTERVENTIONS Meta-analytic evidence directly comparing cognitive behavioral therapy with pharmacotherapy is lacking. We aimed to compare the effects of cognitive behavioral therapy interventions with any pharmacological treatment for binge spectrum disorders. We searched PubMed, Embase, CENTRAL, ClinicalTrials.gov and reference lists for randomized controlled trials comparing cognitive behavioral therapy with any pharmacotherapy for bulimia nervosa/binge eating disorder and performed pairwise meta-analytic evaluations. PRIMARY OUTCOMES Primary outcomes are remission and frequency of binges. Secondary outcomes are frequency of purges, response, eating disorder psychopathology, weight/body mass index, depression, anxiety, quality of life and dropouts. RESULTS Eleven randomized controlled trials comparing cognitive behavioral therapy with fluoxetine/imipramine/desipramine/methylphenidate/sibutramine were identified (N = 531). Cognitive behavioral therapy was superior to antidepressants in terms of remission, frequency of binges and eating disorder psychopathology. There were no statistically significant differences for any of the individual cognitive behavioral therapy vs drug comparisons in terms of response/depression/anxiety/weight/quality of life/dropouts. Cognitive behavioral therapy was not superior to sibutramine/methylphenidate for the primary outcomes. CONCLUSIONS Data are scarce, comparisons underpowered and, considering the inherent methodological limitations of psychotherapy trials, questions arise regarding the presumed superiority of cognitive behavioral therapy. Further research is needed.

Abstract
BACKGROUND Binge-eating disorder (BED) co-occurs with neurobehavioral alterations in the processing of disorder-relevant content such as visual food stimuli. Whether neurofeedback (NF) directly targeting them is suited for treatment remains unclear. This study sought to determine feasibility and estimate effects of individualized, functional near-infrared spectroscopy-based real-time NF (rtfNIRS-NF) and high-beta electroencephalography-based NF (EEG-NF), assuming superiority over waitlist (WL). METHODS Single-center, assessor-blinded feasibility study with randomization to rtfNIRS-NF, EEG-NF, or WL and assessments at baseline (t0), postassessment (t1), and 6-month follow-up (t2). NF comprised 12 60-min food-specific rtfNIRS-NF or EEG-NF sessions over 8 weeks. Primary outcome was the binge-eating frequency at t1 assessed interview-based. Secondary outcomes included feasibility, eating disorder symptoms, mental and physical health, weight management-related behavior, executive functions, and brain activity at t1 and t2. RESULTS In 72 patients (intent-to-treat), the results showed feasibility of NF regarding recruitment, attrition, adherence, compliance, acceptance, and assessment completion. Binge eating improved at t1 by -8.0 episodes, without superiority of NF v. WL (-0.8 episodes, 95% CI -2.4 to 4.0), but with improved estimates in NF at t2 relative to t1. NF was better than WL for food craving, anxiety symptoms, and body mass index, but overall effects were mostly small. Brain activity changes were near zero. CONCLUSIONS The results show feasibility of food-specific rtfNIRS-NF and EEG-NF in BED, and no posttreatment differences v. WL, but possible continued improvement of binge eating. Confirmatory and mechanistic evidence is warranted in a double-blind randomized design with long-term follow-up, considering dose-response relationships and modes of delivery.

Abstract
Binge-eating disorder (BED) is a psychiatric disorder characterized by recurrent episodes of eating a large amount of food in a discrete period of time while experiencing a loss of control. Cognitive behavioral therapy-enhanced (CBT-E) is a recommended treatment for binge-eating disorder and is typically offered through 20 sessions. Although binge-eating disorder is highly responsive to CBT-E, the cost of treating these patients is high. Therefore, it is crucial to evaluate the efficacy of low-intensity and low-cost treatments for binge-eating disorder that can be offered as a first line of treatment and be widely disseminated. The proposed noninferiority randomized controlled trial aims to determine the efficacy of web-based guided self-help CBT-E compared to treatment-as-usual CBT-E. Guided self-help will be based on a self-help program to stop binge eating, will be shorter in duration and lower intensity, and will require fewer therapist hours. Patients with binge-eating disorder (N = 180) will be randomly assigned to receive guided self-help or treatment-as-usual. Assessments will take place at baseline, mid-treatment, at the end of treatment, and at 20- and 40-weeks post-treatment. Treatment efficacy will be measured by examining the reduction in binge-eating days in the previous 28 days between baseline and the end of treatment between groups, with a noninferiority margin (Δ) of 1 binge-eating day. Secondary outcomes will include full remission, body shape dissatisfaction, therapeutic alliance, clinical impairment, health-related quality of life, attrition, and an economic evaluation to assess cost-effectiveness and cost-utility. The moderators examined will be baseline scores, demographic variables, and body mass index. It is expected that guided self-help is noninferior in efficacy compared to treatment-as-usual. The proposed study will be the first to directly compare the efficacy and economically evaluate a low-intensity and low-cost binge-eating disorder treatment compared to treatment-as-usual. If guided self-help is noninferior to treatment-as-usual in efficacy, it can be widely disseminated and used as a first line of treatment for patients with binge-eating disorder. The Dutch trial register number is R21.016. The study has been approved by the Medical Research Ethics Committees United on May 25th, 2021, case number NL76368.100.21.

Abstract
BACKGROUND Eating disorders are seen mainly as a problem affecting women, not just by the public at large, but also in specialized circles. Although it is true that more women than men suffer from all types of eating disorder, pertinent reviews have clearly shown that they do indeed occur in men, and that the available evidence on the matter is limited. The stigmatization of men with eating disorders makes it harder for these men, and for the relevant professionals, to recognize the symptoms and to seek or provide help. METHODS This review is based on publications retrieved by a selective search in PubMed on the epidemiological, diagnostic, clinical, and therapeutic aspects of eating disorders in men. RESULTS Current estimated lifetime prevalences in men are 0.2% for anorexia nervosa, 0.6% for bulimia nervosa, and 1% for bingeeating disorder; the corresponding figures for women are 1.4%, 1.9%, and 2.8%. Men and women may display different manifestations. Women are thought to be mainly seeking a slim figure and weight reduction; men, a muscular build. The established Germanlanguage screening and diagnostic tools, however, do not cover the types of symptoms that are more common in men. Little is known about whether treatment yields comparable results in men and women. CONCLUSION It is important to combat the stigmati - zation of men with eating disorders and to remove the obstacles to their appropriate diagnosis and treatment. The current methods of screening and diagnosis need to be adapted to take account of the special aspects of abnormal eating behavior in men. It remains unclear whether and how the disorderspecific treatment of these conditions in men should differ from their treatment in women.

Abstract
Background Speculation exists as to whether lisdexamfetamine dimesylate (LDX) acts on the functional connectivity (FC) of brain networks that modulate appetite, reward, or inhibitory control in binge-eating disorder (BED). Better insights into its action may help guide the development of more targeted therapeutics and identify who will benefit most from this medication. Here, we use a comprehensive data-driven approach to investigate the brain FC changes that underlie the therapeutic action of LDX in patients with BED. Methods Forty-six participants with moderate to severe BED received LDX titrated to 50 or 70 mg for an 8-week period. Twenty age-matched healthy control participants were also recruited. Resting-state functional magnetic resonance imaging was used to probe changes in brain FC pre- and post treatment and correlated with change in clinical measures. Results Ninety-seven percent of trial completers (n = 31) experienced remission or a reduction to mild BED during the 8-week LDX trial. Widespread neural FC changes occurred, with changes in default mode to limbic, executive control to subcortical, and default mode to executive control networks associated with improvements in clinical outcomes. These connections were not distinct from control participants at pretreatment but were different from control participants following LDX treatment. Pretreatment connectivity did not predict treatment response. Conclusions FC between networks associated with self-referential processing, executive function, and reward seem to underlie the therapeutic effect of LDX in BED. This suggests that LDX activates change via multiple systems, with most changes in compensatory networks rather than in those characterizing the BED diagnosis.

Abstract
Low meaning in life has been proposed as an important factor in the maintenance of eating disorders and previous findings suggest that targeting meaning might optimize treatment effectiveness. The current randomized controlled trial aimed to investigate the efficacy of meaning-centered psychotherapy adjusted for eating disorders (MCP-ED) to improve meaning in women with high weight and shape concerns. Female students with high weight and shape concerns (N = 134) were randomly assigned to the waiting-list control condition or the experimental condition, in which they followed six weekly individual sessions of MCP-ED. Self-report measures of meaning, eating disorder symptoms, general distress, psychological well-being, and satisfaction with meaningful life domains were completed at baseline, after the final session of MCP-ED or a 7-week waiting period, and at 4-week follow-up. Participants in the experimental condition showed a stronger increase in meaning than participants in the waiting-list condition after the intervention and at follow-up. The intervention also resulted in lower eating disorder symptoms and general distress, and higher psychological well-being and satisfaction with meaningful life domains. Findings support the efficacy of MCP-ED as an intervention to increase meaning and point to the relevance of examining whether adding MCP-ED to regular treatment might increase treatment effectiveness in individuals with eating disorders.

Abstract
The prevalence of eating disorders has been increasing over the last 50 years. Binge eating disorder (BED) and bulimia nervosa (BN) are two typical disabling, costly and life-threatening eating disorders that substantially compromise the physical well-being of individuals while undermining their psychological functioning. The distressing and recurrent episodes of binge eating are commonly observed in both BED and BN; however, they diverge as BN often involves the adoption of inappropriate compensatory behaviors aimed at averting weight gain. Normal eating behavior is coordinated by a well-regulated trade-off between intestinal and central ingestive mechanism. Conversely, despite the fact that the etiology of BED and BN remains incompletely resolved, emerging evidence corroborates the notion that dysbiosis of gastrointestinal microbiome and its metabolites, alteration of gut-brain axis, as well as malfunctioning central circuitry regulating motivation, execution and reward all contribute to the pathology of binge eating. In this review, we aim to outline the current state of knowledge pertaining to the potential mechanisms through which each component of the gut-brain axis participates in binge eating behaviors, and provide insight for the development of microbiome-based therapeutic interventions that hold promise in ameliorating patients afflicted with binge eating disorders.

Noradrenergic control of neurobehavior in human binge-eating disorder and obesity (NOBEAD): A smartphone-supported behavioral emotion regulation intervention study protocol integrating molecular brain imaging. Int J Eat Disord 2024; 57:206-220.

Abstract
OBJECTIVE The neurobehavioral underpinnings of binge-eating disorder (BED), co-occurring with obesity (OB), are largely unknown. This research project conceptualizes BED as a disorder with dysfunctional emotion regulation (ER) linked with changes in central noradrenaline (NA) transmission and NA-modulated neuronal networks. METHODS We expect abnormalities in NA activity in both BED and OB, but most pronounced in BED. We expect these abnormalities to be modifiable through state-of-the-art ER intervention, specifically in BED. To assess the role of NA transmission, we will quantify changes in NA transporter (NAT) availability using the highly NAT-specific [11 C]methylreboxetin (MRB) and positron emission tomography-magnetic resonance imaging (PET-MRI) that allows measuring molecular and neuronal changes before and after an ER intervention. Individual 12-session smartphone-supported acceptance-based behavioral therapy will be conducted to improve ER. Thirty individuals with OB and BED (OB + BED), 30 individuals with OB without BED (OB - BED), and 20 individuals with normal weight will undergo assessments of NAT availability and neuronal network activity under rest and stimulated conditions, clinical interviews, self-report questionnaires on eating behavior, ER, mental and physical health, and quality of life, and neuropsychological tests on executive function. Afterwards, in an experimental randomized-controlled design, individuals with OB + BED and OB - BED will be allocated to smartphone-supported ER intervention versus a waitlist and re-assessed after 10 weeks. DISCUSSION By obtaining biological and behavioral markers, the proposed study will disentangle the involvement of NAT and the central NA system in the modulation of emotion-supporting neuronal networks that influence eating behavior. Neurobehavioral mechanisms of change during an ER intervention will be determined. TRIAL REGISTRATION German Clinical Trials Register (DRKS): DRKS00029367. PUBLIC SIGNIFICANCE This study investigates the central noradrenaline system by using hybrid brain imaging in conjunction with emotion regulation as a putative core biological mechanism in individuals with obesity with or without binge-eating disorder that is targeted by emotion regulation intervention. The results will provide a molecular signature beyond functional imaging biomarkers as a predictive biomarker toward precision medicine for tailoring treatments for individuals with binge-eating disorders and obesity.

Abstract
OBJECTIVE Despite the increasing popularity of neurofeedback (NF), aiming at voluntary modulation of dysfunctional prefrontal cortex (PFC) signals in the treatment of binge-eating disorder (BED) and/or overweight, mechanisms remain poorly understood. METHODS Based on a randomized-controlled trial offering 12 food-specific real-time functional near-infrared spectroscopy (rtfNIRS)-NF sessions to participants with BED (n = 22), this preregistered study examined (1) online regulation success as predictor for offline regulation success, defined by PFC signals during regulation versus watch, and subjective regulation success, and (2) changes in loss of control (LOC) eating after vs. before and across 12 rtfNIRS-NF-sessions. RESULTS Higher online regulation success expectedly predicted better subjective, but worse offline regulation success. LOC eating decreased after vs. before, but not over rtfNIRS-NF-sessions, and was not associated with subjective or offline regulation success. CONCLUSIONS The association between online and subjective regulation success confirmed the presumed mechanism of operant conditioning underlying rtfNIRS-NF-learning. The contrary association between online and offline regulation indicated differential PFC involvement upon subtraction of automatic food-specific responses from regulation signals for offline success. Decreased LOC eating after food-specific rtfNIRS-NF-sessions suggested the potential of NF in BED treatment. SIGNIFICANCE Results may guide the optimization of future NF studies in larger samples with BED.

Abstract
BACKGROUND Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but there is a dearth of controlled research examining pharmacotherapies as maintenance treatments for responders to initial interventions. This gap in the literature is particularly critical for pharmacotherapy for BED which is associated with relapse following discontinuation. The current study tested the efficacy of naltrexone/bupropion maintenance treatment amongst responders to acute treatments for BED. METHODS Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested naltrexone/bupropion as maintenance treatment for responders to acute treatments with naltrexone/bupropion and/or behavioral weight-loss therapy for BED with comorbid obesity. Sixty-six patients (84.8% women, mean age 46.9, mean BMI 34.9 kg/m2) who responded to acute treatments were re-randomized to placebo (N = 34) or naltrexone/bupropion (N = 32) for 16 weeks; 86.3% completed posttreatment assessments. Mixed models and generalized estimating equations comparing maintenance treatments (naltrexone/bupropion v. placebo) included main and interactive effects of acute treatments. RESULTS Intention-to-treat binge-eating remission rates following maintenance treatments were 50.0% (N = 17/34) for placebo and 68.8% (N = 22/32) for naltrexone/bupropion. Placebo following response to acute treatment with naltrexone/bupropion was associated with significantly decreased probability of binge-eating remission, increased binge-eating frequency, and no weight loss. Naltrexone/bupropion following response to acute treatment with naltrexone/bupropion was associated with good maintenance of binge-eating remission, low binge-eating frequency, and significant additional weight loss. CONCLUSIONS Adult patients with BED with co-occurring obesity who have good responses to acute treatment with naltrexone/bupropion should be offered maintenance treatment with naltrexone/bupropion.

Binge-eating adolescent treatment (BEAT) - findings from a pilot study on effects and acceptance of a blended treatment program for youth with loss of control eating. BMC Psychol 2023; 11:415.

Abstract
BACKGROUND Loss of Control Eating (LOC) is the most prevalent form of eating disorder pathology in youth, but research on evidence-based treatment in this group remains scarce. We assessed for the first time the effects and acceptance of a blended treatment program for youth between 14 and 24 years with LOC (Binge-eating Adolescent Treatment, BEAT). METHODS Twenty-four youths (mean age 19.1 years) participated in an active treatment of nine-weeks including three face-to-face workshops and six weekly email-guided self-help sessions, followed by four email guided follow-up sessions, one, three, six and 12 months after the active treatment. All patients completed a two-weeks waiting-time period before treatment begin (within-subject waitlist control design). RESULTS The number of weekly LOC episodes substantially decreased during both the waiting-time (effect size d = 0.45) and the active treatment (d = 1.01) period and remained stable during the subsequent 12-months follow-up (d = 0.20). The proportion of patients with full-threshold binge-eating disorder (BED) diagnoses decreased and transformed into LOC during the study course, while the abstainer rate of LOC increased. Values for depressive symptoms (d = 1.5), eating disorder pathology (d = 1.29) and appearance-based rejection sensitivity (d = 0.68) all improved on average from pretreatment to posttreatment and remained stable or further improved during follow-up (d between 0.11 and 0.85). Body weight in contrast remained constant within the same period. Treatment satisfaction among completers was high, but so was the dropout rate of 45.8% at the end of the 12-months follow-up. CONCLUSIONS This first blended treatment study BEAT might be well suited to decrease core symptoms of LOC, depressive symptoms and appearance-based rejection sensitivity. More research is needed to establish readily accessible interventions targeted more profoundly at age-salient maintaining factors such as appearance-based rejection sensitivity, while at the same time keeping dropout rates at a low level. TRIAL REGISTRATION The trial was registered at the German Clinical Trials Register (ID: DRKS00014580; registration date: 21/06/2018).

Abstract
OBJECTIVE Binge-eating disorder (BED) is a prevalent psychiatric disorder associated with obesity. Few evidence-based treatments exist for BED, particularly pharmacological options. This study tested the efficacy of naltrexone/bupropion for BED. METHODS A randomized, double-blind, placebo-controlled, 12-week trial tested naltrexone/bupropion for BED with and without obesity. Eighty-nine patients (70.8% women, 69.7% White, mean age 45.7 y, mean BMI 35.1 kg/m2 , 77.5% with BMI ≥ 30 kg/m2 ) were randomized to placebo (n = 46) or naltrexone/bupropion (n = 43), with randomization stratified by obesity status and gender; 92.1% completed post-treatment assessments. RESULTS Mixed models of binge-eating frequency revealed significant reductions that did not differ significantly between naltrexone/bupropion and placebo. Logistic regression of binge-eating remission rates revealed that naltrexone/bupropion and placebo did not differ significantly. Obesity status did not predict, or moderate, binge-eating outcomes considered either continuously or categorically. Mixed models revealed that naltrexone/bupropion was associated with significantly greater percentage weight loss than placebo. Logistic regression revealed that naltrexone/bupropion had significantly higher rates of attaining ≥5% weight loss than placebo (27.9% vs. 6.5%). Obesity status did not predict or moderate weight-loss outcomes. CONCLUSIONS Naltrexone/bupropion did not demonstrate effectiveness for reducing binge eating relative to placebo but showed effectiveness for weight reduction in patients with BED. Obesity status did not predict or moderate medication outcomes.

Yurkow S, Ivezaj V, Grilo CM. Improvements in cardiovascular disease risk factors associated with modest weight loss following treatment in patients with binge-eating disorder and obesity. Int J Eat Disord 2023; 56:2074-2083. [PMID: 37530200 PMCID: PMC10834830 DOI: 10.1002/eat.24035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 07/23/2023] [Accepted: 07/23/2023] [Indexed: 08/03/2023]
Abstract
BACKGROUND Modest weight losses may be associated with improvements in cardiovascular disease risk factors (CVDRF) in patients with obesity. The effects of weight losses on CVDRF in persons with binge-eating disorder (BED) are unknown. This study prospectively examined changes in CVDRF among patients receiving behaviorally-based weight-loss treatment (BBWLT) who attained modest weight losses (≥5 to <10% and ≥10%). METHOD Of 191 participants, CVDRF variables were re-assessed in 168 participants at posttreatment and in 151 at 12-month follow-up. Participants who attained ≥5 to <10% weight loss were compared to those who did not on CVDRFs (total cholesterol, HDL, LDL, triglycerides, HbA1C, mean plasma glucose, heart rate, and systolic/diastolic blood pressure); similar comparisons were completed for those who attained ≥10% weight loss. RESULTS At posttreatment, ≥5 to <10% weight loss (N = 42; 25.0%) was associated with significant improvements in HbA1c and mean plasma glucose, whereas ≥10% weight loss (N = 40, 23.8%) was associated with significant improvements in total cholesterol, triglycerides, HbA1c, mean plasma glucose, and heart rate. At 12-month follow-up, ≥5 to <10% weight loss (N = 17; 11.1%) was related to significant improvements on HDL, triglycerides, HbA1c, and mean plasma glucose, whereas ≥10% weight loss (N = 40, 26.0%) was associated with significant improvements on all the CVDRF variables (except blood pressure). CONCLUSIONS Modest weight loss is associated with significant improvements in CVDRFs in patients with BED and obesity following treatment and at 12-month follow-up. Future work should examine whether improvements in CVDRF are attributable to weight loss per se and/or to other related lifestyle changes. PUBLIC SIGNIFICANCE STATEMENT Individuals with binge-eating disorder and obesity who attain modest weight loss following treatment exhibit improvements in various measures of cardiovascular disease risk compared to those who do not. While weight loss has been challenging for individuals with binge-eating disorder, clinicians should inform patients of the potential health benefits of modest weight loss. Future research should investigate whether weight loss itself and/or related behavioral lifestyle changes drive improved cardiovascular disease risk factors.

Abstract
Introduction Treatment options such as neurofeedback (NF) that directly target the link between aberrant brain activity patterns and dysfunctional eating behaviors in binge-eating disorder (BED) are emerging. However, virtually nothing is known about mental strategies used to modulate food-specific brain activity and the associated brain-based or subjective success of specific strategies. This study firstly investigated the use of mental strategies in response to individually appetitive food cues in adults with BED and overweight or obesity based on a randomized-controlled trial providing electroencephalography (EEG)- or real-time functional near-infrared spectroscopy (rtfNIRS)-NF to BED. Methods Strategy reports written by participants were classified with qualitative content analysis. Additionally, the mental strategies employed by the N = 23 patients who received EEG-NF targeting the reduction of fronto-central high beta activity were analyzed quantitatively through their link with subjective and EEG-NF regulation success. Results The following eight categories, ordered by frequency in descending order, were found: "Behavior," "Imagination," "Emotion," "Distraction," "Thought," "Concentration," "Self-Talk" and "No Strategy." Linear mixed models revealed "Imagination," "Behavior," and "Thought" strategies as positive predictors of EEG-NF regulation success (defined as high beta activity during regulation beneath the baseline), and "Concentration" as a negative predictor of subjective (i.e., self-reported) NF regulation success. Discussion In conclusion, our study offers a classification system that may be used in future studies assessing strategy use for regulating food-related responses in patients with BED and associated overweight/obesity, providing valuable information on potential benefits of specific strategies and transferability to situations outside the NF treatment.

Abstract
BACKGROUND Psychotherapy is considered central to the effective treatment of eating disorders-focusing on behavioural, psychological, and social factors that contribute to the illness. Research indicates psychotherapeutic interventions out-perform placebo, waitlist, and/or other treatments; but, outcomes vary with room for major improvement. Thus, this review aims to (1) establish and consolidate knowledge on efficacious eating disorder psychotherapies; (2) highlight select emerging psychotherapeutic interventions; and (3) identify knowledge gaps to better inform future treatment research and development. METHODS The current review forms part of a series of Rapid Reviews published in a special issue in the Journal of Eating Disorders to inform the development of the Australian-government-funded National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2023, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, and population studies). Data pertaining to psychotherapies for eating disorders were synthesised and outlined in the current paper. RESULTS 281 studies met inclusion criteria. Behavioural therapies were most commonly studied, with cognitive-behavioural and family-based therapies being the most researched; and thus, having the largest evidence-base for treating anorexia nervosa, bulimia nervosa, and binge eating disorder. Other therapies, such as interpersonal and dialectical behaviour therapies also demonstrated positive treatment outcomes. Emerging evidence supports specific use of Acceptance and Commitment; Integrative Cognitive Affective; Exposure; Mindfulness; and Emotionally-Focused therapies; however further research is needed to determine their efficacy. Similarly, growing support for self-help, group, and computer/internet-based therapeutic modalities was noted. Psychotherapies for avoidant/restrictive food intake disorder; other, and unspecified feeding and eating disorders were lacking evidence. CONCLUSIONS Currently, clinical practice is largely supported by research indicating that behavioural and cognitive-behavioural psychotherapies are most effective for the treatment of eating disorders. However, the efficacy of psychotherapeutic interventions varies across studies, highlighting the need for investment and expansion of research into enhanced variants and novel psychotherapies to improve illness outcomes. There is also a pressing need for investigation into the whole range of eating disorder presentations and populations, to determine the most effective interventions.

The acceptability, feasibility, and preliminary efficacy of a supported online self-help treatment program for binge-eating disorder. Front Psychiatry 2023; 14:1229261. [PMID: 37860164 PMCID: PMC10584326 DOI: 10.3389/fpsyt.2023.1229261] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 09/06/2023] [Indexed: 10/21/2023] Open
Abstract
Introduction Studies in transdiagnostic eating disorder (ED) samples suggest supported online self-help programs (eTherapies) are effective and may improve access to treatment; however, their evaluation in those with binge-eating disorder (BED) is limited. Given BED's high prevalence and low levels of treatment uptake, further eTherapy evaluation is needed to broaden access to effective, evidence-based treatment options. The aim of this study was to investigate the acceptability, feasibility, and preliminary efficacy of a supported eTherapy for those with BED or subthreshold BED, and to examine symptom change across the duration of therapy. Method Nineteen women with BED completed a supported, 10-session Cognitive Behavioural Therapy-based eTherapy in an uncontrolled, pre-post, and 3 months follow up intervention study. Key outcomes were assessed by the Eating Disorder Examination Questionnaire (EDE-Q): objective binge episode (OBE) frequency and ED psychopathology. Feasibility was evaluated via program adherence and dropout, whilst acceptability was assessed through participant feedback post-treatment. Weekly symptom change (ED psychopathology) during treatment was assessed by the Eating Disorder Examination - Questionnaire Short (EDE-QS). Results Generalised estimating equations showed statistically and clinically significant reductions in OBEs and ED psychopathology (large effects) post-treatment, with these decreases maintained at follow up. Across weekly assessment, a marked slowing in the rate of change in ED psychopathology was observed after four sessions of the program. Program feasibility was high (i.e., 84% of content completed), as was program acceptability (i.e., 93% of participants expressed high levels of satisfaction). Discussion These results support the acceptability, feasibility, and preliminary efficacy of a supported eTherapy program for those with BED and suggest the variability of symptom change across the duration of therapy. Future research should further investigate findings in an adequately powered randomised controlled trial.

Abstract
PURPOSE OF REVIEW Binge-eating disorder (BED) is a serious psychiatric problem associated with substantial morbidity that, unfortunately, frequently goes unrecognized and untreated. This review summarizes the current status of behavioral, psychological, pharmacological, and combined treatments for BED in adults with a particular focus on recent findings and advances. RECENT FINDINGS Certain specific psychological treatments, notably CBT and IPT, and to some extent DBT, have demonstrated efficacy and are associated with durable benefits after treatment. Certain specific lower-cost scalable interventions, notably CBTgsh, have demonstrated efficacy and have potential for broader uptake. An important advance is the emerging RCT data indicating that BWL, a generalist and available behavioral lifestyle intervention, has effectiveness that approximates that of CBT for reducing binge eating and eating-disorder psychopathology but with the advantage of also producing modest weight loss. There exists only one pharmacological agent (LDX) with approval by the FDA for "moderate-to-severe" BED. Research with other "off label" medications has yielded modest and mixed outcomes with a few medications statistically superior to placebo over the short-term and almost no longer-term data. Nearly all research combining medications and psychological treatments has failed to enhance outcomes (combined appears superior to pharmacotherapy-only but not to psychotherapy-only). Many people with BED suffer in silence and shame, go untreated, and rarely receive evidence-based treatments. Patients and practitioners need to recognize that research has identified several effective interventions for BED, and these can work quickly for many patients. Future research should identify treatments for those who do not derive benefit from initial interventions, identify additional pharmacological options, test agents with relevant mechanisms of action, and utilize innovative adaptative "SMART" designs to identify treatments to enhance outcomes among initial responders and to test alternative treatments to assist initial non-responders.

Economic evaluation of web-based guided self-help cognitive behavioral therapy-enhanced for binge-eating disorder compared to a waiting list: A randomized controlled trial. Int J Eat Disord 2023; 56:1772-1784.

Abstract
INTRODUCTION The aim is to perform an economic evaluation alongside a randomized controlled trial comparing guided self-help cognitive behavioral therapy-enhanced (CBT-E) for binge-eating disorder (BED) to a waiting list control condition. METHODS BED patients (N = 212) were randomly assigned to guided self-help CBT-E or the 3-month waiting list. Measurements took place at baseline and the end-of-treatment. The cost-effectiveness analysis was performed using the number of binge-eating episodes during the last 28 days as an outcome indicator according to the eating disorder examination. A cost-utility analysis was performed using the EuroQol-5D. RESULTS The difference in societal costs over the 3 months of the intervention between both conditions was €679 (confidence interval [CI] 50-1330). The incremental costs associated with one incremental binge eating episode prevented in the guided self-help condition was approximately €18 (CI 1-41). From a societal perspective there was a 96% likelihood that guided self-help CBT-E led to a greater number of binge-eating episodes prevented, but at higher costs. Each additional quality-adjusted life year (QALY) gained was associated with incremental costs of €34,000 (CI 2494-154,530). With a 95% likelihood guided self-help CBT-E led to greater QALY gain at higher costs compared to waiting for treatment. Based on the National Institute for Health and Clinical Excellence willingness-to-pay threshold of €35,000 per QALY, guided self-help CBT-E can be considered cost-effective with a likelihood of 95% from a societal perspective. DISCUSSION Guided self-help CBT-E is likely a cost-effective treatment for BED in the short-term (3-month course of treatment). Comparison to treatment-as-usual is recommended for future research, as it enables an economic evaluation with a longer time horizon. PUBLIC SIGNIFICANCE Offering treatment remotely has several benefits for patients suffering from binge-eating disorders. Guided self-help CBT-E is an efficacious and likely cost-effective treatment, reducing binge eating and improving quality-of-life, albeit at higher societal costs.

Abstract
Eating disorders are now well acknowledged mental health problems that are common and present in people from diverse sociodemographic backgrounds. The past decade has seen a rapid expansion in research into eating disorder interventions. In response to the increasing burden of eating disorders, the Australian Government Department of Health and Aged Care has implemented significant policy changes to improve patient access to Medicare and inpatient treatment facilities. There are several international clinical practice guidelines and a robust evidence base particularly for first line care with specific psychological therapies, including guidelines for the management of eating disorders in individuals with a high weight. Medications play an important adjunct role in care, and novel neuromodulating treatments, such as psychostimulants, are under study. There is emerging evidence for increased person-centred care, with more choice in the form of alternatives to hospital inpatient programs and more respectful consideration of care for all who experience an eating disorder, including people with high weight.

Abstract
Similarities have been reported between the diagnostic and associated characteristics of binge-eating disorder (BED) and substance-related and non-substance-related disorders. This has resulted in interest in using addiction models to inform clinical care for people with BED. The purpose of this paper was to review features of addiction in BED with a focus on clinical implications. First, we briefly summarize similarities and differences in diagnostic and mechanistic features and symptoms for BED and food addiction, substance-related disorders, and non-substance-related disorders. Then we review aspects of addiction in BED that have clinical implications for screening and treatment of this condition. Similarities in diagnostic criteria between BED and substance-related and non-substance-related disorders include loss of control, greater use than intended, continued use despite adverse consequences, and marked distress. Addiction models may help inform aspects of clinical care of BED, particularly for shared antecedents and mechanisms underlying both disorders and to enhance engagement in treatment. Yet, there are large gaps in evidence regarding the effects of many aspects of addiction models to BED. More research is needed to examine the safety and efficacy of using addiction theories and frameworks for clinical strategies for BED.

Abstract
OBJECTIVE Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but many patients who receive "evidence-based" interventions do not derive sufficient benefit. Given the dearth of controlled research examining treatments for patients who fail to respond to initial interventions, this study tested the efficacy of cognitive-behavioral therapy (CBT) for patients with BED who do not respond to initial acute treatments. METHODS Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested 16-weeks of therapist-led CBT for non-responders to initial treatment (naltrexone/bupropion and/or behavioral therapy) for BED with obesity. Thirty-one patients (mean age 46.3 years, 77.4% women, 80.6% White, mean BMI 38.99 kg/m2 ) who were non-responders to initial acute treatments were randomized to CBT (N = 18) or no-CBT (N = 13), in addition to continuing double-blinded pharmacotherapy. Independent assessments were performed at baseline, throughout treatment, and posttreatment; 83.9% completed posttreatment assessments. RESULTS Intention-to-treat remission rates were significantly higher for CBT (61.1%; N = 11/18) than no-CBT (7.7%; N = 1/13). Mixed models of binge-eating frequency (assessed using complementary methods) converged revealing a significant interaction between CBT and time and a significant main effect of CBT. Binge-eating frequency decreased significantly with CBT but did not change significantly with no-CBT. Since only four patients received behavioral treatment during the acute treatments, we performed "sensitivity-type" analyses restricted to the 27 patients who received pharmacotherapy during the acute treatment and found the same pattern of findings for CBT versus no-CBT. CONCLUSIONS Adult patients with BED who fail to respond to initial pharmacological treatments should be offered CBT. PUBLIC SIGNIFICANCE Even with leading evidence-based treatments for binge-eating disorder, many patients do not derive sufficient benefit. Almost no controlled research has examined treatments for patients who fail to respond to initial interventions. This study found that that cognitive-behavioral therapy was effective for patients with binge-eating disorder who did not respond to initial interventions, with 61% achieving abstinence.

Abstract
OBJECTIVE There has been a significant increase in the number of inpatient admissions for individuals with eating disorders and, with the most critical cases requiring inpatient treatment, it is essential that we continue to improve associated outcomes. The aim of the study was to synthesise the available qualitative literature on the experiences of inpatient admissions for eating disorders to understand individuals' experiences and identify areas that may require further research and/or service development. METHOD Searches were performed on the following online databases: PsycINFO, PsycArticles, PsycTherapy MEDLINE, Embase, CINAHL, ASSIA, Scopus and Proquest Open Access Theses. Only papers with qualitative data regarding individuals' experiences of inpatient eating disorder treatment were considered. The CASP qualitative checklist was used to assess studies and relevant data items were extracted. Thematic synthesis was used to integrate the findings in the identified studies. GRADE-CERQual was used to rate the confidence in the findings. RESULTS Twenty-eight studies were identified which the CASP assessment considered to be adequate. The synthesis produced 5 main themes; 'Care and control', 'Inpatient bubble', 'Being supported and understood', 'Challenges of living with others' eating disorders' and finally 'Relationship to eating disorder'. The GRADE CERQual framework rated findings with high or moderate confidence. CONCLUSIONS Findings reaffirmed the importance of patient-centred care and the significant impact of being separated from normal life with others also experiencing an eating disorder.
