Core Tip
Core Tip: Affecting approximately one fourth of the global population, non-alcoholic fatty liver disease (NAFLD) is the predominant cause of chronic liver disease and for many years it was considered as a disease affecting only obese people. However, a significant proportion of non-obese or even lean individuals develop NAFLD. Therefore, it is of great interest to discuss the differences in prognosis, metabolic profiles and outcomes as well as the current management of lean NAFLD patients as compared with both obese NAFLD patients and lean healthy controls.
