Core Tip
Core tip: Gut microbes play important roles in fat storage and metabolism. The control of gut microbes is considered promising in the prevention of obesity. In this study, the regulatory effect of Ligustrum robustum aqueous extract (LR) on gut bacteria in vivo and in vitro and body weight was determined. Certain doses of LR prevented obesity without sacrificing daily food or energy intake. LR may affect the richness, diversity, and evenness of gut bacteria by increasing Lactobacillus and decreasing Enterococci in the host gut.
