Gallic acid prevents obesity in mice on a high-fat diet via the gut microbiota-adipose tissue axis.

ABSTRACT: Obesity is closely related to the gut microbiota, and gallic acid (GA) has anti-obesity properties, but its relationship with the gut microbiota is unclear. The aim of this study was to investigate the role of gut microbiota in the anti-obesity mechanism of GA by fecal microbiota transplantation (FMT). Here, we found that high-fat diet (HFD) promoted lipid deposition and gut microbiota dysbiosis in mice, whereas GA slowed down lipid deposition and restored gut microbiota dysbiosis and its functional profile, as evidenced by the reduction of the obesity-causing bacterium Desulfovibrio and the enrichment of the beneficial bacterium Lachnospiraceae_NK4A136_group, Clostridiales_unclassified, Oscillospira and Adlercreutzia. These gut microbiota and metabolites
