In recent decades, overweight and obesity have become a growing health problem. The main risk factors include increased fat intake and exposure to stressful situations. In the last years, gut microbiota (GM) has become increasingly important, contributing to the regulation of energy homeostasis. It has been described that stress and diet could alter the composition of GM, causing dysbiosis and increased intestinal permeability, inducing inflammation. In this context, the aim of this work was to investigate the relationship betweenhigh-fat diet (HFD) and chronic exposure to environmental stressors in metabolism, composition of the gut microbiota and histological alterations in liver and small intestine. The investigation was carried out in male C57Bl/6J mice consisting of four experimental groups (n=7): mice fed a normal diet (ND), DN+chronic stress (CS), high-fat diet (HFD) and HFD+CS. We observed a significant increase.in body weight, fasting blood glucose and blood glucose overload test in mice fed HFD (p
