This work presents the effects of the high-fat diet (H) consumed by the progenitor (G0) on cardiometabolic disorders and intestinal microbiota in the second-generation offspring (F2). The rats submitted to H (G0H) or control (C) (G0C) diets, during mating, gestation and lactation, generated F2 offspring (F2-G0H and F2-G0C, respectively), which received only the C diet. Both, G0H and F2-G0H, showed changes in the intestinal microbiota, increased MAP, plasma TAG levels, adiposity index and the inflammatory process in retroperitoneal fat and in the colon shown by increased TNF-α, MCP-1, MyD88 and CAV-1 gene expression. In addition, F2-G0H showed increased food intake, leptin resistance, total cholesterol and plasma levels of MCP-1 and reduced adiponectin. Regarding microbial communities, a greater diversity was observed in 5 unique families of bacteria that was correlated with cardiometabolic disorders. Overall, progenitors with cardiometabolic disorders induce an increase in food intake, systemic inflammation and microbiota alterations in the F2-G0H offspring.
