Studies showed that a person’s diet and their gut microbes interact and affect obesity. There is a difference between the gut microbes of a lean person and an obese person. An obese person has less-diverse microbial communities, compared to a lean person. However, a person’s gut microbes depend on his/her diet. Having a healthy diet (high in fiber, low in saturated fats) produces and encourages more lean gut microbes, which means that this can prevent or lessen obesity.
