Studies suggest that gut bacteria may play a powerful role in body weight regulation. Some animal studies also show that when gut bacteria from mice with obesity were transplanted into the guts of lean mice, the lean mice developed obesity ( 17). What’s more, those with obesity who have less diverse gut bacteria tend to gain more weight than people with obesity who have more diverse gut bacteria ( 11, 16). People with obesity tend to have less diverse gut bacteria than lean people. However, several studies have failed to find a connection between the firmicutes-to-bacteroidetes ratio and obesity ( 15). In the majority of those studies, people with obesity had more firmicutes and fewer bacteroidetes, compared with moderate-weight people. Body weight seems to be related to the balance of these two families of bacteria ( 9, 10).īoth human and animal studies have found that moderate-weight people have different gut bacteria than those with overweight or obesity ( 11, 12, 13, 14). There are two main families of good bacteria in the gut: bacteroidetes and firmicutes. They also help break down fiber, which your body can’t digest, turning it into beneficial short-chain fatty acids like butyrate ( 8). The majority of these are friendly bacteria that produce several important nutrients, including vitamin K and certain B vitamins. Hundreds of microorganisms reside in your digestive system.
