An imbalance of gut bacteria might potentially lead to weight gain. Gut bacteria play an important role in a variety of bodily functions, including digestion and metabolism.
Changes in the composition of bacteria in the gut may affect the body’s ability to digest food and absorb nutrients properly.
In addition, changes in the makeup of gut bacteria have been linked to various mechanisms contributing to overweight and obesity.
Maintaining a healthy balance of gut bacteria through diet, exercise, and potentially probiotic supplementation might help prevent weight gain and promote overall health (2).
