ST. LOUIS, Mo. --The bacteria in your gut could be making you fat. A recent study finds the bacteria we all have in our intestines may be a cause of weight gain, and our westernized diet is making things worse.Researchers at the Washington University School of Medicine in St. Louis transplanted human microbes into mice. When the animals were taken off a low-fat diet to one made up of high fat and sugars, the microbial makeup of the mice changed within 24 hours. The mice soon became fat.
Scientists stress that there are many factors that play a role in weight gain, but this discovery may help scientists have a better understanding and perhaps treat the problem of obesity around the globe.
