Eat to Boost Your Gut Bacteria
"There are interesting preliminary studies evaluating probiotics for their relationship to obesity," says Dr. Raj adding, "although we don't have all the information yet, I don't think it's a bad idea to try to add more probiotics into your diet." She says to skip the probiotic pills and instead opt for eating more fermented foods like kimchi, sauerkraut, and cultured milk products, like yogurt and kefir.
In a September, 2013 article published in Science, researchers took fecal samples from twin sets of mice where one twin was normal and the other was obese. The researchers transplanted the gut bacteria from both the lean and the obese mice and into "sterile" mice. The mice that had received the fecal transplants from the obese twins started gaining weight and showing symptoms of obesity within days. Humans aren't mice, and more research needs to be done, but scientists are beginning to believe that gut bacteria may have a direct relationship to overall metabolism, and that boosting your good gut flora could help you burn more calories all day, every day.
