Submission + - Study: microbiome changes drive the dieting yo-yo effect
wheelbarrio writes: We've known for a long time that diet-induced weight loss is rarely permanent but until now what has been a frustration for dieters has also been largely a mystery to science. A paper published today in the prestigious journal Nature presents good evidence that your gut microbiome may be to blame. Studying mice fed cycles of high-fat and normal diets, the authors find that the particular bacterial population that thrives in the high-fat regime persists in the gut even once the mice have returned to normal weight and normal metabolic function after a dieting cycle. This leaves them more susceptible to weight gain than control mice who were never overweight, when both populations are exposed to a cycle of high-fat diet. The details are fascinating, including the suggestion that dietary flavonoid supplementation might mitigate the effect. My guess is that this may end up being one of the most cited papers of the year, if not the decade.
