Could another person's feces help you lose weight?

  • A study links increased diversity of fecal bacteria with lower levels of fat
  • Scientists are looking into whether fecal transplants could help weight loss

(CNN)The diversity of the bacteria living in your feces is linked to how much fat you have in your body, according to a new study.

The insight could pave the way for fecal transplants of bacteria to help people manage their weight, reduce their risk of certain metabolic diseases or, more simply, encourage them to broaden the bacteria found in their gut -- and therefore their poop -- by eating a healthier, more varied diet.
"We wanted to characterize how the microbiome changes in obese people ... and see which bacteria live in the gut," said Michelle Beaumont, a research associate in gut microbiome and obesity at Kings College London, and lead author of the study. "This study has shown a clear link between bacterial diversity in feces and markers of obesity and cardiovascular risk."
