Scientists have known for a while that gut bacteria can play a profound role in the weight of mice. Now we have a case report in humans that is not entirely surprising: A woman gained 36 pounds and became obese in the 16 months after a fecal transplant.
…It’s impossible to draw conclusions from any single patient, of course, but this case is interesting against the broader context of what we know about the gut microbiota and weight. A decade of studies in mice have found that those implanted with the gut microbiota of obese humans will become obese, too, despite eating the same diet as those given the microbiota of non-obese humans. Gastric bypass surgery in mice also drastically shifts the gut microbiota, and it could be one reason for why the surgery is so effective for losing weight.
