"New research suggests the mix of microbes in our guts can either help — or hinder — weight-loss efforts.
"We started with the premise that people have different microbial make-ups, and this could influence how well they do with dieting," explains Purna Kashyap, a gastroenterologist at the Mayo Clinic in Rochester, Minn.
As part of the study, Kashyap and his collaborators tracked the progress of people who were enrolled in a lifestyle-intervention program for weight loss. The participants were advised to follow a low-calorie diet, and they were tracked closely for about three months.
"We found that people who lost at least 5 percent of their body weight had a different gut bacteria as compared to those who did not lose 5 percent of their body weight," Kashyap explains. Their findings are published in the journal Mayo Clinic Proceedings."

"The successful dieters had an increased abundance of a bacteria called Phascolarctobacterium, whereas another bacteria, Dialister, was associated with a failure to lose the weight. And, Kashyap says it's likely that there are other types of bacteria that might influence dieting as well."
Bottom line: the bacteria eat what else can't
"Probiotics that are currently on the market would not be effective. The idea is to develop a new product that includes the specific types of bacteria linked to successful dieting.
But it's not so simple to manipulate the mix of microbes in our guts. Identifying the organism — or organisms — that are thought to be beneficial is just the first step."
