Gut Bacteria Influence Diet Success: Study

Your gut bacteria may determine how successful you are when trying to lose weight, a new study says.

It included 62 overweight people in Denmark who ate either a low-fat diet high in fiber, fruits and vegetables and whole grains, or a typical diet for 26 weeks, The New York Times reported.

In the high-fiber group, those with a high ratio of Prevotella to Bacteroides gut bacteria lost an average of 10 pounds of body fat, three and a half pounds more that those with a low ratio, according to the study in The International Journal of Obesity.

In the typical diet group, those with a high ratio lost four pounds, compared with five and half pounds for those with a low ratio. That difference was statistically insignificant.

"This finding is something that could really be used," said study lead author Mads Hjorth, an assistant professor at the University of Copenhagen, The Times reported.

"You can't go and get this done now, but within a reasonable amount of time it might be a possibility," he added.
