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.
