Obesity and Gut Bacteria

Research suggests gut bacteria may influence weight.
The Los Angeles Times (6/21, Dance) reports, "Between 10 trillion and 100 trillion microbes, mainly bacteria, dwell in a person's colon and small intestine." Recently, "researchers have discovered significant links between gut bacteria and weight and metabolism in mice -- and are starting to find similar associations in people." Yet, the "story in humans is far from certain, though, and scientists say it's too soon to concoct microbe-filled 'stay-slim' beverages -- a fact that has not prevented some companies from promoting their bacteria-laden products as helpful for weight loss."
