Now this is interesting!! Microbes certainly play a very important role in health. But weight?
We all carry a few pounds' worth of microbes in our gut, a complex ecosystem collectively called the microbiota. The endotoxin, Dandona suspected, originated in this native colony of microbes. Somehow, a greasy meal full of refined carbohydrates ushered it from the gut, where it was always present but didn't necessarily cause harm, into the bloodstream, where it did. But orange juice stopped that translocation cold.
Dandona's ongoing experiments—and others like it—could upend much of we thought we knew about the causes of obesity, or just that extra pesky 10 pounds of flab. If what some scientists now suspect about the interplay of food and intestinal microbes pans out, it could revolutionize the $66 billion weight loss industry—and help control the soaring $2.7 trillion we spend on health care yearly. "What matters is not how much you eat," Dandona says, "but what you eat."
