Bugs in the gut can cause obesity: study

CHICAGO (AFP) - The bugs that help digest food may also cause the body to pack on the pounds if they are not properly regulated, a new study has found.

That is because if the wrong kinds of bacteria take over they can cause a low-level inflammation that leads to a pre-diabetic condition and an elevated appetite, the study published Thursday in the journal Science found.

“It has been assumed that the obesity epidemic in the developed world is driven by an increasingly sedentary lifestyle and the abundance of low-cost, high-calorie foods,” said senior author Andrew Gewirtz of Emory University School of Medicine.

“However, our results suggest that excess caloric consumption is not only a result of undisciplined eating but that intestinal bacteria contribute to changes in appetite and metabolism.”
