Could the germs in your gut help you lose more weight?

Weight-loss surgery is meant to help you lose weight after trying everything imaginable. New research finds that it’s not only about the surgery, but about the germs in your stomach that help you lose more pounds.

People with higher levels of certain methane-producing microbes in their gut could lose more weight, according to the study. These germs are called methanogens and were measured through the breath of 150 patients participating in the study.
