Scientists have uncovered a brain-stomach connection that may help explain why we crave food and keep eating even when we're full.
Featured in the journal Science, this study of hungry volunteers revealed specific brain activity linked to the anticipation that a good meal is on the way. When the stomach is full, that brain activity slows down, like a brake that helps a person avoid overeating. Researchers say people with certain eating disorders may have a faulty brake system, and may not get the message to slow down when they are full.
Researchers say the findings may help lead to a better understanding of eating disorders and could lead to behavior modification strategies to help re-train the brain's food craving center.
The research was conducted at the Institute of Neurology in London and is published in the journal Science, published by AAAS, the Science Society.
