Wonder why you can't stop eating sweets? The University of Toronto researchers think they know why. The gene variation may make it hard for the body to sense blood sugar changes, so the brain doesn't get the signal to stop eating. In a new study, people with a genetic quirk drank 44 percent more sugary drinks, ate 34 percent more sweets and consumed 100 to 200 more calories a day from the extra sugar. It's not a surprise these people weighed more and had bigger waists. So far no remedy for this issue but try carefully counting your overall calories so you have room for an occasional slice of heaven.
