Some people compare binge eating to an addiction.
Adherents of the theory point to the high concentration of carbohydrates in the foods people are most likely to binge on. They also site biochemical changes in the binger's blood. Professor Kelly Vitousek disputes the notion of food addiction. The increased insulin level observed in binge eaters is as likely to be a result of overeating as it is to be the cause. Be skeptical of reports that confuse binge eating with obesity.
