A person with a binge-eating disorder consumes a large amount of food within two hours, and does it often. Having a binge eating disorder means being unable to control the amount of food consumed. You are unable to stop eating, even when you are full.
Most of us overeat from time to time, and many people often feel they've eaten more than they should have. But, does this mean we are "binge eaters?" Probably not: Eating a lot of food does not always mean that a person has an eating problem.
About 2% of all adults in the U.S. (as many as 4 million Americans) have binge eating disorder. About 10% to 15% of people who are mildly obese and who try to lose weight on their own or through commercial weight-loss programs have this condition. The disorder is even more common in people who are severely obese.
No one knows for sure what causes binge eating disorder, but there are several factors that are thought to contribute. Genetics and biology seem to play a role in the development of the disease. Researchers are actively studying how the abnormal functioning of brain areas that regulate hunger and fullness, or impulse control can contribute to binge eating. Individual psychology is also thought to play a role: about 50% of people with binge eating disorder suffer from depression, and it is thought that negative emotions -- anxiety, shame, and guilt -- contribute to out-of-control eating behaviors. Social and cultural factors also likely play a role in binge eating disorder, as food can become a way to show love, get comfort, or even induce guilt. The food industry and wide availability of processed foods can make it more difficult to be in tune with what will nourish our bodies. As well, Western culture emphasizes a desire for thinness. Many people with binge eating disorder have been on multiple diets.
