Binge eating disorder (BED), is a psychiatric disorder in which a subject shows the following symptoms:
* Periodically does not exercise control over consumption of food.
* Eats an unusually large amount of food at one time—more than a normal person would eat in the same amount of time.
* Eats much more quickly during binge episodes than during normal eating episodes.
* Eats until physically uncomfortable and physically feels like they're on the verge of throwing up due to the amount of food just consumed.
* Eats when depressed, sad, or bored.
* Eats large amounts of food even when not really hungry.
* Usually eats alone during binge eating episodes, in order to avoid discovery of the disorder.
* Often eats alone during periods of normal eating, owing to feelings of embarrassment about food.
* Feels disgusted, depressed, or guilty after binge eating.
