1. A ravenous or insatiable appetite for food.
2. An eating disorder marked by rapid consumption of large amounts of food, often of minimal nutritional value, in a short period of time.

Such eating, or binge eating, is typically episodic and recurrent, accompanied by an awareness that such overeating is abnormal, by fear that eating cannot be stopped voluntarily, and by a depressed mood and self-deprecating thoughts after each binge.

Each binge is usually terminated by abdominal pain, induced vomiting, or a social interruption of the secret eating pattern.
