Binge-eating disorder is characterized by recurrent episodes of eating large amounts of food in a discrete period, accompanied by a sense of loss of control, and followed by distress. Unlike bulimia, the binges are not regularly compensated by purging, fasting, or excessive exercise.

Episodes often occur in private and are marked by eating more rapidly than normal, eating until uncomfortably full, and eating large amounts when not physically hungry. Guilt, disgust, and depression commonly follow. The disorder is associated with overweight and obesity, yet it is distinct from them; many people with obesity do not binge, and some people of normal weight do. It is the most common eating disorder in many population studies.

Risk factors include dieting history, negative affect, and certain impulsivity traits. Treatment approaches with evidence include cognitive-behavioral therapy, interpersonal psychotherapy, and, in some cases, medication. The goal is to restore regular eating patterns, reduce the frequency of binges, and address the emotional triggers that precede them.

Binge-eating disorder is not a failure of willpower. It is a recognized psychiatric condition that responds to appropriate intervention.
