Overeating occurs when an individual consumes more calories in relation to the energy that is expended via physical activity or expelled via excretion, leading to weight gain and often obesity. Overeating is the defining characteristic of binge eating disorder.^[1]

Overeating can be a symptom of binge eating disorder^[2] or bulimia nervosa.^[3]

In a broader sense, hyperalimentation includes excessive food administration through other means than eating, e.g. through parenteral nutrition.

Treatment

Cognitive behavioural therapy, individual therapy, and group therapy are often beneficial in helping people keep track of their eating habits and changing the way they cope with difficult situations. Often overeating and the related binge eating are related to dieting, body image issues, as well as social pressures.^[4]

There are several 12-step programs that helps overeaters, such as Overeaters Anonymous or Food Addicts in Recovery Anonymous and others. It is quite clear through research, and various studies that overeating causes addictive behaviors.

In some instances, overeating has been linked to the use of medications known as dopamine agonists, such as pramipexole.^[5]
