It is also considered to be a form of a obsessive-compulsive disorder such that it reflects a "reward deficiency syndrome" that is thought to be due, in part, to a reduction in D2 receptors. .
On a psychological aspect, one may engage in overeating when in response to a conflict, emotional distress, or is just simply bored. However, overeating is mostly used as a coping method. According to Neumark-Sztainer (1998), overeating usually starts in early childhood when eating patterns are formed. Most people who become compulsive eaters are people who possibly never learned the proper way to deal with stressful situations and used food instead as a way of coping.
As mentioned earlier, it may also be considered a form of obsessive-compulsive disorder due to the fact that one may not be able to stop eating voluntarily. Also, once a person has negative feelings for having eaten so much, the person may resort to more eating, since they either cannot stop, or have eaten so much already it wont matter. Ironically however, the more weight that is gained, they do in fact try harder to diet yet dieting is usually what leads to the next binge, which can be followed by feelings of powerlessness, guilt, shame and failure This cycle only resorts to a repetitive pattern that can go on "forever" if the emotional reason for the overeating is not dealt with.
The sociological view explains that overeating may particularly be due to protection, especially to rape victim survivors who sometimes feel that being overweight will keep others at a distance and make them less attractive (Medvalet, 1995). They may also explain it in terms of coping from environmental factors such as stress in the workplace. Socioeconomic factors may play a part as well, such that those with higher socioeconomic resources may have better access to facilities to better health, such as fitness gyms and customized diet programs. .
