What condition is characterized by excessive or insatiable appetite?

The condition characterized by excessive or insatiable appetite is best matched with binge eating. Binge eating disorder involves consuming large quantities of food in a short period while feeling a lack of control over eating. Individuals with this disorder often experience significant distress and may use food as a coping mechanism for emotional issues.

In contrast, anorexia is characterized by an intense fear of gaining weight and a distortion of body image, leading to restricted food intake. Bulimia involves episodes of binge eating followed by compensatory behaviors such as vomiting or excessive exercise, but the hallmark of excessive appetite is more accurately pointed to binge eating itself. Obesity denotes an excess amount of body fat and can result from a combination of genetic, environmental, and psychological factors, but it does not directly describe the behavior of insatiable appetite.
