AI overview
Appetite is the desire to eat food, typically driven by hunger, though appealing foods can trigger it even when you're not physically hungry. It matters because it helps regulate how much energy your body takes in to meet its metabolic needs, and it's controlled by a complex interaction between your digestive system, fat tissue, and brain.

thumb|Appealing food may provoke appetite even in the absence of hunger. Appetite is the desire to eat food items, usually due to hunger. Appealing foods can stimulate appetite even when hunger is absent, although appetite can be greatly reduced by satiety. Appetite exists in all higher life-forms, and serves to regulate adequate energy intake to maintain metabolic needs. It is regulated by a close interplay between the digestive tract, adipose tissue and the brain. Appetite has a relationship with every individual's behavior. Appetitive behaviour also known as approach behaviour, and consummatory behaviour, are the only processes that involve energy intake, whereas all other behaviours affect the release of energy. When stressed, appetite levels may increase and result in an increase of food intake. Decreased desire to eat is termed anorexia, while polyphagia (or "hyperphagia") is increased eating. Dysregulation of appetite contributes to ARFID, anorexia nervosa, bulimia nervosa, cachexia, overeating, and binge eating disorder.
==Role in disease== A limited or excessive appetite is not necessarily pathological. Abnormal appetite could be defined as eating habits causing malnutrition and related conditions such as obesity and its related problems.
