The appetite is the desire to eat food, felt as hunger.
Appetite is regulated by a close interplay between the digestive tract, adipose tissue and the brain.
Decreased desire to eat is termed anorexia, while polyphagia (or "hyperphagia") is increased eating.
Disregulation of appetite contributes to anorexia nervosa and cachexia, or oppositely, overeating.
