Definition


Appetite is the sensation felt when one is hungry, and which gives the desire to eat. It is a natural need that may be provoked by visual or olfactory stimuli, and is controlled by two hormones, leptin and ghrelin. An appetite leads an individual to eat, thus nourishing the organism by bringing it energy to function. Appetite varies according to the person. Anorexia is characterized by a loss of appetite. Bulimia, on the other hand, generates a very strong appetite.
