Appetite
Appetite is the desire to eat food, felt as hunger. 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 and consummatory behaviours 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 anorexia nervosa, bulimia nervosa, cachexia, overeating, and binge eating disorder.

Famous quotes containing the word appetite:
“I wonder if his appetite was good?
Or, if it were, if also his digestion?
Methinks at meals some odd thoughts might intrude,
And conscience ask a curious sort of question,
About the right divine how far we should
Sell flesh and blood.”
—George Gordon Noel Byron (1788–1824)
“The quality of the will to power is, precisely, growth. Achievement is its cancellation. To be, the will to power must increase with each fulfillment, making the fulfillment only a step to a further one. The vaster the power gained the vaster the appetite for more.”
—Ursula K. Le Guin (b. 1929)
“When cafe life thrives, talk is a shared limberness of the mind that improves appetite for conversation: an adequate sentence maker is then made good, a good one excellent, an excellent one extraordinary.”
—Vivian Gornick (b. 1935)
