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:

    Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtue’s effect, not its substance.
    Thomas Aquinas (c. 1225–1274)

    Society is composed of two great classes—those who have more dinners than appetite, and those who have more appetite than dinners.
    —Sébastien-Roch Nicolas De Chamfort (1741–1794)

    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)
