Psychological and physical stress in animals and humans has been shown to alter feeding behavior. Both the type and the duration of the stressor appear to play a role in determining the effect on food intake. In laboratory animals, some stressors, e.g., mild tail pinching, will lead to overeating, while other stressors, e.g., immobilization stress or exposure to a novel environment, result in anorexia.1 In a study conducted in humans, we found that 44% increased eating and 48% decreased eating when stressed,2 Pathological stress overeating can also be precipitated by stress, as seen in bulimia, in which the eating binge tends to be precipitated by a traumatic event occurring during a period of voluntary dieting.3 Anorexia nervosa may be considered a pathological form of stress-induced undereating.
