Ingestive behaviors : ウィキペディア英語版 | Ingestive behaviors
Ingestive behaviors encompass all eating and drinking behaviors. These actions are influenced by physiological regulatory mechanisms; these mechanisms exist to control and establish homeostasis within the human body. Disruptions in these ingestive regulatory mechanisms can result in eating disorders such as obesity, anorexia, and bulimia. Research has confirmed that physiological mechanisms play an important role in homeostasis; however, human food intake must also be evaluated within the context of non-physiological determinants present in human life. Within laboratory environments, hunger and satiety are factors that can be controlled and tested. Outside of experiments though, social constraints may influence the size and number of daily meals. ==Initiating ingestion== Body weight regulation requires a balance between food intake and energy expenditure. Two mechanisms are required to maintain a relatively constant body weight: one must increase motivation to eat if long-term reservoirs are being depleted, and the other must restrain food intake if more calories than needed are being consumed.
