The cephalic phase occurs before the actual ingestion of food and involves the sensory stimulation of sight, smell, and taste of food, which triggers the release of insulin in anticipation of glucose absorption. The absorptive phase occurs after the ingestion of food and involves the absorption and use of nutrients as energy or storage. The fasting phase occurs when the body has finished absorbing nutrients and requires the breakdown of stored energy sources, such as glycogen and fat, to maintain energy metabolism.
