Final answer:
Satiation is the body's physiological response to eating an adequate amount of food. It is regulated by several mechanisms including the increase in blood glucose levels and the release of leptin, a satiety hormone.
Step-by-step explanation:
The body's physiological response to eating an adequate amount of food is known as satiation. Satiation is regulated by several physiological mechanisms. Once a person has eaten, blood glucose levels increase and signals are sent from the pancreas and liver to shut off hunger and eating. The food's passage through the gastrointestinal tract also provides satiety signals to the brain, and fat cells release leptin, a satiety hormone.
