The term for fullness and satisfaction after eating is called what?

• A. Homeostasis
• B. Refractory period
• C. Set point theory
• D. Satiation

Answer: (D)

Satiation is the feeling of fullness and satisfaction that signals you to stop eating during a meal. As your stomach stretches and hormones like cholecystokinin (CCK) and other gut-brain signals rise, the brain interprets these cues and terminates the eating episode. This is the immediate process that ends a meal, distinct from satiety, which refers to the longer-lasting suppression of hunger after eating. Other terms don’t fit because they describe broader regulation (homeostasis), a different post-activity state (refractory period), or a theory about weight regulation (set point) rather than the moment you stop eating.
