Satiety is the feeling of fullness that occurs after eating, signaling to the body that it has had enough food. This sensation helps regulate food intake and prevents overeating. Various factors, including the type of food consumed, portion size, and individual metabolism, can influence satiety levels. Hormones play a significant role in satiety. For example, leptin is a hormone produced by fat cells that helps signal to the brain when to stop eating. Additionally, fiber-rich foods, such as fruits and vegetables, can enhance satiety by slowing digestion and promoting a longer-lasting feeling of fullness.
