The physiological and psychological feeling of fullness and satisfaction that occurs after eating, which leads to the cessation of food intake. Satiety is regulated by a complex network of signals between the digestive tract, adipose tissue, and the brain. Key hormones involved include leptin, which provides long-term energy balance signaling, and short-term signals like peptide YY (PYY) and cholecystokinin (CCK).
Refined carbohydrates are notoriously poor at inducing satiety because they are digested quickly and fail to trigger the same hormonal responses as protein and healthy fats. A diet high in protein and fiber-rich vegetables enhances satiety, making it easier to control caloric intake naturally without the need for willpower-based restriction.
