Satiety
Satiety
Satiety (/səˈtaɪ.ɪ.ti/), from the Latin satis meaning "enough", is the state of being satisfactorily full and unable to take on more. It is the sensation of feeling full and the suppression of hunger for a period of time after a meal.
Definition
Satiety is the feeling of fullness and the suppression of hunger for a period of time after eating. It is a key concept in nutrition and weight management, as it helps to control the amount of food intake.
Physiology
The feeling of satiety is regulated by several hormones, including leptin, ghrelin, and insulin. These hormones interact with the hypothalamus, a region of the brain that plays a key role in controlling hunger and satiety.
Factors affecting satiety
Several factors can affect the feeling of satiety, including the volume and weight of food consumed, the type of macronutrients (proteins, fats, and carbohydrates) in the diet, and the individual's metabolic rate.
