The Hunger Games: How Hormones Control Your Appetite

Have you ever wondered why you feel hungry or full? The answer lies in the complex world of hormones that regulate your appetite and satiety. In this article, we’ll delve into the fascinating world of hunger hormones and explore how they impact your eating habits.

Ghrelin: The Hunger Hormone

Ghrelin is often referred to as the “hunger hormone.” Produced mainly in the stomach lining, ghrelin stimulates appetite, increases food intake, and promotes fat storage. Levels of ghrelin rise every four hours after meals and drop after eating.

Leptin: The Satiety Hormone

Leptin, on the other hand, is produced by fat cells and sends signals to the brain to suppress appetite. Leptin regulates energy metabolism and controls food intake over the long term.

Other Hormones That Regulate Appetite

Several other hormones play a crucial role in regulating appetite and satiety, including:

1. Amylin: Delays stomach emptying and lowers blood glucose.
2. Cholecystokinin: Suppresses hunger and stimulates gallbladder secretion.
3. Corticotropin-releasing factor: Reduces appetite.
4. Dopamine: Enhances pleasure from food and triggers cravings.
5. Glucose-dependent insulinotropic polypeptide: Stimulates insulin release.
6. Glucagon-like peptide: Slows stomach emptying and suppresses appetite.
7. Glucagon: Increases satiety.
8. Insulin: Reduces blood glucose and stimulates fat storage.
9. Neuropeptide: Stimulates appetite.
10. Oxyntomodulin: Suppresses appetite and slows stomach emptying.
11. Pancreatic polypeptide: Slows stomach emptying.
12. Peptide YY: Gives a feeling of fullness and slows stomach emptying.
13. Serotonin: Provides a feeling of relief after eating sugary foods.
