The hormone that tells you to stop eating is leptin.
Leptin is produced by fat cells and acts on the hypothalamus, a part of the brain that controls appetite. When you eat, your fat cells release leptin, which signals to your brain that you are full and should stop eating.
Leptin also plays a role in regulating energy expenditure and metabolism.
While leptin is a key hormone in regulating appetite, other factors also influence your hunger and satiety, such as:
- Ghrelin: This hormone is produced in your stomach and stimulates your appetite.
- Insulin: This hormone is produced by your pancreas and helps regulate blood sugar levels. It also plays a role in satiety.
- Cholecystokinin (CCK): This hormone is released in your gut and helps you feel full after eating.
It is important to note that leptin resistance, where the brain does not respond properly to the hormone, can contribute to weight gain and obesity.
