The hormone that makes you hungry is ghrelin.
Understanding Ghrelin: The Hunger Hormone
Ghrelin is often referred to as the "hunger hormone" because it plays a key role in signaling to your brain when you need to eat. Here's a breakdown of what ghrelin does:
- Release from the Stomach: Your stomach releases ghrelin when it's empty. This release acts like a message to your brain, indicating that it's time to find food.
- Signaling the Brain: Ghrelin travels to your brain and interacts with specific receptors. This interaction triggers a feeling of hunger, motivating you to eat.
- Beyond Hunger: While primarily known for its role in hunger, ghrelin has other functions as well:
- It signals the pituitary gland to release growth hormones.
- It plays a part in insulin release.
- It has a protective effect on your cardiovascular health.
Ghrelin's Role in Hunger Regulation
Ghrelin levels typically fluctuate throughout the day:
- They increase before meals, stimulating your appetite.
- They decrease after meals, helping you feel full.
This natural cycle ensures that your body receives the energy it needs while preventing overeating.
Summary
| Hormone | Main Function | Other Functions |
|---|---|---|
| Ghrelin | Signals hunger to the brain | Stimulates growth hormone release, impacts insulin, protects cardiovascular health |
In essence, ghrelin is a vital hormone that helps regulate your eating habits. It ensures that your body is properly fueled.
