Why you START & STOP Eating - Ghrelin Function?

You start and stop eating because your body has a special signal called ghrelin that tells you when to be hungry or full.

Imagine your tummy is like a little robot inside you. When it’s empty, it sends a message: “Hey, I need food!” That message is ghrelin, and it makes you feel hungry, just like when your snack time arrives at school, and you can’t wait to eat your favorite treat.

How Ghrelin Works

When you finish eating, your tummy says, “I’m full,” and the signal stops. It’s like when you finish a big lunch and suddenly don’t want any more cookies, your body knows it’s had enough!

But when your tummy is empty again, like after a long day at school, ghrelin starts working again, and you feel hungry once more, just like how your robot tummy wants to eat again.

So, ghrelin is the little helper that tells you when to start eating and when to stop, kind of like a timer in your stomach!
