Ghrelin, the Hunger Hormone

A hormone with which the body controls hunger. When you are low on energy, the body uses it to make you hungry. Then, when you are sated, the body withdraws it. If this were available in pill form, taking them would keep us hungry and eager to eat, eventhough your stomach is full. Ideal for overeating and gaining fast.

Megestrol, Fattener Medication

This medication is used to make people eat that normally would not be hungry. I wonder how it works with normal people or even fat people.
