ghrelin
- n a gastrointestinal hormone produced by epithelial cells lining the fundus of the stomach; appears to be a stimulant for appetite and feeding, but is also a strong stimulant of growth hormone secretion from the anterior pituitary
- Not only that, ghrelin may turn out to be one reason we feel hungry in the first place and why it's so hard for dieters to keep weight off.
- MC-4 is the neural gateway for ghrelin, leptin and up to 20 other chemicals.
- All this research confirmed ghrelin's role in driving appetite, both when we really need to eat and when we merely expect to.
