Blocking Ghrelin Possible Key to Weight Loss in some Ethnic Groups
Ghrelin is a hormone released by the stomach that causes you to feel hungry. After eating, ghrelin levels fall back to normal. In a recent study it was found that after black women ate their ghrelin levels tended to stay higher than white women - this could trigger weight gain. The higher ghrelin levels were associated with elevated 24-hour cortisol levels in black women also. Cortisol is a stress hormone and elevated levels are connected to obesity and diabetes. The study appears in the September 2004 issue of the Journal of Clinical Endocrinology and Metabolism.

On July 12th we reviewed a study showing that soy Isoflavones at a dosage of 114mg per day lowered ghrelin levels significantly. Perhaps soy Isoflavones is a tool for loosing weight.
