Human Chorionic Gonadotropin (hCG) is a hormone made by the body during early pregnancy, and this diet is named after it. Proponents of this diet claim that if you follow a very low calorie diet, your metabolism will be reset by hCG to help you lose 1 lb. or more a day without being weak or hungry. Science agrees that eating a very low calorie diet will help you lose weight. However, research has shown no connection between weight loss and hCG.
