Human Chorionic Gonadotropin, also known as hCG, is a hormone naturally producted by the body. It has many functions and is used medically in both male and females. For use of weight loss, based on the research developed by Dr. A.T.W. Simeon. HCG effects the Hypothalamus, in the brain, to signal release of stored fat into the bloodstream. This released fat is used to provide energy and decrease appetite. This process prevents the breakdown of fats that are essential in normal healthy people, such as intramuscular fat, fat around vital organs, and fat around blood vessels. This is especially effective in a low-calorie diet, because the body will break down fat regardless of its location.
