What is hCG and how does it result in rapid weight loss?

hCG stands for Human Chorionic Gonadotropin, a hormone present in both men and women, but which is produced in great amounts in pregnant females.  During pregnancy, the substance almost completely controls the woman’s metabolic functions.  In non-pregnant persons, research suggests hCG similarly increases the metabolism similar to a pregnant female.  Thousands of calories in stored fat are released, and are used by the body or expelled.    To keep the fat cells from immediately taking in more fat, the very low fat VLCD is necessary and personal care products such as lotion, are prohibited.
