​The HCG hormone kicks up the metabolism, by signaling the body to burn more fat. Following the HCG diet protocol your metabolism with operate over 30%--a much more efficient level to burn, rather than store. In other diets the metabolism has not changed, and following the diet will continue to run at the same rate, which in most of us dieters has been found to be at only 8%. HCG opens only the excess fat cells allowing excess fat to be burned. No other time in the human body does this happen, and so other diets often remove fat cells the body needs, causing us to lose in places we don't want to first, and finally where you need it. HCG burns the excess fat cells taking the needed fat, and literally sculpting the body, losing inches as well as pounds.
