HCG stands for human chorionic gonadatropin. It is a hormone that is produced in large quantities in pregnancy (both men and women have male and female hormones, so this program is just as successful for men).
HCG is responsible for making the abnormal fat reserves of the body available to be burned as fuel. In pregnancy it is used to protect the nutritional health of the growing baby, however, in conjunction with this program it is used to rid the body of abnormal fat deposits. Rest assured that the HCG helps to stave off any hunger pangs that a restricted diet may cause. With the introduction of HCG, thousands of extra calories being to flood the system from the abnormal fat being metabolized. For this reason, HCG diets are easier to stick to than a traditional healthy diet that simply restricts calories. When a program is easy to stick to, success is the end result!
Research in the 1950s resulted in concluding that there are three different types of fat stored in the body:
Structural (visceral) Fat: Fat in and around muscles, cushioning organs, padding on bottoms of feet, etc.
Normal Fat: Dermal fat which is directly under the skins surface and provides the soft cushioning between the skin and frame of the body.
Abnormal (adipose) Fat: Fat under the dermal fat and not available for use by the metabolism until the other 2 kinds of fat are reduced.
Abnormal fat can be viewed as "famine fat". It is stored in the body for emergency famine. Yo-yo dieting contributes to the storage of this type of fat because the body begins to question the availabilty of fuel (food). When calories are restricted, the body stores all the fat it can, to save up for the lean times! Research produced a plan that results in an average weight loss of .5 to 1lb a day of Abnormal fat when accompanied by a VLCD (very low calorie diet).
Most calorie reduction diets will not produce the best results for those individuals with an abundance of Abnormal fat stores because their bodies will begin by burning the wrong kind of fat. When a low calorie diet is introduced to the system, the Normal reserves of fat are used up first. As a reult, most people look gaunt and drawn after a reduced caloric diet. Although the normal reserves of fat have been reduced, the abnormal fat remains intact. Without using HCG in a reduced calorie diet plan, the body will burn Structural and Normal fat.
HCG works to release the Abnormal fat stores and make them available to be used as fuel. By following the protocol precisely the body will "burn" the Abnormal fat, while preserving muscle, normal fat, and structural fat.
