The human body is made up of a few types of different fat. The first fat is called, structural fat, which cushions and protects the organs in the body. The body also has a fat called, normal fat, which is the padding on our body such as the padding on the feet and hands. Then the body has a fat called, abnormal fat, which is the excess fat on our bodies such as our love handles, spare tires, bellies, backs, and saddlebags.

When the hypothalamus is stimulated the body is able to release abnormal fat, which allows the body to rid itself of massive amounts of this type of fat very quickly. Dr. Simeons HCG diet protocol outlines a very low calorie diet (VLCD), in combination with HCG Activator. Dr. Simeons, through his research, concluded that an abnormally operating hypothalamus is a leading cause of obesity. When the hypothalamus is not operating correctly, it causes the body to have intense food cravings, constant hunger, low metabolism, and a surplus storage of abnormal fat.
