The HCG diet, created by Dr. Simeons, provides a combination of a very low calorie diet (VLCD), and minute levels of hCG (Human Chorionic Gonadotrophin) it needs to stimulate the hypothalamus. When the hypothalamus is stimulated the body is able to release abnormal fat which may be massive amounts of fat on some of us. When a person successfully completes the HCG protocol diet plan the hypothalamus is able to reset and function properly. 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.

hCG helps reset the hypothalamus which in turn regulates normal body functions including appetite control and proper burning of body fat. The hypothalamus functions as the main control center for the autonomic nervous system by regulating sleep cycles, body temperature, appetite, etc., and that acts as an endocrine gland by producing hormones, including the releasing factors that control the hormonal secretions of the pituitary gland.
