In the human body, the hypothalamus gland is a critical bridge between the endocrine system (hormonal system) and the nervous system. Located right at the center of the brain, the hypothalamus regulates many of the body’s autonomic functions including internal temperature, body weight, sleep, saline balance, and the emotions.
In particular, the hypothalamus regulates hunger and thirst while playing a substantial role in the body’s overall metabolic rates. For this reason, much attention has been paid to the hypothalamus gland as a potential target for promoting lasting weight loss. If the brain and body can be retrained to reduce the body’s fat reserves and overall body weight via the hypothalamus, then we could enjoy long-lasting weight reduction.
One popular diet introduced by Dr. A.T.W. Simeons in the 1950’s seeks to “retrain” the hypothalamus through what he called the HCG Diet after the human chorionic gonadotropin hormone, a chemical he found to trigger fat metabolism among mothers following childbirth. Substantial questions about the effectiveness and indeed the safety of this diet exist, though it has continued to be popular despite the need for expensive injections or oral drops of the hormone to be taken as part of the diet.
