Recently in the news there has been a lot of discussion about HCG for weight loss. I have seen many advertisements and warnings in magazines of late, and Dr. Oz discussed it briefly on his show. He basically said “there might be something there, but more research needs to be done”.
HCG (human chorionic gonadotropin) is a hormone that pregnant women produce to release fat stores for the baby. In the 1950’s, a doctor by the name of A W Simeons successfully used HCG with a very low calorie diet to achieve weight loss in adolescent boys. The diet became popular in the 1970’s, fell out of favor, and then has regained popularity across the country since the 1990’s. We haven’t seen HCG much here in New York due to our restrictive prescribing laws.
The traditional use for HCG in doses of 15,000-20,000 IU has been used to treat infertility in women, because it can stimulate ovulation. Most of what we know about HCG is based on studies done in this setting, where it can cause premature failure of the ovaries. It is very difficult to find any studies done on the low doses we use for weight loss—500 IU/day for three weeks. Why? Well, it is impossible to do “long-term” studies on anything taken for only three weeks. Additionally, the dosage is so low over this short period of time it is difficult to discover the exact physiologic changes it produces. For those out there concerned about the safety of HCG, think of it this way: A pharmacist friend of mine once pointed out that men could take high doses of estrogen for three weeks and not suffer any long-term problems.
If that`s the case, then what are the problems? Problems from HCG diet programs stem from two issues. The first is if you are ordering HCG off the internet, you don`t really know what you are getting. HCG is a prescription medication, so if you are ordering it off the internet it is most likely is NOT HCG, but either the homeopathic version (which by definition contains none of the original molecules of the substance), or it has caffeine or other stimulants which can reduce hunger but have serious side-effects.
The second problem is the very-low calorie diet. It is physiologically unsafe for people to follow a 500 calorie-a-day diet without the use of medication like HCG that allows your body to release fat stores. The way HCG works is through resetting the hypothalamus to release those abnormal fat stores called adipose that our bodies have forgotten how to let go of. By using HCG, we can release 2000 cal/day from fat stores, so really our body is getting 2500 cal/day. If we just try to follow a 500 calorie diet we can suffer severe medical consequences like dizziness, lightheadedness and even collapse. These are made worse if a person has underlying medical problems.
HCG is a wonderful tool for weight loss. With medical supervision, HCG and a very low calorie diet can stimulate accelerated weight loss, and the ability to easily maintain that weight loss after the program is finished. It is quite different from other weight loss programs because it allows our bodies to release fat stores, so we burn mostly abnormal adipose fat and not the healthy structural fat or muscle. I am excited about adding this to our practice because of the health implications of losing fat-blood pressure decreases, blood sugar, insulin levels and cholesterol all decrease with weight loss. Everyone gains more optimal health through weight loss!
