I don't want to offend anyone, but I really don't get the HCG diet craze. I have many friends, acquaintances, and even clients who have done it, but it just doesn't make sense to me, and I think it is just a dangerous fad. HCG (human chorionic gonadotropin) is a hormone found in the urine of pregnant women that is supposed to suppress hunger and help utilize fat as a primary fuel source. The diet requires injections of the hormone or taking it orally with drops under your tongue.
The diet also calls for reducing your calorie intake to 500 calories per day! Who wouldn't lose weight eating only 500 calories a day? Maybe they should rename it the Auschwitz diet. A person who is experiencing such a drastic calorie deficit is also going to burn muscle if they are in starvation mode, and this problem is only compounded when they begin to decrease their physical activity level since they don't have enough energy to exercise.
I also think it is ironic that it's socially acceptable to inject yourself with these hormones in an attempt to change your physique, but doing so with steroids is looked down upon as cheating and is against the law. I need to do more research, but I haven't seen any studies that prove that the HCG injections are the magic ingredient for weight loss as opposed to just a starvation diet. Going on this kind of diet can mess up your metabolism. Once you go off the diet and start eating like you used to, you can expect the weight to return, so it is really not a long term solution.
If you are on HCG or have had good results from doing it, I wish you the best, but permanent weight control is a matter of developing long term sustainable healthy habits. How I feel about the HCG diet can best be summed up with a quote from Mickey Blue Eyes. "The first time I saw that Charles Manson on the news I said 'I know this guy's up to no good'."
