I have heard this too, and yet people keep coming back for "another round" of HCG. Personally I don't buy it, and coming from a medical background I don't believe it's possible to absorb enough HCG orally to do much of anything. I think it works because people "Believe" it works. It's a placebo effect. I think HCG diets are medically sanctioned anorexia. You can't deny anorexia works, doesn't mean it's a good idea. That's just my opinion, and I try very hard to stay off the HCG posts because I know if I read them I'll just get pissed off and post something not so nice
