L.T.
I have had two family members that have done HCD Diet. One very sucessfully and one not. You have to be able to follow the diet to the letter. It is very extreme!! They both did it with strict doctors supervision. Please do not buy HCG online. Victoria mentioned Dr. Oz site - I taped the show he did on it and it was very informative!! One diet that I have tried and I feel is completely managable with my life style is the 17 day diet.
Good Luck!
