...how safe this is...yes it's a hormone your body has naturally during pregnancy, but during pregnancy there are several things that keep this hormone in check. I have attended many obesity medical conferences and to date, I have never heard of a certified bariatric medical doctor ever recommending this diet as a treatment. I'd tread with extreme caution. At a recent breast/gyn conference, a well respected oncologist in our area raised serious concerns about this diet...for crying out loud, HCG in a nonpregnant person is often tested as a tumor marker! Of course, one of the diet's biggest proponents only makes me more skeptical-a patient asked me to read his book and I raised more red flags and had more questions and concerns after reading the book. I for one will never risk my DEA license to prescribe or recommend something this dangerous. Sure, there have been far too many instances where FDA approved drugs have caused harm, however these drugs have been studied and the problems identified...I have yet to find any placebo controlled double blind studies done with this diet...
just my opinion
