HCG Diet doesn't work.. What happens is the HCG makes you produce more testosterone, and the 500 kcal/day makes you loose weight..

Quote:

There is no scientific evidence that HCG is effective in the treatment of obesity. The meta-analysis found insufficient evidence supporting the claims that HCG is effective in altering fat-distribution, hunger reduction or in inducing a feeling of well-being. The authors stated “…the use of HCG should be regarded as an inappropriate therapy for weight reduction…” In the authors opinion, “Pharmacists and physicians should be alert on the use of HCG for Simeons therapy. The results of this meta-analysis support a firm standpoint against this improper indication. Restraints on physicians practicing this therapy can be based on our findings.”
