The likely reason why HCG helps both men and women lose weight differently and better than with just a low-calorie diet alone is because the loss comes from fat body (fat) mass and not lean body (muscle) mass.

modern clinical trials

With more modern clinical trials such as those recently performed by Sheri Emma M.D. to again demonstrate how HCG may be working for lasting weight loss, the protocol is widely recognized due to its level of safety and effectiveness.

First outlined in the now infamous "Pounds and Inches" book published by the British endocrinologist Dr. Albert T.W. Simeons of the Savalator Mundi International Hospital in Rome, the weight loss protocol references a combination of a low calorie, low carbohydrate and fat, and high protein diet along with low-dose pharmaceutical grade HCG injections. 

Dr. Simeon first studied pregnant women in India who were on a calorie-deficient diet, together with “fat boys” with Froelich’s Syndrome.  The well documented manuscript explained in great detail the basic causes and treatment of obesity and how patients who have once taken the HCG treatment never seem to hesitate to come back for another short course as soon as they notice that their weight is ever again getting out of hand. 

The HCGPDX Program has been developed to incorporate years of extensive HCG research with four decades of patient care in naturopathic medicine, which emphasizes prevention, treatment, and optimal health.
