Medical Research on the HCG Diet

June 18, 2013


 The research done by Dr. Simeons on the HCG Diet was published in 1954 in his book, 'Pounds and Inches', which is widely available at no cost on many websites. He designed his protocol to be very precise regarding the amount of HCG required for injection, for the number of calories and the types foods allowed, and for the optimal duration of the program. He also published a brief synopsis of his program in the British medical journal Lancet(vol. 2, pp. 946-947, 1954).

THE NATURAL HCG DIET & the medical community

The Natural HCG Diet & weight loss program has attracted lots of attention from chronic dieters as well as the medical community. The success of the HCG Diet  for weight loss has been remarkable in many cases and with it' increasing popularity there is also lots of negative press. We have had significantly positive results using the Natural HCG Diet with our patients.† Beyond weight loss, we have seen our patients have lower cholesterol, lower blood pressure, improved thyroid function, less arthritic pain and more energy post the HCG Diet. Before I go further, I want to note that the FDA does not approve HCG for weight loss.  In our private practice, HCG used along with the HCG Diet has been extremely safe and effective.

Medical Studies on the HCG Diet

More than 18,000 journal articles on HCG are found in the governments pubmed database.  Less than a few dozen of these having anything to do with weight loss. Most of the research on this hormone involves fertility, pregnancy, and the detection of cancerous tumors. What I want to do is call your attention to just three studies as examples of the confusion that is rampant in the medical literature on HCG and weight loss.

1963 Study on the HCG Diet

This study was published in the American Journal of Clinical Nutrition (vol. 12, pp. 230-234, 1963), at the height of popularity of the HCG diet plan in the U.S. In my reading of this article, it looks to me as though the researchers behind this study, from the University of California, San Francisco, School of Medicine, followed the Simeons protocol to the letter. There was one exception: the consumption of a baked potato each day, which is not on Simeons' list of allowed vegetables. The main result of the study was an average loss of 6.5 pounds in the HCG-treated group, compared with an average loss of 8.8 pounds in the untreated (control) group. The authors concluded that the hormone did not cause weight loss.  Many studies done on the HCG diet are done in a way that is not compliant with the intended HCG Diet created by Dr. Simeons and therefore, in our opinion is not a very good study. 

1973 Study on the HCG Diet

This study was published 10 years later, also in the American Journal of Clinical Nutrition (vol. 26, pp. 211-218, 1963). The researchers who conducted it, at the American Society of Bariatric Physicians Research Council, studied about twice as many subjects as the 1963 study above. The final result was an average loss of 19.96 pounds in the HCG group and 11.05 pounds in the control group. More importantly, the statistical analysis supported this difference as being significant. The conclusion of this study was that HCG did cause weight loss. Take Home Lesson on HCG DIET Studies Human subject research is the most difficult kind of study because of so many variables that are out of the control of the experimental design. Determining cause and effect is almost impossible. Nevertheless, we can see from some research that HCG can and does drive weight loss.In our own private & clinical practice we have seen the HCG Diet be extremely safe and effective.One More Thing about Leptins and HCG with the HCG Diet.  Early studies on lab animals are now beginning to show that HCG interacts with the hormone leptin. Leptin is the new master fat hormone that has been known only since 1994. Like HCG, leptin also carries a signal to the hypothalamus. It is our feeling that the more we find out about the interaction between these two hormones, the more we will understand how ingenious the Simeons protocol really is.
