In the 1950s, researcher, A.T.W. Simeons, discovered that the hCG diet, a hormone that is naturally produced in pregnant women, combined with a very low calorie intake, would lead to fast weight loss. Although many Simeons followers did actually lose weight, Simeons did not consider that the human body cannot thrive on his dangerously low, 500-calorie per day, intake. Many patients suffered severe fatigue, while many others suffered more serious side effects. Diet Doc does not support the outdated hCG diet’s dangerously low calorie protocol and has benefited from decades of scientific research, combined with modern medical understanding, to develop their own, thoroughly updated version, encouraging patients to consume more than double the daily calories than that of the original hCG diet, without compromising health or fast weight loss results.
