The world renown hCG diet, used in the treatment of obesity, was founded by Dr. AlbertT. W. Simeons who is now and then referred to as Dr. A. T. W Simeons.

He was born in England, and he spends his childhood in London. After that he studied Medicine in the University of Heidelberg. Soon after that, Dr. Simeons moved to Germany and then in Switzerland. While he was there, he worked many different areas of Medicine, when he decided to specialise in Tropical medicine. His decision leads him to Hamburg where he started visiting the School of Tropical Medicine.

While he was there, he was working on injection remedies for malaria and different methods of staining malarial parasites. For his contribution in that field, Red Cross Order of Merit by the Queen of England in 1931.

In 1931, he moved and resided in india for 18 years, where he continued to practice medicine and where something remarkable came to his attention. While in India, he discovered that though many women seemed to be undernourished, they still gave birth to healthy babies. He also observed that their bodies still produced large amounts of human Chorionic Gonadotropin ( hCG) which was breaking down bodily fats and resupplying them to the babies resulting in healthy babies. He moved from India and settled in Rome, Italy in 1949.

There he published 'Pounds and Inches: A New Approach to Obesity' in 1954. His theory about fat breakdown riches different periods of starvation, but after around 3 months the fats that are in the body break down and nutrients and energy. He also discovered that the secondary fat could be the reason for weight gain since they are not naturally raised in the body. He did a great research on that during the years and when his writing was published the people were really interested in his theory. But what is most important, the practice brought him to great results.

Continuing on with his research, in his report he published, Dr. Simeons was surprised to notice that when subjects were given a low calorie diet combined with hCG, it resulted in a more holistic weight loss that in essence 'reshaped' the body. This was also noticed in subjects who did not exercise. Even more interestingly, patients did not experience any untoward symptoms such as headaches, weakness, and irritability or hunger pangs. He ultimately concluded from his research that it was the secondary fat reserves that were broken down that helped the subjects slim down dramatically.

Organizing his findings together in a record, he created a famous weight-loss program which has gripped the market today. The program has been used by thousands, and the results have been positive. What started as an observation project led to the most effective weight-loss and maintenance program of the twenty-first century.
