The basic summary of the diet is this. Homeopathic HCG drops trigger the body to mobilize excess fat reserves into energy. When combined with a low 500 calorie diet, excess fat melts away as the body burns must rely on fat reserves for energy due to the low calorie intake. While the idea of a 500 calorie diet may seem impossible to some dieters, homeopathic HCG actually helps to suppress appetite. The diet also allows for a large variety in food selection within the guidelines that meat be limited to lean meats such as chicken, turkey and fish and to avoid foods with high starch and sugar content.
As with any diet, the end goal of this diet is to maintain a fit and healthy lifestyle long term. Once ideal weight is achieved, dieters simply increase calorie intake sticking to the same basic principles of the diet; portion control, low fat, low starch and sugar. Moderate exercise is of course beneficial but not required to maintain ideal weight.
There are numerous publications on this subject including Kevin Trudeau's book "The Weight Loss Cure". Trudeau provides a great in depth understanding of the HCG drops diet but does not go into to detail about sources for purchasing HCG products.
