There is no doubt that the HCG hormone diet works. It requires the dieter to restrict his or her calorie intake to a very low amount for a number of days or even weeks. Any dieter successfully restricting calorie intake for such a period will almost certainly lose significant weight. Many doctors are still unconvinced that the HCG hormone plays a large role in the weight loss. However, there is anecdotal evidence that hundreds of dieters following the protocol have safely shed huge amounts of fat in a much shorter period of time than any other diet.
It goes without saying that as with any other low calorie diet, the dieter should always consult with their doctor before commencing, and should be careful to consume each day an adequate amount of minerals and vitamins.
