The HCG treatment consists of a very low calorie diet in combination with HCG hormone treatments. During the treatment, you regularly take a small amount of HCG into your body daily. This HCG mobilizes body fat which circulates through your body providing energy and preventing hunger. This will make it possible to maintain the diet. HCG helps to burn the “mobile fat” – the fat that is stored around the hips, thighs, belly and upper arms.
