There are no such things as miracle treatments for a weight loss problem. Of course, it is possible to become slim through the use of fad diets, but you will not be healthy because crash diets deny you nutrients that are necessary for your body to function properly.
It weakens your health and what's more you are likely to go back to your former eating habits since the fad diet taught you nothing. You will be having the same problem again and again. Worse, according to studies people who have undergone repetitive weight loss diets, then became permanently overweight, and are in worse health than those who hadn't tried solving their weight problems at all.
