Hello, i would not recommend taking these diet pills. They are not good for you. First of all, many of the commercial stuff you see on television is untested or unproven , so you take them at your own risk. Second of all, those pills do actually block your fat cells but by doing so they also block the vitamins and minerals in your body and in that way you are harming your overall health. Third of all, you will build tolerance against them in couple of months which means that in a month or two they will have no effect on your weight whatsoever so its the waste of money and health if you use them. There's nothing healthier than a daily exercise.
