If you can afford to take them all you will reduce hunger and lose weight at a much faster rate. Low metabolism and chronic hunger are why you gained weight. Taking the right supplements makes a difference.
This diet works because it's designed to reduce chronic hunger and turn up your metabolism so high that you burn massive amounts of calories. Metabolism is the combined activity of 37 trillions cells that make up your body. That activity is dependent on the availability of nutrients but you can't get enough, even if you eat perfectly. To make up the difference you need to supplement with food-based supplements or supplements made from real food. That way you combine get a variety of 25,000 nutrients your cells need to function and burn more calories.
If you eat nutrient rich food and supplement with the right combination of food based supplements, you will turn up metabolism to the point where you will not only improve your health, you will lose weight faster and easier than you ever thought possible.
