How much weight loss diet can I lose? Everyone is different, and everyone will lose at a different rate. There are many factors that will determine how fast one loses. A weight loss diet needs, age, exercise, medical conditions, family history and water intake can all have a direct effect on your success. For instance, one who has more to lose will usually drop quicker than someone who has just a few pounds to lose will (assuming they do everything else the same with our weight loss diet). Our guarantee does not state specific lose amounts, we simply guarantee that you will be satisfied with our products.
