Proponents claim dramatic results: losses of 10 to 20 pounds in less than two weeks. And physiologically, this makes sense. By severely restricting carbohydrates, the body burns through its glycogen stores, shedding the water bound to those molecules. This creates a rapid, exhilarating drop on the scale.
