Some health experts and nutritionists are advising against the diet, however. They say the diet lacks proper nutrition for adults because it will not give you a sufficient amount of protein, fiber, vitamins and minerals.
If I could add a small editorial note here to anyone considering such a diet, keep in mind a diet is just part of the battle, you have to exercise. To make that point, it's good to remember that Lady Gaga is constantly performing on stage for hours in addition to regular training.
