What do experts think of the diet? Although simple and doable for most people, most experts don’t like the diet because it is low in vegetables, fruits, fiber, and protein. These are necessary for a balanced diet. It also does not mention exercise as necessary to maintain health. Sustainable change is required for successful weight loss, and this diet does not really provide that. You can follow it for a few weeks and try to use it to jump-start your weight loss, but exercise must be included. It may be too simple of a diet, and you need to make other good changes that will last a lifetime. But, the diet is a good starting point.
