The Cabbage Soup Diet will affect every person differently. Certain body types are able to handle the low-carb, low-protein, and low-cal diet better than other body types. If you let yourself get hungry then this diet will turn out to be extremely hard. You can try adding small portions of protein such as egg whites, chicken breast, and dried nuts to help with the symptoms. Or take an Excedrin or other headache reliever with caffeine.
