I think that eating a moderate amount of carbs, such as would be found in a diet of varied whole (unprocessed) vegetables and fruits, is the best course of action. I think if you choose some "special" diet emphasizing a low or high proportion of carbs, protein, or fats, you are asking for trouble. And no, a diet of varied fruits and vegetables is not low in protein. Low in terms of the standard American diet, but not low in terms of what we need.
