Lets get something straight. He did not avoid sugar. And no one should. Food falls into 3 main categories: Carbs, proteins, fats. Carbs fall into 2 categories, Sugars and Starches (which are just a chain of sugar molecules). Yes, it is possible to survive for awhile on just protein and fat, but NO ONE should be doing that. Sugar is necessary and good for you.
