It's just a gimmick that dumbs down some general principals on carbs and overall nutrition. In fact I think it can be harmful over a long stretch of time. I wouldn't waste my time or effort trying to follow this or any "diet"
Design your own nutritional routine (heh heh, diet), take Atkins suggestions into consideration if you wish; because opinions never hurt, but I would not follow this diet strictly under any circumstances
My 2 cents..
