My view is that it always comes down to moderation and self control. I don't buy into that sugar is the devil, or wheat is the devil (Water Boy reference), etc., but that the true devil is most folks inability to moderate their intake of sugar or grains or pasta or whatever (certainly is my 'devil').

If I were to redesign the food pyramid, I would make it a food circle, with a large inner circle of protein (and fat), and outer thin segments of all the other food groups.

I want to be able to enjoy some sugary things, and I won't feel bad about eating them, but I still have not been able to work out how to effectively balance my desire to stay fit thin and eat a variety of foods (hence for the last few years I yoyo 20+ lbs as I diverge from low carb).
