Not that complicated.
Cut out all sugar, white flour, bread and pasta.
Bingo!
I'll continue to eat bread, sugar, unbleached white flour and pasta.
My genetic heritage can take carbohydrates. And keeps me lean even if I'm over 50.
Different strokes for different folks.
And genetics and exersize has a lot to do with how your body processes different types of food.
The better advice is to learn to listen to what your body needs.
There is no formula that fits everyone, regardless of what the food fetishists would like to believe.
