I agree. We have evolved to run on two sources of fuel but fats are a far more efficient fuel. I viewed a lecture recently by Fettke who explained this really well by saying before the advent of modern food availability (by modern I mean before the advent of farming 10, 000 years ago) humans ate carbs in the summer and autumn to lay down fat for the leaner times of winter. We now live in a time of perpetual summer.
