I can't say I agree with you that everyone needs to eat starches for energy once they reach their desired weight. it definitely seems to be an individual thing, but a lot of us feel like crap if we eat starches, including primal ones. If I eat starches I have no energy at all, I feel utterly fantastic and bursting with energy on a very low carb diet completely free of starch.
