While I'm not in favor of all these people who love sugar bashing in order to prove they can pay attention to mainstream media and act like they know something, I find I do better on more starch and less sugar. Wheat, meat, and cheese are probably my staples now that I've given up "dieting". Eating intuitively doesn't have me chasing much sugar. Too much sugar causes me insomnia and it doesn't seem to take heaping loads of it to constitute an excessive amount for me as I once thought. I wish I knew that during my ~1.5 years of strict Peat.
Moral of the story - don't preach anyone's advice, regardless of how much evidence they have, until you have been able to log your own experiences with it.
