He He He, love the mental picture of your son hugging a loaf of bread. Sounds like my two boys, the idea of no carbs terrifies them, but they have both made some changes and can already see the results. My eldest suffers with terrible hay fewer, but when he eats less carbs its much better. I just give them as many primal meals as possible and I make a point of not saying that it is. It quickly becomes "normal". They still have potatoes and rice, but definitely no pasta etc.
The greatest of faults, I should say, is to be conscious of none.
