Yeah. There is a balance between being a normal kid and going for 100% TIR everyday. No carb would help, but what would the trade off be. We let him have cake (without icing) and let him have banana and all sorts of carby food.
I understand adults that want that extra control for themselves, but I think it is another thing to make someone else do it. Like training for a marathon might be cool if you do it for yourself, but would be torture if someone else was making you do it.
