I've tried this. I'm one of those people that still feels hungry. For me, it has been all about calories. If I cut sugar/grains, that's fine and I feel better but I make up for it on the other side. I will eat too much fat and protein. So I have to strictly log my food to make sure I don't go over a certain amount of calories be it no sugar/no grain, paleo, lo carb, high carb. etc. I was I could eat intuitively but I think I'm too old to retrain!!
