I do too sometimes... I think the guilty feeling comes from eating just because something tastes good and not because you are hungry. Eating for non-hunger reasons is what got most of us fat in the first place, so it is only normal that eating food which tastes really good would make us feel bad. I only get that feeling when I know I am eating more than I need. It just so happens that when I am over eating it is probably because the food I am eating is really yummy .
