Me too, around 7-8 and then I lost it all at about 14-15.
I do remember one summer after vacation bible school and coming home starving and my mother feeding us Chef-boy-r-D canned spaghetti and meatballs a lot. She was also buying these Minnie sized frozen pizzas with hardly anything on it. I also remember a bag of Chips A'hoy cookies in the pantry. So, tons of carbs!!
