Penni, my husband has the same problem He grew up real poor, and always worried when his next meal would come. He always ate fast, and rushed to get seconds as if there weren't going to be any. (Rarely was there enough for seconds).
I have the problem of not being able to leave a plate with something on it. Of course that comes from scoldings as a child.
The second problem I have, is always thinking I can have a dessert if I eat my food.
My husband says I eat like a kid. Never learning how to eat grown up foods (vegetables, fruits etc.) I eat/ate foods high in sugar and preservatives. I never realized that until recently.
Usually I eat when I am extremely stressed. Even when I am not hungry
