Instead of concentrating on why you don't change your eating so you can lose the weight, here's an alternative: Concentrate on why you might want to stay with your eating behavior as it is now.
Maybe you think that to lose the weight would mean feeling small and vulnerable. Maybe you feel somewhere that food is your best friend, and who wants to lose a best friend. Maybe you feel that any effort on your part to lose weight will be futile anyway. Maybe going ahead to change your eating habits and your weight means giving up too much that is important to you.
These are essential questions to ask. The underlying idea is: What does my way of eating do for me?
This is another way of approaching a weight problem - coming at it from a different angle. If you can consider this idea, it might just be the eye-opener you've been looking for.
