For the best chance at losing your unwanted weight, you don’t just try to change your problem eating behavior, which is eating too much food or eating too many fattening foods. You must do all you can to change your problematic love relationship with food.
Changing your attachment to food involves very personal kinds of change. You might, for instance, need to change the way you soothe and comfort yourself. Where it used to be soothing and comforting through food, you will now have to think of other non-food possibilities for soothing and comforting. You can no longer rely on calorie-rich nighttime snacks to sop up your anxieties from the day and make you feel all better. Somehow, some way you will have to find it in yourself to deal with your anxieties sans these weight-gaining snacks.
Changing a problematic love relationship with food is what makes losing weight possible and permanent.
