There's a familiar cycle in our culture: People over-indulge, gain a lot of weight, then starve themselves or devote themselves to punitive diets that don't allow a normal range of foods. There is a better way - which sounds too simple to be true. Just eat less - of everything.
When you're having a meal and picking what that one item, or one plate of food will be...
1) Pick what your mind wants: logical and healthy food, perhaps a vegetable + protein + carbohydrate combination item such as a sandwich, soup or salad.
2) Pick what your heart craves: something really delicious and satisfying.
3) Pick what your soul needs: food that is a symbol of your self-love and care.
