just like a hard drug, our bodies can crave carbs and sugars. If you find a food that is like that for you, you must resist! otherwise, it keeps triggering the desire for more. for me, chocolate is one such food. it is also a highly intelligent food--can learn my name in the supermarket aisle, can jump into the cart, then continue to call me at home until I eat it. I've learned to cover my cart in that aisle! I refuse to bring any home.
