Gary Smalley wrote a book called Food & Love, and in it he postulates that relationship issues can fuel food cravings ~ and food issues can create struggles in our relationships.
It certainly makes sense. Geneen Roth says much the same thing in her book, Women, Food & God. Solve your relationship with food and you'll clear up problems in other areas of your life.
The key here is to know which hunger needs to be fed ~ physical or emotional? Most people confuse emotional hunger for physical hunger, but despite their choices, the solution for emotional hunger isn't food.
We all crave connection ~ especially with our own hearts. Barring that, we end up looking for love in all the wrong places. Like in the refrigerator!
