The last time I lost a significant amount of weight it was simply by eating when I was truly hungry and stopping when I was satisfied..and then not eating again until I was truly hungry. At times I would get that my body only needed a smaller portion to be satisfied and lose weight, while other thin people could eat as much as they wanted without giving thought to the scales. I had to learn to be content with my body and it's needs and not give in to its wants. It was the only other time I felt in control of my eating; and I did fine until I just got lazy and well lost track of things.
Now I'm relearning that I can enjoy company, parties, etc. etc. without having to indulge in great amounts of food. It's not always easy, in fact it can be pretty hard right now, but the small steps are paying off and there is a great feeling inside when I know I'm not dependent on food to make get togethers fun and enjoyable.
Have a wonderful weekend!
