If you have ever "lost" weight, say 20-30 pounds, you gained it back. WHY? Because you didn't feel emotionally comfortable at that lower weight. You loved weighing less but emotionally you had to get back to your prior weight. That's the same reason you don't weight 20-30 pounds more than you do. You wouldn't feel comfortable at that weight. That's why "losing weight" is a suckers game. It's only a temporary thing.
