I don't understand why people diet without exercise. The two go hand and hand. Don't have time? Make time. It's really a small commitment with an enormous upside. It's like trying to become a billionaire without investing any of your money. You need to invest your healthy diet into a good exercise program and the rewards will be substantial. Then you can do carb loading (eating carbs on days you exercise and avoiding carbs when you are not exercising) and avoid all those no-carb side effects.
