If you want to lose weight then diet and exercise is the only answer. Note, if you lose it fast you will gain more back. So, go slow. You can cut down on your carbohydrates and fats. Drink lots and lots of water and eat plenty of fruits and vegetables so that you can get rid of the toxic in your body easily. While you are working out put on tights and long pants so that you would sweat those fats out.
The Dolly Parton soup works quick and it shows on your scale. It is a vegetable soup of cabbage, celery, bell peppers, and onions. Eat a bowl of this along with your regular meal at noon and dinner to get desired results.
