natural fat burner

It must have been nice if I would try the natural fat burner to lose the extra 12 pounds of my weight and 5 inches in my waistline. I have read that doing cardiovascular exercises early in the morning such as brisk walking, jogging or cycling could really help in burning extra calories. We have been fasting for the whole night and when we exercise early in the morning there are no foods to burn so we burn the extra fats instead.
