Without adequate exercise, you cannot maintain a high enough metabolic rate to burn your food efficiently. A pill can't do that for you; foods alone can't do that for you. Exercise is the only way to achieve it.

Make exercise a regular part of your life. And don't get hung up if you can't do it at the same time every day. If you miss your routine in the morning, don't wait until the next day and try to do twice as much. Instead, try to fit in some exercise -- even if it's just a little bit -- every day.  Even a marathon begins with a single step.
