Is there any way to speed up your metabolism?

Exercise: The simplest way is to increase your exercise.

Build muscle.: Since muscle cells have a higher metabolic rate (i.e., they need more energy or calories) than other tissue, my answer would be to build more muscle. You can do this through strength training with free weights, nautilus-type equipment in a gym, stretch bands, or a variety of other ways. When you get to be around 35, you lose muscle mass naturally - unless you build and defend it!

Speed metabolism.: Weight training builds lean muscle which is metabolically active around the clock, day and night. While some studies suggest that cardiovascular exercise may stimulate the metabolism for as much as 48 hours after the exercise, it may be much less time. Both are best in combination. As well, eating a small healthy meal of lean protein and complex carbs every 2-3 hours speeds the metabolism.
