Eating certain types of foods improve your metabolism for short periods of time, but the best and most efficient way to improve it is to resistance train. Muscle tissue requires more energy per unit of mass than other tissues in the body. The more muscle mass, the higher your baseline metabolism.
That doesn't mean that you need to try to "bulk up" with lean muscle tissue to see a legitimate increase in metabolism. You just need to adopt (if you haven't already) a routine resistance training program that fits your goals.
