#1.)  EAT MORE OFTEN.  Your metabolism is like a furnace:  If you go too long without feeding it, it dies out and can be hard to get going again.  You should still eat the same amount of food . . . just break it up into six meals instead of three.

#2.)  SNACK ON PROTEIN.  Eating things like meat, cottage cheese, and eggs, either with each meal or in between meals, can maximize the amount of calories you burn.  A study found that your metabolism can DOUBLE after eating a high-protein meal with fewer carbs.

#3.)  STRENGTH-TRAIN.  When there's more muscle on your body, you use up more calories . . . even when you're just sitting around.  By working out a few times a week, you can increase your metabolism by almost TEN PERCENT in just a few months.

#4.)  REV UP YOUR CARDIO.  The harder you exercise, the higher your metabolism goes.  So try adding in a few intense spots to your workout.  For example, if you jog, try sprinting for one or two minutes a few times during your run.

 --A study found that adding intense intervals to your workout can help you burn up to 36 PERCENT more body fat.

 #5.)  DRINK SOME COFFEE.  Drinking a caffeinated beverage like coffee, tea, or even soda can temporarily increase your metabolism by 3 or 4 percent.  But don't go overboard.  One cup can burn 10 extra calories an hour, but too much will make you jittery.  (Glamour.com)
