In all seriousness, my metabolism went away when I turned 23, so whenever I find a way to kickstart it again, I like to share it so that other people who have lost their metabolism can benefit too!

Think: Strong We all know weight-lifting builds   muscle, and the more muscle you have, the more calories you burn. What you may   not realize is that the calorie burn continues long after your last rep. In   a study at Southern Illinois University, exercisers who did a 15-minute resistance   routine burned 100 extra calories a day for three days afterward. Strength training   causes micro trauma to the muscles. Your body has to rebuild the muscle. It   does that by torching additional protein and carbs. Boost your fat burning:   Three days a week, do 1 to 3 sets each of five resistance exercises (think push-ups   and squats).

Lift First, Do Cardio Second Exercisers who pumped   iron 20 minutes before cycling melted more fat than those who didn't lift or   those who waited longer between lifting and doing cardio. So move right from   the hand weights to that bike or treadmill.

Spice Things Up That beyond-hot mustard that comes   with Asian takeout can rev your metabolism by 20 to 25 percent. It boosts production   of fat-burning hormones. Try adding one teaspoon to your usual vinaigrette.

Include Intervals Cyclists who pedaled at an all-out   effort with high resistance for a total of five 30-second sprints (that's just   2.5 minutes!) burned a whopping 200 calories, according to recent Colorado State   University research. Don't forget to recover between intervals: Here participants   recouped with four minutes of slow pedaling with low resistance after each burst.   Changing the intensity forces your muscles to work harder.

Guzzle H20 It will keep your metab humming when   you're just bumming around. In a University of Utah study, participants who   downed eight to 12 glasses of water a day burned more calories at rest than   those who drank four. Water not your cup of tea? Freeze bits of peeled citrus   fruit and use them in place of ice cubes.
