While you’re planning your meals, you may want to add kiwi fruit to your diet.  Kiwis pack a lot of vitamin C, but if you add 500 mg of it to your day, you burn up to 39% more fat when you’re exercising.  Don’t get too much C, though, because once you get to the 2,000 mg mark, you start experiencing adverse effects like bloating, gas, and diarrhea.

Another metabolism boosting measure is to watch what you drink.  Adding ice to a drink makes your body work harder because it has to heat it up in your stomach, which increases your metabolism.  Also, ingesting a caffeine drink like coffee or tea can raise your heart rate and increase your metabolism.
