15 Foods That Burn Away Fat-Part 3

Green Tea and Coffee


Secret Ingredients: Caffeine and a chemical in the tea called EGCG


How they work: Caffeine helps speed up your heart rate. The faster your heart beats, the more calories you burn. EGCG works in a similar way, but instead of revving up your heart, it causes your brain and nervous system to run more quickly -- again helping you burn more calories.

In studies, researchers found that a combination of caffeine and a 90-mg dose of EGCG taken three times a day can help you burn an extra 80 calories a day. And that's just when your body's at rest.

A study conducted by the Canadian government found that soldiers who consumed caffeine in the 12 hours prior to a physical fitness test not only were able to work out longer before becoming exhausted, but also consumed more oxygen while working out. The body's oxygen requirements are directly related to the speed of -- guess what -- your metabolism, so the more oxygen you use, the more calories you burn during your workout!
