Caffeine shown to boost fat loss with exercise
Researchers found people who had caffeine before their exercise routine burned 15 percent more calories for three hours after their workout. The effect kicked in for a 150 pound woman after a 12-ounce cup of coffee.
But before you brew a whole pot, keep in mind there's a risk of overdoing it. Dietitians say the maximum amount of caffeine you should have for enhanced performance is around 16 ounces of coffee. That's about the amount you could pour into an average travel mug.
