Year after year, studies report the pros and cons of caffeine consumption. The common theme, revealed by organizations such as The Centers for Disease Control and Prevention and the American Medical Association, is that a moderate intake of caffeine doesn't contribute to disease in an otherwise healthy person. It won't cause cancer. It won't cause high blood pressure. But it just might facilitate fat burning and spark your creativity.
Caffeine speeds up our metabolism.
It also breaks down fat, freeing fatty acids that can be burned during exercise. Studies have shown that conversion of fat to energy is about 30 percent more efficient when caffeine is consumed prior to exercise. The caffeine-enhanced fat burning can only occur while we're exercising. So don't expect to drop pounds simply by drinking an extra cup of joe each day. Higher glucose levels ward off hunger.
