A 1999 study in the American Journal of Clinical Nutrition found that people who consumed green tea burned more calories than those who took either caffeine alone or a placebo. For weight-loss benefits, pour 2 cups of water, brought just to a boil, over 1 teaspoon of green tea leaves. Steep in a covered container for 30 minutes. Drink up to 3 cups a day.
