Drink green tea

Green tea contains a plant compound called EGCG that has been shown to speed up the metabolism. “EGCG [may] block the action of an enzyme that breaks down noradrenaline, and noradrenaline stimulates many metabolic functions, including the release of energy from fat,” says Jonny Bowden, PhD, CNS, author of “The Most Effective Natural Cures on Earth.”

Daily Dose: 270 mg of EGCG
Depending on the brand, one to two cups a day should do it.
