Foods that speed up metabolism include spicy foods and protein-rich foods, according to WebMD. Other foods that speed up metabolism are whole grains, cruciferous vegetables and berries, states the Huffington Post.
The chemicals in spicy foods can boost metabolism, according to WebMD. Adding a tablespoon of chopped red or green chili pepper to recipes is a good way to get this effect. The benefits add up with regular use of spicy foods. Protein-rich foods help boost metabolism because the body burns more calories digesting protein than it does digesting carbohydrates or fat. Good sources of lean protein are white meat chicken, tofu, eggs and beans.
High-fiber foods speed up metabolism because the body takes longer to digest them, according to the Huffington Post. Whole grains, cruciferous vegetables and berries are all good sources of fiber. Whole grains include brown rice, quinoa, oats and barley. Cruciferous vegetables include broccoli, cauliflower and Brussels sprouts. Berries and other fruits with edible seeds or skin are especially high in fiber.
Two beverages that speed up metabolism are coffee and green tea. Drinking coffee in moderation gives metabolism a temporary boost due to the caffeine. Green tea not only contains caffeine but also has catechins, substances that speed metabolism for a couple of hours.
