Some foods that boost the metabolism include blueberries, almonds, whey protein, salmon, psyllium husk, spinach, turkey and oatmeal, as listed at the BodyBuilding website. Liquids, such as water and green tea, can also be used to boost the metabolism.
Boosting the metabolism helps the body to burn fats more quickly. Many of the foods listed also have other nutritional benefits.
Salmon is useful because it is low in saturated fat, while also being high in protein and the omega-3 fatty acid, according to the BodyBuilding website. Essential fatty acids can only be obtained from dietary sources, since they are not produced by the human body.
