It’s true: Certain foods have a very high thermogenic effect, so you literally scorch calories as you chew. Other eats contain nutrients and compounds that stoke your metabolic fire. Feed your metabolism with these.

Whole grains
Your body burns twice as many calories breaking down whole foods (especially those rich in fiber such as oatmeal and brown rice) than processed foods.
Green tea
Drinking four cups of green tea a day helped people shed more than six pounds in eight weeks, the American Journal of Clinical Nutrition reports. Credit EGCG, a compound in the brew that temporarily speeds metabolism after sipping it. To up your intake, keep a jug of iced tea in the fridge.
Lentils
One cup packs 35% of your daily iron needs—good news, since up to 20% of us are iron- deficient. When you lack a nutrient, your metab slows because the body’s not getting what it needs to work efficiently, says Tammy Lakatos Shames, RD, co-author of The Secret to Skinny.
