Eat more fat-burning foods
Certain foods have a thermogenic effect, which means you literally burn calories as you chew. Others have nutrients and compounds that crank up your metabolism. Stoke your metabolic fire by eating more of these foods, while cutting out unhealthy snacks and empty calories.
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.
Protein has a high thermogenic effect: You burn about 30% of the calories the food contains during digestion (so a 300-calorie chicken breast requires about 90 calories to break it down).
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 metabolism slows because the body’s not getting what it needs to work efficiently.
Capsaicin, the compound that gives chili peppers their kick, heats up your body, which makes you melt additional calories. You can get it by eating raw, cooked, dried, or powdered peppers“ Add as much cayenne or hot sauce as possible to soups, eggs, and meats.
