Body composition (the more muscle we have, the higher our metabolisms), protein intake, hormones, stimulant use (like caffeine, which speeds up metabolism temporarily), fasting (which lowers metabolism) and environmental temperatures (i.e. when it’s hot or cold out, our body burns more calories trying to keep itself at a constant temperature) are also considered to have an impact on metabolism, registered dietitian Tristica Curley of Fueling with Food adds.

You've heard this one before, but it's worth repeating! Eating smaller meals more often throughout the day can help fire up your fat-burning furnace. Susie Akers, director at the Aamoth Family Pediatric Wellness Center at MetroHealth and gastroenterology dietitian, recommends you consume at least three to four times a day instead of only one to two times to keep your metabolism up and avoid excessive portions with large meals.


When you’re looking to give your body a boost, you know turning to a solid weightlifting session, afternoon bike ride, even a a quick 30-minute HIIT session will get your metabolism cranked up. Metabolism is simple. It’s a series of chemical processes by which your cells produce the energy needed to sustain life—and the higher it revs, the more energy your body burns.
Experts agree that including a weekly cheat meal into your healthy-eating plan can actually help you reach your weight loss goals. Having a strategy is key: “By planning your cheat meal, you know what you’ll be eating and can cut a few extra calories earlier in the day,” says Jim White, RD, ACSM Health Fitness Specialist and owner of Jim White Fitness & Nutrition Studios. “This also allows you to really pick a favorite food instead of wasting calories on something you didn’t enjoy.” Amy Shapiro, MS, RD, CDN, Real Nutrition NYC, gives similar advice. “Pick your poison. If you’re going out, pick your splurge. Are you going to dig into carbs like a bread basket or pasta or dessert? Or are you planning on tossing back a few cocktails?” She urges cheaters to avoid consuming all three of those common categories in one sitting. “Focus only on one,” she says, adding that by saving the others for another time you can “enjoy without going overboard.”
Think of every bean as a little weight-loss pill. One study found that people who ate a ¾ cup of beans daily weighed 6.6 pounds less than those who didn’t—despite bean eaters consuming, on average, 199 calories more per day. The magic is in the perfect combination of protein and fiber: Studies show that those who eat the most fiber gain the least weight over time and that eating fiber can rev your fat burn by as much as 30 percent. Aim for about 25 grams of fiber a day—the amount present in about three servings each of fruits and vegetables.
Noshing throughout the day is a proven strategy to help you curb hunger and eat fewer calories overall. Now, experts are promoting nibbling versus gorging as a way to keep metabolism running by holding blood sugar levels steady and preventing weight-gain-promoting insulin spikes. Enjoying six small meals a day should do the trick; keep them around 300 calories each, or divide your usual day's calories by six.

What should you be having? Morning munchies that are slow to digest and leave you feeling fuller longer. Try a mix of lean protein with complex carbohydrates and healthy fats, like this power breakfast, recommended by Berardi: an omelet made from one egg and two egg whites and a half cup of mixed peppers and onions, plus a half cup of cooked steel-cut oats mixed with a quarter cup of frozen berries and a teaspoon of omega-3-loaded fish oil.
Some ingredients in energy drinks can give your metabolism a boost. They're full of caffeine, which increases the amount of energy your body uses. They sometimes have taurine, an amino acid. Taurine can speed up your metabolism and may help burn fat. But using these drinks can cause problems like high blood pressure, anxiety, and sleep issues for some people. The American Academy of Pediatrics doesn’t recommend them for kids and teens.

Sprinkle a few hot peppers into your lunchtime soup or evening stir-fry. They temporarily boost your resting metabolic rate, according to research done at Laval University in Canada. Here's why: Capsaicin, a compound found in jalapeño and cayenne peppers, temporarily stimulates your body to release more stress hormones, such as adrenaline, speeding up your metabolism and thus increasing your ability to burn calories, says study coauthor Angelo Tremblay, director of the Institute of Nutraceuticals and Functional Foods at Laval. Bonus: The pepper-eaters had less of an appetite, Tremblay found, probably because the spiciness of the food made them feel full.


While nutritionists agree that there is no magic food to revving up your metabolism, getting enough exercise, especially the right kind of exercise, is key. Experts suggest strength training two or three times to build lean muscle mass. “A pound of muscle burns up to nine times more calories than a pound of fat,” says nutritionist Lisa Stollman. “Lifting weights is a great way to build muscle mass.” However, the point is not just to build lean muscle mass, but to maintain it. “As we age, we start to lose muscle,” says Pincus. “Strength training not only builds muscle groups to burn more calories, but also helps preserve them and prevent loss.” Check out these other nutritionist-approved ways to speed up your metabolism.
Playing up your favorite body parts can boost your confidence and draw attention away from spots you want to minimize. Sculpting your shoulders, arms, chest, and back, for example, can help balance heavier hips so you look more proportionate. Plus, you'll be firmer all over. Celebrities do it all the time: These seven sets of sexy, toned legs are proof!
The theory makes sense: Your body burns carbs for energy, but if you eat them before you go to sleep, your body just stores them as fat. One study in the European Journal of Nutrition put two groups of men on identical weight loss diets. The only difference? Half of the group ate their carbs throughout the day while the second group reserved carbohydrates for nighttime. The result? The nighttime carb group showed a significantly higher diet-induced thermogenesis (meaning they burned more calories digesting their food the next day). Moreover, the daytime-carb group showed increased blood sugar levels.
Before you throw a French press at someone's head, read on. You don't have to eliminate coffee — but throw a few cups of green tea into the rotation and you may find that your pants fit a little looser. "Research shows that the caffeine and catechin in green tea has the ability to increase your metabolic function by 4-5 percent and improve fat oxidation by 10-16 percent," explains Bonfiglio Cunningham. Green tea comes with an extra perk, too — its antioxidant properties. "The antioxidants found in many teas fight free radicals in the body, improving the aging process and lowering the risk of disease."
But there are easy things you can do to stoke your fat-burning potential. "There's no reason you can't have the same metabolism in your 30s and 40s that you had in your 20s," stresses Pamela Peeke, M.D., author of Fight Fat After Forty. Here are some experts' tips on how to boost your metabolism — so you, too, can guiltlessly binge on Ben & Jerry's every now and then.
