Ideally, we sleep about eight hours for every 24. Most people spend another seven to ten hours sitting at their desk. That means most of us spend the overwhelming majority of our time sedentary. Our bodies weren’t designed for this level of inactivity—most of humans’ evolutionary history involved being active, searching for food and fuel. Nutritionist Lisa Jubilee says that one way to burn more calories daily is to stand more and sit less. She cites a British study which found that standing at work burned 50 more calories per hour than sitting. If that doesn’t sound like a lot, consider this: If you stand for just three hours of your day, in one year you’d expend more than 30,000 extra calories—which amounts to about 8 pounds of fat!

Refined carbs, such as bagels, white bread, and potatoes, create a surge in insulin that in turn promotes storage of fat and may drive down your metabolic rate, says Louis Aronne, M.D., an obesity specialist at New York Presbyterian Weill Cornell Medical Center, who recommends high-fiber carbs instead. "It's important to keep carbohydrates in your overall diet, but focus on vegetables, fruits, and whole grains, which have less of an impact on insulin levels," he explains.

Stress can actually cause the body to metabolize food more slowly, according to research published in the journal Biological Psychiatry. To make matters worse, the food we crave when we’re stressed out tends to be fatty and full of sugar. Researchers say that the combination of high-cal cravings and a stress-induced, snail-paced metabolic rate can result in significant weight gain. To keep your metabolism running strong, fight stress with laughter. Research shows that smiling and laughing causes levels of stress hormones to diminish.
Cardio is still important, too. "Respiratory function is another big part of metabolism, and to increase that you need to be regularly getting your heart rate up," says Sasso. She recommends extended periods of walking, jogging, or some other form of moderate to intense aerobic activity, as well as body-weight circuit training with no rest between sets. Gibbons points out that cardio workouts generally burn more calories during exercise than strength-training—also important if your overall goal is weight loss or weight maintenance.

Whole foods contain an assortment of vitamins, minerals, and nutrients that act as metabolic spark plugs, giving you the energy to get up and move around. That’s the theory behind increasingly popular diets like Paleo, which eschews processed foods in favor of lean meat and vegetables. Without preservatives and unnecessary crap in your food, your body will burn clean, and that translates to a faster-moving metabolic engine.


Clocking in at caffeine counts higher than a cup of coffee, kola nut teas are sure to zap any morning drowsiness—and set your metabolism up for a hotter burn. In a study published in the journal Food Science and Biotechnology, researchers found that caffeine revs the sympathetic nervous system and increases lipolysis. Look for teas made from this caffeine-containing fruit; if you want to skip the label reading, just grab a box of Celestial Seasonings Fast Lane, which clocks in at 110 milligrams of caffeine.

Caffeine may provide a bit of a boost to the metabolism, especially when ingested before exercise, but no amount of metabolic boost can burn off the empty calories that energy drinks supply. According to one study published in Mayo Clinic Proceedings, a typical energy drink serves up a quarter cup of sugar—calories that hit your body all at once and trigger fat storage. If you want to burn calories, try the miracle beverage known as tap water. According to a study published in The Journal of Clinical Endocrinology and Metabolism, after drinking two tall glasses of water (17 ounces), participants’ metabolic rates increased by 30 percent.
In a small German study, subjects who drank 16 ounces of water at a time experienced a 30 percent increase in metabolic rate during the following hour, burning an extra 24 calories. The researchers recommend cool water because the body expends extra calories warming it up to your body temperature. Water's not the only healthy drink. We sipped our way through dozens of smoothies, teas, and juices to find this list of the most delicious and nutritious liquids.
Tea, often used in many diet fads is scientifically proven to boost your metabolism while trimming your waist line. In a study published in the Journal of Medicine Investigation, researchers tested the effects of oolong tea on energy metabolism in 11 healthy Japanese females who either consumed water, oolong tea, or green tea. In comparison to water and green tea, oolong tea increased energy metabolism by 10 percent which increases the overall metabolic rate. The polyphenols — compounds found in tea — are said to be responsible for the enhancement of the females' metabolism.
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.”
A 2003 study in the International Journal of Obesity demonstrated that a low-calorie diet that’s rich in almonds could help people shed weight. Not only do the good monounsaturated fats in almonds have an effect on insulin levels, say scientists, but also give dieters a feeling of fullness, meaning that they are less likely to overeat. So stock your pantry with almonds, walnuts, and nut butter.
It’s important to remember that you are unique: Everyone was born with a different biochemical make-up. You have trillions of little energy factories called mitochondria that provide the fuel to run everything in your body. If you can remember high school biochemistry class, you know mitochondria convert the oxygen you breathe and the food you eat into energy for your body to use.
Weight loss doesn’t get easier than this: Simply drinking more water may increase the rate at which healthy people burn calories, according to a study in The Journal of Clinical Endocrinology and Metabolism. After drinking approximately 17 ounces of water (about 2 tall glasses), participants’ metabolic rates increased by 30 percent. The researchers estimate that increasing water intake by 1.5 liters a day (about 6 cups) would burn an extra 17,400 calories over the course of the year—a weight loss of approximately five pounds!
Some things, though, aren’t that simple. For instance, someone with a higher metabolism burns more calories at rest than someone with a lower metabolism, and can therefore get away with eating more food—even junk food. But a high metabolism isn’t a privilege reserved for a select few lucky enough to be born with it. You can raise yours and reap the benefits, too.
This tea is known for its powerful thermogenic effects—meaning it turns up your body’s calorie-burning mechanism—and can also promote weight loss by improving insulin sensitivity. In a Nutrition and Metabolism study, participants were divided into two groups where one group took a placebo 60 minutes prior to exercise and the other group ingested a 1,000-milligram capsule of yerba maté. Researchers found that those who consumed the herb increased the beneficial effects their workout had on their metabolism. Yerba maté is just one of the best teas for weight loss!
If you always opt for coffee over tea, you could be missing out on a major metabolism boost. A Penn State animal study found supplementing exercise with green tea can actually boost weight loss. In fact, after 16 weeks, rats experienced a body mass reduction of 27.1 percent and an average abdominal fat mass reduction of 36.6 percent. What’s its magic? The brew contains catechins, a type of antioxidant that triggers the release of fat from fat cells and helps speed the liver’s capacity for turning fat into energy.
