Spreading your meals throughout the day might keep you from getting too hungry and overeating. If so, it is a good idea. Athletes perform better when they eat more often in smaller amounts. If you are someone who has a hard time stopping once you start eating, 3 meals a day may make it easier for you to stick to an appropriate intake than lots of little snacks. 

Add mustard to your meal, and feel the burn—literally! Scientists at England’s Oxford Polytechnic Institute found that by eating just one teaspoon of mustard (about 5 calories) can boost the metabolism by up to 25 percent for several hours after eating. The benefits, researchers say, may be attributed to capsaicin and allyl isothiocyanates, phytochemicals that give the mustard its characteristic flavor.
It’s not just about being a gym rat. A study in the American Journal of Clinical Nutrition found that non-exercise related activity, such as tapping your foot or fidgeting at your desk, can help keep off fat. To integrate more movement into your everyday routine, Pincus suggests opting for a standing or transitional desk, or just making sure you don’t spend the entire workday sedentary. “Set a timer to walk around your office every half an hour, do a few squats, something to keep the body moving,” she says.
Metabolism is known scientifically as all of the chemical reactions that occur within the body, but the term sometimes is used to refer to the essential process of converting ingested food into energy. Metabolism is the process behind responsible all your movements, your thought process, and how you grow. The constant process is inextricably linked with life; once metabolism stops, so will the living organism, says Discovery Health. A two-part process, metabolism is influenced by the way you eat. Anabolism, one part of metabolism, is the process in which energy is created and stored; smaller molecules come together to create bigger molecules, eventually building up to organs and tissues. Catabolism, the second process of metabolism, provides the energy required for cellular activity by breaking down carbohydrates and fats to release the energy, says Kidshealth.org.
It's one of the most frustrating realities of dieting—if you cut out too many calories, your metabolism thinks times are lean and puts the breaks on fat-burning to conserve energy, Hunter explains. Here’s the trick to keeping your metabolism revved up while dieting: Eat enough calories to at least match your resting metabolic rate (what you'd burn if you stayed in bed all day; calculate yours here). That's about 1,330 calories for a 5-feet-4-inch, 150-pound, 40-year-old woman.
Want to have a faster metabolism? Install apps like f.lux or Twilight on your devices. They reduce certain parts of the light spectrum as your bedtime approaches. Studies have shown that LED lights in phones disturb the production of the sleep hormone melanin. A purring metabolism is greatly helped by a good night’s sleep. So take your late-night texting down a notch or two… At least in terms of screen brightness.
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.

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.
Load up on low-fat dairy: Women who consumed milk, yogurt, and cheese three to four times a day lost 70 percent more body fat than women who didn't eat dairy in a study published in the January 2003 American Society for Nutritional Sciences Journal of Nutrition. The reason: Calcium, along with other substances in dairy, actually revs up your metabolism, telling your body to burn excess fat faster, according to study author Michael Zemel, Ph.D., director of the Nutrition Institute at the University of Tennessee in Knoxville. And no, fortified o.j. won't do the trick. The best results come from dairy products instead of from other calcium-rich foods (like broccoli), calcium-fortified products (such as orange juice) or supplements. Women reap the largest fat-burning benefit when they consume three servings of dairy and 1,200 milligrams of calcium a day, Zemel's research shows.
According to a study in the Journal of Applied Physiology, strength training increases your resting metabolic rate, so you burn calories even when you're not working out. When it comes to strength training, doing compound exercises is one of the most effective ways to work several muscles at once and save time at the gym. Compound movements like a weighted squat to a shoulder press or a reverse lunge to a bicep curl will work multiple muscle groups, so you get more bang for your buck.
Putting yourself on a very low-calorie diet is a surefire way not to lose. "Your body is programmed to defend your usual weight," says Liz Applegate, Ph.D., professor of nutrition at the University of California at Davis and author of Bounce Your Body Beautiful. "So if you suddenly drop 1,000 calories from your diet, your resting metabolic rate [the number of calories your body burns to maintain basic bodily functions, such as breathing and heartbeat] will automatically slow down, because your body now assumes that you're starving."
Instead of ditching carbs or going low-fat, try a diet that's rich in veggies, beans, and legumes to increase your metabolism — and keep your blood sugar from spiking. "Many people think weight is all about calories in, calories out, but quality also matters," says Aunna Pourang, M.D. "[In a 2012 study], low-carb diets showed the most increase in metabolism, but also showed an increase in the stress hormone cortisol. This is why scientists concluded that the low-glycemic diet worked the best."
Each time you eat, enzymes in your body's cells break down the food and turn it into energy that keeps your heart beating, your mind thinking and your legs churning during a grueling workout. The faster your metabolism runs, the more calories you burn. The more you burn, the easier it is to drop pounds. And get this—you can make your metabolism work harder, a lot harder, 24 hours a day.

But no supplement will speed up your metabolism, no matter what claims it makes. But there are some healthy ways to kick-start your metabolism. To wake up your metabolism, remember to eat breakfast every day. This is a great way to ensure your metabolism gets off to an early start. When you're asleep, your metabolism goes into slowdown mode — by eating breakfast you let your body know that you are up and moving. If you wait to eat breakfast, your body stays in hibernation mode a few hours longer. Also, people who skip breakfast tend to eat more calories throughout the day.

Activity. Aerobic exercise helps you burn calories, and strengthening exercises (resistance training) can help you build and maintain muscle mass. Having more muscle causes you to burn more calories even while at rest (your resting metabolic rate). Keep in mind that building more muscle to burn calories is much more difficult than burning calories through aerobic activities.


Bring on the funny cat videos — they're good for your health, according to researchers. No, you won't get the same calorie-burning results as you get from your spin class, but laughing does give your metabolism a small boost. Astudy published in the International Journal of Obesity found that genuine laughter increased both energy expenditure and heart rate by 10-20 percent above resting values. Another study found that watching cat videos in particular can boost your energy level. Guess you know what you're watching on the treadmill from now on.
If you're someone who loves being cold while they sleep, you might already be doing your metabolism some good. A small study looked at how lowering the temperature while you're catching some zzzs may increase your levels of "brown fat" — the "good" fat that keeps you warm in cold temps by burning calories to generate heat. When the participants in the study slept at 66 degrees opposed to warmer temperatures, their amount of brown fat increased, while the opposite occurred during the months their sleeping areas were warmer. Turns out blasting the AC can really do you some good.
Calcium and vitamin C team up well to boost metabolism. Broccoli contains both nutrients, not to mention the kind of fiber that’s been shown to increase TEF. What’s more: Broccoli contains a compound that works on a genetic level to effectively “switch off” cancer genes, leading to the targeted death of cancer cells and slowing of disease progression.
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!

That doesn't mean you have to live on the high-protein Atkins diet. But you should make sure that 10 to 35 percent of your total daily calories comes from protein. So if you're on an 1,800-calorie diet, 360 to 630 of those calories should come from lean sources of protein, such as fish, chicken, low-fat cheese, yogurt and legumes. "Aim to have a serving of protein, such as nuts, a small can of tuna, or a piece of low-fat string cheese, at every meal and snack," says Hampl.


Eating an apple each day can help prevent metabolic syndrome, a disorder associated with abdominal fat, cardiovascular disease, and diabetes. They’ll keep the doctor away and your muffin tops at bay because apples are a low-calorie, nutrient dense source of fiber, which studies have proven to be integral to reducing visceral fat. A recent study at Wake Forest Baptist Medical Center found that for every 10-gram increase in soluble fiber eaten per day, visceral fat was reduced by 3.7 percent over five years!
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.

Capsaicin, present in spicy foods like chili and red pepper flakes, might boost metabolism by up to 8 percent. As always, don’t use this as an excuse to eat unhealthier foods like greasy takeout. “Sprinkle on red pepper flakes on eggs in the morning,” advises Gans. “You could even make fish, chicken, or lean beef a little spicier for dinner.” Look out for these common foods that are messing with your metabolism.
For nutritionist Lisa Jubilee, one of the best and cheapest ways to give your metabolism a jolt is to drink water (she suggests 20 to 32 ounces) shortly after waking. Why? During sleep, your body’s metabolic function slows down, and unless you wake up in the middle of the night to swig some water, you’re not taking in any fluids. Jubilee suggests completely rehydrating before stressing your body with any other food or drink. “My clients who have implemented this report less bloating, more energy and a smaller appetite,” she says. Her motto for getting your inner furnace stoked and ready for the day: “Rehydrate, then caffeinate!”
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.

"Protein burns more calories than carbs and fat,” says Bustillo. About 30 percent of the calories in protein will go towards digestion and absorption, whereas that number is only about 10 percent for carbs, and even less for fats. Fiber's another nutrient that costs a little more energy, says Bustillo—so, getting adequate protein and fiber can definitely help maximize your BMR.
Muscle is typically more dense than fat and uses more energy as a result. The National Health Service (NHS) in the UK states that those who have a higher muscle to fat ratio tend to have a higher BMR because of the fact it requires more energy to maintain. For every pound of muscle, the body burns 50 calories to maintain a person's BMR. Exercising to build muscle will help boost your metabolism as you get your body in shape.

Probiotics in products like yogurt and fermented foods like pickles and sauerkraut help good bacteria in the gut process food more efficiently. Not only is yogurt a great source of protein and calcium, a Nature study found that eating it as part of a reduced-calorie diet can help shrink your waistline. And you can incorporate it into dishes throughout the day.


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.
Green tea has long been heralded for its antioxidant polyphenols. But new evidence shows the active ingredient, catechin, may crank up metabolism. Researchers conducted a series of studies in dieters and found that those who went green lost more weight than those who didn't, suggesting that catechins may improve fat oxidation and thermogenesis, your body's production of energy, or heat, from digestion. But how much do you have to drink? According to one study, if you drink five eight-ounce cups of green tea a day, you can increase your energy expenditure by 90 calories a day. Sounds like a lot of tea, but it's not hard to do if you also drink it iced.
There are plenty of fish in the sea, but salmon may be the best one for your metabolism. That’s because most cases of underactive thyroid are due to inflammation of the gland, and salmon boasts significant anti-inflammatory properties thanks to its rich omega-3 fatty acid content. In fact, a study in the European Journal of Clinical Nutrition looked at the effects of weight loss and seafood consumption and showed salmon to be the most effective at reducing inflammation—better than cod, fish oil, and a fish-free diet.

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! 

Late night snacking is clearly not recommended, but staying up late in and of itself directly affects the speed of your metabolism. In a study published in Lancet, researchers studied the effects of chronic sleep debt on metabolic and endocrine functions on 11 young men who were restricted to four hours of sleep a night for six nights. The results of the study showed sleep debt negatively impacts carbohydrate metabolism and endocrine function. Researchers concluded that seven to eight hours of sleep a night for adults will help keep your metabolic rate at a healthy, steady pace.

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.
If you really want to speed up your metabolism, start with changes to your daily activity. You'll see the greatest benefit if you can move more throughout the day. Then make diet-friendly food choices that help you to feel more energized. And lastly, skip the metabolism-boosting pills and potions (unless your doctor prescribes it). Most of them don't work and some even cause harm.

This antioxidant-rich, traditional Chinese tea not only helps keep cholesterol levels in check and aids digestion, it can also help rev up your metabolism. Like green tea, oolong is packed with catechins, which boost weight loss efforts by improving the body’s ability to metabolize fat. A study in the Chinese Journal of Integrative Medicine found that participants who regularly sipped oolong tea lost six pounds over the course of six weeks.

Thinking about having a cocktail — or two — before dinner? Think again. Having a drink before a meal causes people to eat around 200 calories more, several studies show. Drinking with dinner isn't such a good idea either: Other research has found that the body burns off alcohol first, meaning that the calories in the rest of the meal are more likely to be stored as fat. If you do have a cocktail craving, stick to wine, which packs only 80 calories a glass — or minimize the calories by drinking a white-wine spritzer (two ounces of wine mixed with two ounces of seltzer).
Fuel your body with wholesome, nutritious foods, and limit your intake of refined carbs (anything sugary or white-flour based). To maximize the calories burned through digestion and stave off hunger, get plenty of complex carbs (fruits, vegetables and beans) and eat a little protein with every meal. It doesn't need to be meat; nuts, lowfat dairy, tofu, and beans are all good vegetarian protein sources. 
Most of your resting metabolism is taken up by your organs—brain, heart, liver, etc. But the biggest factor affecting your metabolism that you can control is your ratio of body fat to lean muscle mass. "Muscle burns more calories than fat tissue, because muscle requires more energy to maintain," says Harold Gibbons, New York State Director of the National Strength and Conditioning Association. "The more fat you have, the slower your metabolism will be."
A good night’s sleep can help balance the fluctuating hormones that wreak havoc after age 50, Katherine explains. Additionally, a well-rested body is more resistant to cravings. “Studies show that when a body is sleep-deprived, the body slows the metabolism to conserve energy,” she says. “This seems counter-intuitive, as we all know it feels like it takes more energy to function when sleep-deprived—but perhaps it is because your own body slowed your metabolism to conserve energy.”

If you vary your diet so that you get more calories once in a while, your metabolism will speed up to meet the need of burning the extra calories without your gaining any weight. Then the next day when you eat less again, your metabolism will still be higher so your body will burn fat to meet the energy needs of the higher metabolic rate. If you add in exercise, you will maintain a higher metabolic rate which will expedite the process even further.
While most of us might wolf our meals down at our desks or in front of the TV, savoring your food may is better for achieving a healthier weight. Recent research shows that the faster people ate, the more they ate because the hormone that signals that you’re full, cholecystokinin (CCK), takes about 20 minutes to kick in. If you inhale your food, you might consume more than you mean to without realizing you’re full. Nutritionist Keri Gans also suggests maintaining a regular dining schedule as an important component to mindful eating habits.
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.

Aim for a breakfast that has plenty of high-fiber carbs: When researchers at the University of Sydney in Australia compared the effects of high-fat and high-fiber-carbohydrate breakfasts, they discovered that people who ate the fatty meal got hungry sooner afterward. "High-fiber carbohydrates take longer for your body to digest and absorb than fats; thus they don't cause rapid changes in your blood sugar, so your hunger is kept at bay longer," says study coauthor Susanna Holt, Ph.D. Some good choices: a bran-rich breakfast cereal with low-fat milk; whole-grain toast topped with low-fat ricotta and sliced banana or berries; an egg-white veggie omelette with whole-grain toast.
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.
