Eat plenty of healthy fats. Healthy fats like avocados, nuts and seeds, along with wild, fatty fish are your mitochondria’s preferred fuel. My favorite “gasoline” for your mitochondria is medium-chain triglycerides or MCT oil, which is found in coconut oil. I provide an extensive plan to utilize these and other healthy fats in my new book Eat Fat, Get Thin.
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.
Iron deficiencies can slow down your metabolism. Do you know what’s got plenty of it? Lean meat. Eating three to four daily servings of iron-rich foods will help keep your inner furnace burning. Fortified cereals, dried fruit, and dark leafy greens will get you on your way to meeting your iron goals, but lean meat—with its high muscle-building protein content—will be doubly useful in revving up your metabolism.
Move more and faster. Research shows high intensity interval training (where you go all out for 30 to 60 seconds, slowing down for a couple of minutes, and repeating) coupled with strength training is an excellent way to make new, improved mitochondria. Strength training builds muscle and creates more mitochondria, while interval training improves mitochondrial function and how quickly they burn oxygen and calories.

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!”
You can even increase your metabolism while sleeping, which is welcome news to those of us who walk around tired all of the time. How? By lowering the temperature of your bedroom at nighttime and getting ample sleep regularly so you have more energy during the day. Do these nine things and get your metabolism working for you so you reach your weight loss goals quicker than ever
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 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.
So how many calories should you consume? Depending on your level of activity, you can safely lose anywhere from half a pound to two pounds a week if you multiply your current weight by 11, says Applegate. (For example, if you're 120 pounds, aim for around 1,320 calories a day.) Unless you're less than five feet tall, don't let your daily calories dip below 1,200. "Research shows that women who consume less than this amount see their resting metabolic rate plummet by as much as 45 percent," notes Dale Huff, R.D., a St. Louis nutritionist.
Drinking an ice cold glass of water with greater frequency can boost your metabolism. In a study conducted at the University of Utah, researchers found that drinking eight 8-ounce glasses of water a day can be effective to promote a fast metabolism. The participants of the study were given four, eight or twelve 8-ounce glasses of water a day. On the fifth day before they began their day, they were connected to a machine that would determine how many calories they burned per minute while they were resting, along with monitoring urine concentration and blood indicators to decipher their hydration levels. The results of the study showed those who consumed four glasses of water a day as opposed to eight were significantly more dehydrated and reported lower, or slower metabolic rates. Researchers suggest that eight to twelve 8 ounce glasses of water daily will prompt higher metabolic rates in individuals.
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.
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.”
Even the fittest and most health-conscious people can’t avoid aging. And while, there’s nothing wrong with adding years of experience and memories under your belt, sometimes age adds a bit more than that. Plenty of factors contribute to increased weight over time, but decreased metabolism is a main culprit. In fact, even if you continue with your regular eating and exercise plan every year, you’ll still gain two pounds per year, says Kimberly Corp, certified Pilates instructor, and co-founder of Pilates on Fifth. The good news is that you still have a lot of control over your metabolism after 50. Here are some expert tips to help rev up your engines.
As far as foods and supplements go, nothing's been shown to have a meaningful impact on metabolic rate. "Green tea has a reputation for being a metabolism booster because it has compounds like caffeine, but the effect is so tiny, it's negligible," Sasso says. Protein also gets branded as metabolism-boosting, because the body uses more energy to digest it than it does for fat and carbs. But this effect is only temporary and, again, not big enough to make a real difference on its own.
