Dehydrated cells and organs don’t function as well as they should, leaving your metabolism lower than it could be if you’re not fully hydrated. Water is best, but you can also increase your hydration levels by consuming other beverages too. Just make sure they don’t have high calorie or sugar levels. (This suggestion works especially well for college students who hope to avoid the Freshman 15!)
Have a few cups of java for a metabolism boost, but if you’re never seen without a mug at your lips, that could work against you, says nutritionist Amy Shapiro. Caffeine is a natural appetite suppressant. If you’re constantly consuming it, you may not eat much—or realize how hungry you really are—until you get home for dinner. “Not eating enough throughout the day can make your metabolism sluggish,” she says. “By the time you eat dinner, instead of immediately using that food for energy, your body is aggressively storing it as fat, just in case it will be deprived again.”
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.
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.
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.
Lifting weights: Strength training builds muscle, and Marci says, "The more muscle mass you have, the more calories you will burn, even while at rest." While doing cardio does burn calories, your body quickly adapts to the amount you do, so in order to burn the same number of calories, you'll have to do more cardio. Lifting weights saves you time and is way more effective.
You might want to think twice before ditching dairy if you’re trying to lose weight—despite what your Paleo-preaching CrossFit friends tell you. Cheese is a satisfying, portable, and inexpensive food that’s packed with calcium, vitamin D, and protein. “Calcium can also promote weight loss because it helps maintain muscle mass, which boosts and helps maintain metabolism, helping you burn calories more efficiently throughout the day,” says Tanya Zuckerbrot, RD, author of The Miracle Carb Diet: Make Calories & Fat Disappear—With Fiber! That doesn’t mean you can help yourself to a cheese-drenched casserole, though. Work cheese into fiber-rich snacks to make them more satiating.
While drinking in moderation every so often won’t do too much harm to your waistline, making it a habit can slow down your metabolic rate. Why? When your body has a cocktail to break down, it takes precedence over any food that you’ve already eaten that’s waiting to be digested. This slows down the entire metabolic process. On the occasions that you decided to indulge, stick to low-calorie drinks. Alternate your alcohol with water to slow your pace, and cut yourself off after two drinks. Avoid ordering high-cal bar food like fries and burgers. An important note: Wine in moderation can have numerous benefits, including weight loss!
Eat six small meals a day to avoid blood-sugar spikes and minimize urges to binge. Try to schedule meals at the same time each day. If you feed yourself well throughout the day, you'll learn to understand when your body truly needs food. You can't starve yourself and expect to make good choices at the next meal.

It’s like butter that grows on trees. But instead of the cholesterol, trans fats, and saturated fats in real butter, avocado contains metabolism-enhancing monounsaturated fat. And that’s not all. Each creamy fruit is also packed with fiber and free-radical-killing antioxidants. Free radicals are destructive rogue oxygen molecules—natural byproducts of metabolism—that trigger various chain reactions in the body that destroy cells and DNA, causing all kinds of health problems. Antioxidants in fresh fruits and vegetables can help neutralize some free radicals, but they can’t reach the mitochondria—the base camp for the free radical army—and that’s a problem. When your mitochondria aren’t working properly, your metabolism runs less efficiently. Enter: Avocado. A 2015 study found that monounsaturated-rich oil pressed from the fruit can help mitochondria become more resilient. Researchers say the results jive with low-disease rates in Mediterranean countries where olive oil—nutritionally similar to the avocado—is a diet staple.
