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."
It takes the body extra effort to break down whole grains than more refined and processed grains, like the flour ordinarily used to make bread and pasta. You can help keep your metabolic rate elevated by consuming foods that the body has to work harder to digest. Your go-tos are whole foods that are also rich in fiber. We’re talking brown rice, oatmeal, quinoa, and sprouted grain bread.
Skimping on sleep can derail your metabolism. In a study at the University of Chicago, people who got four hours of sleep or less a night had more difficulty processing carbohydrates. "When you're exhausted, your body lacks the energy to do its normal day-to-day functions, which include burning calories, so your metabolism is automatically lowered," explains Peeke.
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."
Metabolism. It’s the set of life-sustaining chemical transformations within the cells of living organisms. It’s such a big concept that it’s understandable to feel as if it’s beyond your control. But that’s not true! If you’re wondering how to increase metabolism, we’ve rounded up the 55 best quick and easy ways to rev your fat-burning furnace to help you reach your weight loss goals that much faster.
Build muscle mass: Muscle burns more calories than fat, D’Ambrosio says. To be specific, a pound of muscle burns about six calories per day compared to two calories a day for a pound of fat. “If you want your body to burn more calories, you had better build extra muscle mass,” she says. “This is why a person with higher muscle mass will burn more calories and have a higher metabolism at rest than a person with less muscle mass.” Focus on doing resistance or strengthening exercises at least twice a week.
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.
Stephen Colbert’s doing great, but now it’s time to DVR him and start getting to bed earlier. A study in Finland looked at sets of identical twins and discovered that in each set of siblings, the twin who slept less had more visceral fat. If you do nothing else differently, just getting an extra half hour of shuteye will make all the difference. If you’re chronically sleep deprived, don’t be surprised if you gain a few pounds without eating a morsel of extra food. “A lack of sleep can cause several metabolic problems,” says nutritionist Seth Santoro. “It can cause you to burn fewer calories, lack appetite control and experience an increase in cortisol levels, which stores fat.” Lack of sufficient sleep—under the recommended seven to nine hours a night for most adults—also leads to impaired glucose tolerance, a.k.a. your body’s ability to utilize sugar for fuel. “We all have those less-than-adequate nights of sleep,” says nutritionist Lisa Jubilee. “But if it’s a regular thing, you’re better off lengthening your night’s sleep than working out, if fat loss or weight maintenance is your goal.”
Bodybuilders have known for years that strategically placed ‘cheat meals’ can help prevent the metabolic slowdown mentioned above. One meal every five to seven days that contains as many carbs and calories as desired can work. Just make sure not to make a habit out of cheat meals. In fact, you could also just as easily eat clean each day and meet your calorie needs, rather than consistently depriving yourself, then occasionally indulging.
“Any excess protein will be stored in your body as fat, sadly, not as muscle,” Kimberly says. So it’s smart to get your fill. But that doesn’t mean you have to fill up on meat. Remember, plenty of plants and legumes are loaded with protein, too, such as beans, broccoli, and asparagus. “A good plant-based diet will also provide your body with the necessary fiber to keep the system running smoothly,” Kimberly says. Isabel Smith, M.S. R.D., celebrity dietitian, and fitness expert, suggests also starting your day with protein to help balance your hormones and blood sugar level from the get-go.
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.
"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.
