Eat (a good) breakfast
Every. Single. Day.
If you don’t, your body goes into starvation mode (it’s paranoid like that), so your metabolism slows to a crawl to conserve energy, Berardi says. And the heartier your first meal is, the better. In one study published in the American Journal of Epidemiology, volunteers who got 22 to 55 percent of their total calories at breakfastgained only 1.7 pounds on average over four years. Those who ate zero to 11 percent of their calories in the morning gained nearly three pounds. In another study published in the same journal, volunteers who reported regularly skipping breakfast had 4.5 times the risk of obesity as those who took the time to eat.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.
Guzzle your water cold
Chase your morning joe with an ice-cold glass of H2O. Researchers at the University of Utah found that volunteers who drank eight to 12 eight-ounce glasses of water per day had higher metabolic rates than those who quaffed only four glasses. Your body may burn a few calories heating the cold water to your core temperature, says Madelyn Fernstrom, Ph.D., founder and director of the University of Pittsburgh Medical Center Weight Management Center. Though the extra calories you burn drinking a single glass doesn’t amount to much, making it a habit can add up to pounds lost with essentially zero additional effort.
Brew up some green tea
“It’s the closest thing to a metabolism potion,” says Tammy Lakatos Shames, R.D., author of Fire Up Your Metabolism: 9 Proven Principles for Burning Fat and Losing Weight Forever. The brew contains a plant compound called ECGC, which promotes fat burning. In one study, people who consumed the equivalent of three to five cups a day for 12 weeks decreased their body weight by 4.6 percent. According to other studies, consuming two to four cups of green tea per day may torch an extra 50 calories. That translates into about five pounds per year. Not bad for a few bags of leaves, eh? For maximum effect, let your tea steep for three minutes and drink it while it’s still hot.
Mix things up with intervals
You’re always looking for a way to shorten your workout, right? Well, step up your intensity and you’ll burn the same number of calories or more in less time. In one Aus tralian study, female volunteers either rode a stationary bike for 40 minutes at a steady pace or for 20 minutes of intervals, alternating eight seconds of sprints and 12 seconds of easy pedaling. After 15 weeks, those who incorporated the sprints into their cardio workouts had lost three times as much body fat—including thigh and core flab—compared with those who exercised at a steady pace. Bursts of speed may stimulate a fat-burning response within the muscles, says lead researcher Ethlyn Gail Trapp, Ph.D. Whether you ride, run, or row, try ramping things up to rev your burn: Start by doing three eight-second all-out, can’t-talk sprints with 12 seconds at an easy pace between each effort. Work your way up until you can do 10 sprints over 20 minutes.
Take it slow
This isn’t easy, but when you strength train, count to 3 as you lower the weight back to the start position. Slowing things down increases the breakdown of muscle tissue—yeah, it sounds bad, but all that damage you’re incurring is actually a good thing. The repair process pumps up your metabolism for as long as 72 hours after your session, according to researchers at Wayne State University. But pass on those featherweight dumbbells—you need to use weights that are heavy enough that you struggle to complete the final few reps.
Hit the sack- early
When you sleep less than you should, you throw off the amounts of leptin and ghrelin—hormones that help regulate energy use and appetite—that your body produces. Researchers at Stanford University found that people who snoozed fewer than 7.5 hours per night experienced an increase in their body mass index. So make sure you get at least eight hours of rest.
