Think of every bean as a little weight-loss pill. One study found that people who ate a ¾ cup of beans daily weighed 6.6 pounds less than those who didn’t—despite bean eaters consuming, on average, 199 calories more per day. The magic is in the perfect combination of protein and fiber: Studies show that those who eat the most fiber gain the least weight over time and that eating fiber can rev your fat burn by as much as 30 percent. Aim for about 25 grams of fiber a day—the amount present in about three servings each of fruits and vegetables.
Whenever possible, slice each of your workouts into two smaller sessions. For example, do a 15-minute weight-lifting session in the morning, then do your 30-minute walk on your lunch hour or at night. You'll burn an extra 100 to 200 calories that day, explains Kelly Tracy, M.A., fitness coordinator at Duke University Diet and Fitness Center. Don't have time? Just add in some stair climbing or short walks throughout the day. Even small bursts of activity are enough to get your metabolism revved, according to a study in the scientific journal Nature. "I call it the mini stoke: For five minutes out of every hour, get up and do something, even if it's just walking around your office," says professor of medicine Peeke. "You can end up burning a couple of hundred extra calories.
Research shows that getting plenty of protein can boost your metabolism, causing you to burn an extra 150 to 200 calories a day, says Jeff Hampl, Ph.D., R.D., a spokesman for the American Dietetic Association. "Protein is made up mainly of amino acids, which are harder for your body to break down [than fat and carbs], so you burn more calories getting rid of them," he explains.
Going organic can be costly and leave a dent on your wallet, but it can speed up your metabolism. The antibiotics and growth hormones found in conventionally farmed foods could hamper your immune system and slow down metabolism. The amount of pesticides in non-organic foods can cause a above normal dip in metabolism in dieters who begin to lose weight, says Prevention.com.
In one study published in the American Journal of Epidemiology, volunteers who got 22 to 55 percent of their total calories at breakfast gained 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.
When you're trying to ramp up your metabolism, eating fats might sound scary — but you just have to eat the right kind. Focus on a balanced diet of protein, carbs, and healthy fats like avocados, nuts, and olive oil to see a change. "I told my friend to start her day with high-fiber cereal, plain yogurt, and a handful of walnuts, or a hard-boiled egg and a slice of whole-grain toast topped with avocado. Then eat this same balance of protein, carbs, and fat for lunch and dinner," says Eugenia Gianos, M.D., co-director of the Center for the Prevention of Cardiovascular Disease at New York University Langone Medical Center. "She felt full between meals, had fewer cravings, and because good fats and fiber work in tandem to boost metabolism, she was able to drop the extra pounds and keep them off. It's a strategy I've seen work over and over again in my practice."
Buying organic fruits and veggies might cost a little bit more, but it's worth it for your waistline. Researchers in Canada found those with the most organochlorines — AKA pollutants found in pesticides that are stored in fat cells — are more likely to experience a halt in metabolism opposed to those who eat pesticide-free organic produce. To avoid letting what you eat get in the way of burning more calories, try to at least buy organic produce when it comes to the Environmental Working Group's "Dirty Dozen": strawberries, spinach, nectarines, apples, peaches, pears, cherries, grapes, celery, tomatoes, sweet bell peppers, and potatoes.
Most of us choose one time of day to get our exercise in—whether that’s first thing in the morning or right after work. Though having a routine is helpful, Katherine suggests incorporating physical activity into both morning and night. For example, if you typically only exercise in the morning, then do a little something in the afternoon or early evening to bring the heart rate back up for a bit. “Evening exercisers can do the same thing in the morning,” she says. “Ten to 15 minutes of some activity in the morning will jump-start your metabolism for the day and will do a world of good.”

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.
Make sure you eat breakfast. Eating a nutrient-rich morning meal (like oatmeal with almonds and berries, or a spinach-and-feta omelet with a slice of whole-grain toast) shortly after getting out of bed literally wakes up your metabolism. "Eating breakfast gets the engine going and keeps it going," Hyman explains. It's hard to argue with these results: According to the National Weight Control Registry (an ongoing study that tracks 5,000 people who lost an average of 66 pounds and kept it off more than five years), 78% of those who keep it off eat an a.m. meal every day.
As the endocrine system controls the rate and direction of metabolism, what you consume and your level of physical activity will overall influence the speed of your metabolism and how much you weight you gain. The belief that your metabolism is to blame for increased fat is not correct. Eating more calories than you can burn is the primary cause. The best way to control how many calories you burn is through your level of physical activity, according to the Mayo Clinic. What appears to be a faster metabolism in others is more often a more active lifestyle, that leads to weight loss or maintaining a steady weight.
