21 Ways to Burn Fat Faster part 5

Snack away during the day
Grazing is a surprisingly good idea because it helps you avoid metabolic slowdown. "Your body will be tricked into thinking it's constantly eating, so it will never slow your metabolism down," explains Bauer. Aim for five small meals (200 to 500 calories) a day rather than three large ones. Also try not to go more than four hours without eating -- if you eat breakfast at 7am, for example, have a snack at 10am, lunch at noon, another snack at 3pm and dinner at 7pm.

Skip the starch
Carb crazy? Consider this: Refined carbohydrates, such as bread, potatoes and rice, create a surge in insulin that in turn drives down your resting metabolic rate, explains Aronne. "It's important to keep carbohydrates in your diet, but really focus on fruits, vegetables and whole grains, which have less of an effect on insulin levels," he explains. And when buying whole-grain breads and cereals, make sure the first ingredient listed is whole wheat, whole oat or cracked wheat.

Break up your workouts
Try dividing your workouts into two shorter 20-minute sessions. You'll rev up your metabolism for an hour or two after each workout, which means you'll burn more calories than if you did one longer session. Don't have time? Even small bursts of activity will get your metabolism chugging again, according to a study in Nature. "Just a five-minute walk around the house every hour translates into an extra 200 to 300 calories burned every day," says Peeke.

Pace while you're on the phone
People who are constantly in motion -- crossing and uncrossing their legs, stretching and pacing -- burn more calories. When researchers at the Mayo Clinic asked subjects to eat an additional 1,000 calories a day for eight weeks, they found that only the nonfidgeters stored the calories as fat.
