Ever wonder why your best friend can go through a pint of Ben & Jerry's without gaining a pound while just one spoonful goes straight to your hips? The answer lies in your metabolism, that little engine in your body that burns calories all day, every day. Because of genetics, some women burn fat faster than others. But age, weight, diet, and exercise habits also play a role.
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.”
Some things, though, aren’t that simple. For instance, someone with a higher metabolism burns more calories at rest than someone with a lower metabolism, and can therefore get away with eating more food—even junk food. But a high metabolism isn’t a privilege reserved for a select few lucky enough to be born with it. You can raise yours and reap the benefits, too.
But there are easy things you can do to stoke your fat-burning potential. "There's no reason you can't have the same metabolism in your 30s and 40s that you had in your 20s," stresses Pamela Peeke, M.D., author of Fight Fat After Forty. Here are some experts' tips on how to boost your metabolism — so you, too, can guiltlessly binge on Ben & Jerry's every now and then.
If you always opt for coffee over tea, you could be missing out on a major metabolism boost. A Penn State animal study found supplementing exercise with green tea can actually boost weight loss. In fact, after 16 weeks, rats experienced a body mass reduction of 27.1 percent and an average abdominal fat mass reduction of 36.6 percent. What’s its magic? The brew contains catechins, a type of antioxidant that triggers the release of fat from fat cells and helps speed the liver’s capacity for turning fat into energy.
The easiest 350 calories you'll ever burn: Exercise is obviously important, but regular daily activity known as "NEAT" (nonexercise activity thermogenesis) is equally essential for a healthy metabolism. Small movements such as stretching your legs, taking the stairs, even just standing to talk on the phone increases your energy expenditure and can add up to an extra 350 calories burned a day.
