Increase Your Metabolism
Simply put, metabolism is the process of breaking down proteins, carbohydrates, and fats to yield the energy your body needs to maintain itself. The rate of your metabolism depends on the interaction between the number of calories you consume, the number of calories you burn while eating and exercising, and the calories you burn based on your individual genetic makeup.
How can you increase your metabolism? Well, there’s not much you can do about your genes (they only account for a measly 5% of total daily calorie consumption anyway), which means the best way to rev up your metabolism is to increase your body’s need for energy.
“Your body can burn calories from either fat, protein, or carbs,” says John Berardi, PhD, CSCS, president of Precision Nutrition, and author of The Metabolism Advantage. “Of course, you’d rather it burn fat calories, but your body isn’t wasteful; it will burn fat only when it needs energy.”
One such time is during exercise, but it’s difficult to exercise all the time, especially if you’re stuck at a desk all day. Luckily, your body requires extra energy at other times, too, such as during the first hour or two after intense exercise like interval training and weight lifting. This is called the “afterburn” effect, Berardi says, and it can last for up to 24 hours. Strength training with heavier than usual weights uses up energy, too -- in order to repair small (healthy) muscle tears.
And simply being more muscular boosts your body’s energy needs. Each extra pound of muscle you carry can burn up to 50 additional calories just to maintain itself -- and with no effort on your part. You can also increase your metabolism by eating foods that require extra energy to digest and metabolize; for example, protein. Your body burns twice as many calories digesting high-protein foods as it does foods that are high in carbs or fat, he says.
