Everyone's body works differently, and everyone will have a different metabolic rate. The trick is to figure out how fast or slow your metabolism is -- that's called your Basal Metabolic Rate (BMR) -- and then tailor your caloric needs and amount of exercise to suit how your body works
BMR is an important piece of how to work with your metabolism to lose weight because it measures how many calories you burn when you're doing nothing. (Remember, even when you're not active, your body is still using energy for breathing and other basic functions that keep you alive.) It's calculated based on your age, gender, height and weight factors.
