Managing Metabolism with Aging
People think that because they age they automatically have a slower metabolism than when they were younger. Your metabolism works off two main things: genetics and lean muscle mass. If your parents were lethargic/athletic/ping-pong pros, you will be more disposed to lead that kind of life based upon your genetics. Not all people are that way though. The main reason metabolism slows with age is based upon your lean body mass. When you're younger you move more, and as people get older they move less. Therefore, the lean body mass of an individual will decrease unless they continue exercising or begin to exercise more. Also, if you have very little lean muscle mass then you will not burn as many calories in a day as someone who has lots of muscle mass. If you want to make sure your metabolism doesn't slow as you begin to age then change your diet, exercise and move to stay in shape, keeping that lean muscle mass in check.
