Our metabolism is at work every time we breathe, circulate blood, or digest food, providing energy for these basic body functions. While our metabolism is always active, the rate at which it works varies depending on a variety of factors such as our age, weight, and activity level. Someone who is younger and more active, for example, will have a higher metabolic rate than someone who is older and less active.We can increase our metabolism by eating smaller, more frequent meals and exercising on a regular basis. We can help keep our bodies healthy and fit by keeping our metabolism running smoothly.
