You know your weight, but do you know what that weight is comprised of? Body composition tells you how much of your weight is made up of lean mass (muscles, bones, organs) and how much is fat. To truly understand your level of health it’s important to know how much fat you have.
Just knowing your body weight can be a deceptive measurement of your overall health. For example, an athlete may way 225 pounds but have 15% body fat. An average person may weigh 225 pounds but have 25% body fat. Clearly there is a difference in the physical fitness and health of the two. Just having them stand on a scale wouldn’t reveal the difference though.
Taking part in a fitness program that involves both diet and exercise will help reduce your body fat percentage. Losing weight typically involves losing both lean mass and fat mass, so be sure to add strength training to your regimen to build back the muscle mass.
