What is Body Composition? Calculating Body Fat Percentage

Weight is often considered a good indicator of overall health and well-being. While it’s true that you can reach an optimal and healthy weight, going by weight alone is not an accurate way to determine how healthy you are. The number you see on the scale might tell you how much your body weighs, but it doesn’t tell you what comprises that weight. How much of that is fat? How much is muscle? What is your body’s composition? 
Body composition is the ratio of your body’s fat to all other mass in your body--that which is composed of muscles, organs, bone, and water weight. Bone and organ weight generally remain relatively constant, but fat and muscle weight may fluctuate. The percent of your body that is composed of fat is a more important indicator of your overall health and fitness than weight alone. 
In this guide, we’ll discuss the different ways body composition is measured, and how calculating your body fat percentage can give you deeper insights into your overall health.
