Body Composition is a term used to describe the different components that together make up a person's body weight. "Lean" tissues, such as muscle, bone, and organs are metabolically active, while adipose (fat) tissue is not. Several methods exist for assessing the percentage of fat and lean mass of an individual. These methods are referred to as Body Composition Analysis. Body composition analysis can be beneficial for a number of reasons. If one has too much fat — especially if predominantly located in the waist — there is a higher risk for such health problems as high blood pressure, high blood cholesterol and diabetes, which increases risk for heart disease and stroke.
