Which of the following statements about body composition is correct?

Body composition is a multifaceted concept that encompasses the various components that make up a person's body, primarily including the proportions of fat mass and lean mass. This terminology refers not only to muscle mass but also to fat, bone, and water content. The correct statement emphasizes that body composition includes body fat percentage and lean mass, providing a more accurate and comprehensive understanding of an individual’s physical makeup.

Understanding body composition is crucial because it helps to reflect a person's fitness level and potential health risks more accurately than weight alone. For example, two individuals may weigh the same but have significantly different body compositions, leading to different health implications.

This concept directly links to overall wellness, as a higher percentage of lean mass relative to body fat is generally associated with better metabolic health and physical function. Hence, recognizing both lean mass and body fat percentage as integral components of body composition is vital in assessing health and fitness.
