What is body composition?

Body composition refers to the proportions of different components that make up an individual's body, specifically focusing on fat mass and non-fat mass (which includes lean mass such as muscles, bones, organs, and water). It provides a more comprehensive understanding of body health than just body weight, as it accounts for the various tissues and substances that comprise the body.

The correct answer is significant because it highlights the importance of knowing not just how much a person weighs, but what that weight consists of. A person can weigh the same as another individual but have very different health profiles depending on their muscle and fat distribution. By understanding body composition, individuals can make informed decisions about fitness, nutrition, and overall health.

The concept of body composition is essential in fitness and health assessments, as it aids in goal-setting for weight loss or muscle gain while ensuring that individuals maintain a healthy ratio of fat and lean tissue.
