Body composition refers to the proportion of fat and non-fat mass in the body. It provides a more detailed understanding of health than simply looking at weight alone. The key components of body composition include fat mass, lean body mass, muscle mass, water, and bone density.

Choosing fat as the part of body composition recognizes the essential role it plays alongside other components. Fat is not merely a source of energy but also serves important physiological functions, such as insulation, hormone production, and protection of vital organs. Understanding body composition requires looking at both the fat and lean mass to evaluate overall health and fitness properly.

Height is simply a measurement without bearing on body composition, while muscle mass alone does not encompass the entirety of body composition, as it excludes the fat component. Lastly, age, while it may influence body composition to some degree, is not a direct measure of composition itself. Therefore, identifying fat as an essential aspect of body composition is crucial in health assessments and fitness evaluations.
