Explanation: The equation accounts for the relationship between body circumferences and height to estimate body fat percentage.

3. Importance of Body Fat Measurement

Details: Body fat percentage is a better indicator of health than weight alone. It helps assess fitness level, health risks, and progress in weight management programs.
