About Body Fat Percentage
Body fat percentage calculators are widely used in fitness and health assessment to determine the amount of fat in an individual's body compared to other tissues. Fitness enthusiasts and athletes use this metric to track progress during training programs, as it provides more meaningful insights than weight alone.
Healthcare professionals use body fat percentage as a more accurate health risk assessment tool than BMI, particularly for individuals with higher muscle mass. Personal trainers use these measurements to create tailored fitness and nutrition plans.
