About Body Fat Percentage

Body fat percentage is the proportion of your body weight that is fat tissue. Women naturally carry more essential fat than men for hormonal and reproductive health. The US Navy method uses circumference measurements and is reasonably accurate for most people. For precise measurement, consider DEXA scanning, hydrostatic weighing, or professional bioelectrical impedance analysis.
