Why Body Fat Percentage Matters
Body fat percentage is a more meaningful health metric than weight or BMI alone. It distinguishes between fat mass and lean mass (muscle, bone, organs), allowing a clearer picture of fitness and health risk.
US Navy Method (Used Here)
This method uses circumference measurements and height:
Men: %Fat = 86.010 × log10(waist − neck) − 70.041 × log10(height) + 36.76
Women: %Fat = 163.205 × log10(waist + hip − neck) − 97.684 × log10(height) − 78.387
Measurements in centimeters or inches (consistent units required).
Body Fat Categories
| Category | Men | Women |
|---|---|---|
| Essential fat | 2–5% | 10–13% |
| Athletes | 6–13% | 14–20% |
| Fitness | 14–17% | 21–24% |
| Average | 18–24% | 25–31% |
| Obese | 25%+ | 32%+ |
How to Measure Accurately
- Waist: Measure at the narrowest point (or navel level for men)
- Hips: Measure at the widest point (women only)
- Neck: Measure just below the larynx, sloping slightly forward
- Use a soft measuring tape, pulled snug but not compressing the skin
Limitations
Circumference measurements are less accurate than DEXA scans or hydrostatic weighing, but they are practical for home use. Accuracy can vary by ±3–4%.
