The US Navy method uses circumference measurements and is a widely accepted estimation. For more accurate results, consider DEXA scanning or hydrostatic weighing. Consult a healthcare professional for personalized advice.
Frequently Asked Questions
What is a healthy body fat percentage?
For men, 10–20% body fat is considered healthy (athletes: 6–13%, fitness: 14–17%). For women, 18–28% is healthy (athletes: 14–20%, fitness: 21–24%). Essential fat (needed for basic functions) is 2–5% for men and 10–13% for women.
How does the US Navy body fat method work?
The US Navy method estimates body fat using circumference measurements. For men, it uses neck and waist circumference. For women, it adds hip circumference. The formula uses logarithmic calculations and has been validated to be accurate within 3–4% of DEXA scan results.
Which body fat measurement method is most accurate?
DEXA (dual-energy X-ray absorptiometry) is the gold standard, accurate to within 1–2%. Hydrostatic weighing and Bod Pod are also very accurate. The US Navy method and BMI-based estimates are convenient but less precise. Bioelectrical impedance (smart scales) can vary significantly based on hydration.
