Frequently asked questions
How is body fat percentage calculated?
The US Navy method uses neck, waist, and hip circumferences with height and a logarithmic formula. It's practical and reasonably accurate (±3–4%) without special equipment.
What is a healthy body fat percentage?
For men: athletic 6–13%, fitness 14–17%, average 18–24%, obese 25%+. For women: athletic 14–20%, fitness 21–24%, average 25–31%, obese 32%+.
Is body fat more important than BMI?
Body fat % is a better indicator of health risk than BMI because it distinguishes muscle from fat. A muscular person can have a high BMI but healthy body fat. Use both together.
