Frequently asked questions
- How accurate is the Navy method?
- Studies put the margin of error at ±3–4% compared with DEXA. It is less accurate for very lean or very obese individuals.
- Where do I measure the waist?
- For men: at the navel. For women: at the narrowest point. Keep the tape level and breathe normally — don't suck in.
