This is an estimate, not a diagnosis. DEXA and other lab methods are more accurate. Use the number to track trends, not to label your body.

Frequently asked questions
+How accurate is the US Navy method?
Usually within a few percentage points for most adults. It works best for tracking changes over time.
+Where do I measure?
Neck just below the larynx. Waist at the narrowest point (or at the navel for men). Hip at the widest point.
+Is this a medical assessment?
No. It's a rough estimate. Speak to a clinician for a proper body-composition assessment.
