What Is Body Fat Percentage?
The US Navy method estimates body fat percentage from circumference measurements: height, neck, waist, and (for women) hip. Measurements should be taken at consistent points (e.g. waist at navel, neck at narrowest). The result is an estimate, not as accurate as DEXA or calipers by a trained provider, but useful for tracking trends at home. Healthy ranges vary by sex and age; consult a healthcare provider for personal targets.
