📐 About the US Navy Method
The US Navy Body Composition method is a scientifically validated technique developed by the Department of Defense. It uses circumference measurements to estimate body fat percentage.
Accuracy: The Navy Method has a margin of error of ±3-4% when compared to more advanced methods like DEXA scans or hydrostatic weighing.
⚠️ Important Notes
- •Take measurements at the same time of day for consistency (morning is best)
- •Measure on bare skin, not over clothing
- •Keep the tape measure snug but not tight - don't compress the skin
- •Take multiple measurements and use the average for better accuracy
- •This method may be less accurate for very lean or obese individuals
- •Track trends over time rather than focusing on a single measurement
