The Navy formula is a logarithmic equation that uses simple tape measure circumferences to estimate density. It is highly regarded as the most accurate at-home testing method available without medical equipment.
Bonnes Pratiques & Conseils
- Measure Under Consistent Conditions: The human body fluctuates in water retention daily. Always take circumference measurements first thing in the morning, on an empty stomach, after using the bathroom.
- Ensure the Tape is Level: A crooked tape measure will artificially inflate the measurement. Ensure the tape is perfectly horizontal across your naval and resting firmly against the skin without compressing the tissue.
- Track the Trend, Not the Number: While the Navy formula is accurate to roughly ±3%, it is an estimate. If the calculator says you are 18%, you might actually be 16% or 20%. The true value of the tool is tracking the downward trend over time.
