Frequently Asked Questions

What method does this use?
The US Navy body fat estimation method, which uses neck, waist (and hip for women) circumference measurements with height.
How accurate is this method?
The Navy method is within 3-4% of DEXA scan results for most people. It's one of the most reliable non-clinical methods.
Where should I measure?
Neck: below the larynx. Waist: at the navel. Hip (women): at the widest point. Measure in the morning before eating.
What is a healthy body fat percentage?
Men: 10-20% is healthy. Women: 18-28% is healthy. Athletes are lower, and essential fat should never be eliminated.
How often should I measure?
Every 2-4 weeks at most. Body fat changes slowly. Measure at the same time of day for consistency.
