Frequently Asked Questions
How accurate is the US Navy method?
The US Navy method is considered one of the most accurate non-invasive methods for estimating body fat percentage. It's used by the military and provides results within 3-4% of more expensive methods like DEXA scans.
Why do men and women have different body fat ranges?
Women naturally have higher body fat percentages due to biological differences including reproductive functions, hormonal differences, and body composition. Essential fat levels are higher in women to support these functions.
How often should I measure my body fat?
Body fat percentage changes more slowly than weight. Measuring every 2-4 weeks is sufficient to track progress. Focus on trends over time rather than daily fluctuations, and always measure at the same time of day for consistency.
