Frequently Asked Questions
What is a healthy body fat percentage?
For men: 10-20% is athletic/fit, 18-25% is average. For women: 18-28% is athletic/fit, 25-31% is average. Essential fat is 2-5% (men) and 10-13% (women).
How accurate is the Navy method?
The Navy method is reasonably accurate for most people (within 3-4% of DEXA). It's less accurate for very muscular or very lean individuals.
Where should I measure for body fat?
Measure at the narrowest part of your waist (usually at navel level), widest part of your hips, and around your neck just below the larynx.
Why is body fat percentage important?
It's a better health indicator than weight alone. Two people at the same weight can have very different body compositions and health risks.
