Frequently Asked Questions

What is a healthy body fat percentage?

For men, essential fat is 2–5%, athletic range is 6–13%, fitness range is 14–17%, and average is 18–24%. For women, essential fat is 10–13%, athletic is 14–20%, fitness is 21–24%, and average is 25–31%. Above 25% (men) or 32% (women) is generally considered obese.

How accurate is the Navy method?

The U.S. Navy body fat formula uses neck, waist, and hip measurements to estimate body fat. Studies show it's accurate within 3–4 percentage points for most people — sufficient for tracking trends. It's less accurate for very muscular individuals and those with unusual fat distribution patterns.

What is a healthy waist-to-hip ratio?

For men, a WHR below 0.90 is considered low health risk. For women, below 0.80 is low risk. Ratios above 1.0 for men or 0.85 for women indicate significantly increased cardiovascular risk.

Is waist-to-hip ratio better than BMI?

WHR is a better predictor of cardiovascular disease risk than BMI because it accounts for fat distribution. Central obesity (apple shape) carries more health risk than peripheral fat storage.
