Frequently Asked Questions

How does the Navy method body fat calculator work?
The U.S. Navy method estimates body fat percentage using circumference measurements — neck, waist, and hips (for women). The formula was developed by Hodgdon and Beckett and correlates within 3-4% of hydrostatic weighing for most people. It is the most accessible field method that does not require specialized equipment.
What is a healthy body fat percentage?
For men, 10-20% body fat is generally considered the fitness range, with 6-13% being athletic and above 25% classified as obese. For women, 18-28% is the fitness range, 14-20% is athletic, and above 32% is classified as obese. Essential fat is approximately 2-5% for men and 10-13% for women.
Is body fat percentage more useful than BMI?
Yes, body fat percentage distinguishes between fat mass and lean mass, which BMI cannot do. A muscular person may have a high BMI but a low body fat percentage. Body fat percentage is a more accurate indicator of metabolic health, cardiovascular risk, and physical fitness than BMI alone.
How does Vora track body composition over time?
Vora integrates data from smart scales, wearables, and manual measurements to track body fat trends over weeks and months. It correlates body composition changes with your nutrition, training load, and recovery data to show you what is actually moving the needle.
