Frequently Asked Questions
Pro Tips
Body fat percentage, not BMI, determines whether you're overfat. Someone with 30% body fat at "normal" BMI (skinny fat) has the same metabolic risk as an overweight person.
The Navy method used here has a ±3-4% margin of error. DEXA scans are most accurate but expensive — good for periodic validation, not daily tracking.
Reducing body fat while maintaining muscle mass (recomposition) is the goal — not just weight loss. Track body fat %, not weight, to confirm you're losing fat not muscle.
Men below 6% and women below 14% body fat reach essential fat levels needed for organ function — do not target these for general health and fitness goals.
When to Use This Calculator
Measure body fat percentage at baseline before a diet and training program to track fat loss vs muscle gain.
Check body fat percentage monthly to confirm fat loss progress, especially if weight on the scale isn't changing.
Find your current body fat percentage and set a realistic target (e.g., reach athlete category for your sex).
Estimate body fat before a military, fire department, or athletic physical where body composition standards apply.
Calculate body fat alongside BMI to get a complete picture when BMI alone gives a misleading result.
