About Body Fat Calculator
How It Works
Body fat percentage is estimated using the US Navy circumference method, which uses measurements of height, neck, waist, and hip circumference. The formula calculates body density and converts it to a body fat percentage estimate.
How to Interpret Results
Essential body fat ranges from 10-13% for women and 2-5% for men. Healthy ranges are 14-31% for women and 6-24% for men, varying by age. Higher percentages may indicate excess fat storage and increased health risk.
Health Tips
Combine strength training with cardiovascular exercise to improve body composition. Focus on body fat percentage rather than scale weight for a truer picture of fitness progress. Adequate protein intake supports muscle preservation during fat loss.
Limitations
Circumference-based estimates have a 3-4% margin of error. Results vary with measurement technique, hydration status, and time of day. DEXA scans or hydrostatic weighing provide more accurate measurements.
