How It Calculates the Results
The calculator uses the U.S. Navy Fitness formula for estimating body fat percentage:
- For men: 495 / (1.0324 – 0.19077 * log10(waist – neck) + 0.15456 * log10(height)) – 450
- For women: 495 / (1.29579 – 0.35004 * log10(waist + hip – neck) + 0.22100 * log10(height)) – 450
The lean body mass is calculated by multiplying the weight by the percentage of lean tissue (100% – body fat percentage).
The basal metabolic rate (BMR) is calculated using the Harris-Benedict equation:
- For men: 88.362 + (13.397 * weight) + (4.799 * height) – (5.677 * age)
- For women: 447.593 + (9.247 * weight) + (3.098 * height) – (4.330 * age)
Limitations
This calculator provides an estimation based on standard formulas and statistical averages. Individual results may vary depending on numerous factors such as genetics, body composition, and overall health.
