How Body Fat Calculation Works - Medical Methodology

Our Body Fat Calculation System uses US Navy-verified medical formulas to provide accurate health assessments and body composition insights. Here's the complete technical methodology:

Core Navy Method Formula: Uses circumference measurements (neck, waist, and for women, hips) along with height to estimate body fat percentage. This method was developed through extensive US Navy research.

Male Formula: Body Fat % = 495 / (1.0324 - 0.19077 * log10(waist - neck) + 0.15456 * log10(height)) - 450

Female Formula: Body Fat % = 495 / (1.29579 - 0.35004 * log10(waist + hips - neck) + 0.22100 * log10(height)) - 450

Body Fat Categories: Essential, Athletic, Fitness, Average, Obese - each with specific health implications and recommendations.

Lean Body Mass Calculation: LBM = Total Weight × (1 - Body Fat % / 100) - provides insight into muscle mass and metabolic health.

AI Accuracy Enhancement: Our algorithms incorporate medical research data across different populations and health conditions to provide context-aware health recommendations.
