TheComposition Matrix
Weight is a blunt instrument; body fat percentage is a precision tool. Knowing your body fat allows you to differentiate between weight loss (which can include muscle) and fat loss (the ultimate goal for health and aesthetics). Our engine uses anthropometric data to estimate your composition with clinical-grade accuracy.
AnthropometricLogic
The US Navy Method
Our calculator implements the US Navy Body Fat formula, which utilizes circumference measurements (neck, waist, and hips) as a proxy for total adipose volume. This method is statistically accurate within 3-4% for the general population and avoids the 'Athletic Bias' of BMI.
