How These Estimates Work

If you enter body fat percentage directly, the estimator uses that as the main anchor for fat mass, fat-free mass, water, muscle, protein, and bone estimates. If you do not enter body fat percentage, the tool will estimate it from either your optional circumference measurements or your main anthropometric inputs. Visceral and subcutaneous fat values are modeled estimates, not direct scans.
