About This Result
The US Navy Method: This estimation is based on the 1984 US Navy Body Fat Formula, which uses anthropometric measurements to calculate body density. While not as precise as a DEXA scan, it provides a reliable, accessible baseline for tracking body composition changes over time.

Focus on the 1% wins daily. Use this data as a compass, not a verdict. Progress is a journey of habits, not just numbers.
