About the Navy method

The US Navy body fat formula uses simple circumference measurements to estimate body fat percentage. While not as precise as DEXA scanning or hydrostatic weighing, it is convenient and reasonably accurate for most people.

This is an estimate only. Body fat measurements can vary based on measurement technique and individual body proportions. For clinical accuracy, consult a healthcare provider.
