About Body Fat Percentage
Body fat percentage is a more meaningful health indicator than BMI because it distinguishes between fat and lean mass. The US Navy method uses circumference measurements and was developed for military fitness assessments.
| Category | Men | Women |

For accuracy, take measurements in the morning before eating, with a flexible tape measure held snug but not compressing the skin. Repeat three times and average.
