About Body Fat Calculation

The US Navy Method uses body circumference measurements to estimate body fat percentage. It was developed for military fitness assessments and is reasonably accurate for most people.

The BMI Method (Deurenberg equation) estimates body fat from BMI, age, and gender. It is less accurate than direct measurement methods but useful when only basic measurements are available.

Both methods provide estimates. For the most accurate measurement, use DEXA scans or hydrostatic weighing at a health facility.
