How to use:
- • The US Navy method uses circumference measurements — more accurate than BMI-based
- • Measure waist at the navel level; neck below the larynx; hips at the widest point (females)
- • Use a flexible tape measure and measure 3 times, taking the average
- • The BMI method only needs weight and height but is less precise
- • For medical-grade results, use DEXA scan or hydrostatic weighing
