Yes, for most purposes. BMI is a population-level tool that doesn't account for muscle mass, age, or fat distribution. A muscular athlete may have an 'overweight' BMI with perfectly healthy body fat. Body fat percentage is more clinically meaningful.

How accurate is the Navy method?

The US Navy method has an error margin of ±3–4% compared to DEXA (gold standard). It's more accurate than BMI but less precise than underwater weighing, DEXA scanning, or air displacement plethysmography. It's the best method available without special equipment.

How do I measure correctly?

Waist: measure at the narrowest point, typically 1 inch above the navel, after exhaling. Neck: measure just below the larynx. Hip (women only): measure at the widest point around the buttocks. Use a flexible tape measure and measure in the morning for consistency.
