What is Body Fat Percentage?
Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It includes both essential fat and storage fat.

Measurement Methods
Navy Method: Uses circumference measurements to estimate body fat. Considered reasonably accurate for most people.
BMI Method: Uses height and weight to estimate body fat. Less accurate but requires no measurements.
For clinical accuracy, consider DEXA scans, hydrostatic weighing, or BodPod tests.
