Understanding Body Fat

Why Body Fat Matters

Body fat percentage is a better indicator of health than weight alone. It shows your body composition and helps assess disease risk and fitness level.

Measurement Accuracy

Navy method is most accurate for general use. Skinfold requires proper technique. DEXA scans provide the gold standard but aren't accessible to everyone.

Essential vs Storage Fat

Essential fat (men: 2-5%, women: 10-13%) is required for basic functions. Storage fat provides energy and insulation. Balance is key to health.

Improving Body Composition

Combine strength training with cardio and proper nutrition. Focus on building muscle while reducing fat for optimal body composition.
