Understanding Body Fat
Learn what body fat percentage means and why it matters for your overall health.
What is Body Fat Percentage?
Body fat percentage is the proportion of fat mass to total body weight. It provides a better picture of body composition than weight alone.
Why It Matters
Body fat levels affect hormones, metabolism, and risk for diseases. Too much or too little can both be problematic for health.
Healthy Ranges
Essential fat: 2-5% (men), 10-13% (women). Athletes: 6-13% (men), 14-20% (women). Fitness: 14-17% (men), 21-24% (women).
Measurement Methods
Methods include skinfold calipers, bioelectrical impedance, DEXA scans, and circumference measurements. Each has different accuracy levels.
Better Than BMI
Unlike BMI, body fat percentage distinguishes between muscle and fat mass, making it more accurate for athletes and fit individuals.
Tracking Progress
Measure under consistent conditions (time of day, hydration). Focus on trends over time rather than single measurements.
