Q1: What is body fat percentage and why does it matter?
Body fat percentage is the proportion of your total body weight that is fat tissue. Unlike BMI, it distinguishes between fat and muscle. Healthy ranges vary by gender and age, but generally: Men 10-20%, Women 18-28%. Lower isn't always better - essential fat is necessary for health.
Q2: How is body fat percentage estimated?
This calculator uses the Deurenberg formula, which estimates body fat based on BMI, age, and gender. It's a quick estimate but less accurate than methods like DEXA scans, BodPod, or calipers. For precise measurements, use professional body composition analysis.
Q3: What are healthy body fat percentage ranges?
Healthy ranges: Men: Essential 2-5%, Athletes 6-13%, Fitness 14-17%, Average 18-24%, Obese 25%+. Women: Essential 10-13%, Athletes 14-20%, Fitness 21-24%, Average 25-31%, Obese 32%+. Age and individual factors affect these ranges.
Q4: Why might my body fat percentage seem inaccurate?
BMI-based estimates have limitations. They don't account for muscle mass, bone density, or fat distribution. Athletes with high muscle mass may get inaccurate readings. For accurate measurement, use DEXA, BodPod, hydrostatic weighing, or professional caliper measurements.
Q5: How can I reduce my body fat percentage?
Reduce body fat through: calorie deficit (eat less than you burn), strength training (preserve/build muscle), adequate protein intake, regular cardio, sufficient sleep, and stress management. Focus on fat loss, not just weight loss, to improve body composition.
Q6: Is low body fat always better?
No, extremely low body fat can be unhealthy. Essential fat is needed for hormone production, organ protection, and normal bodily functions. Very low body fat (men <5%, women <10%) can cause health issues. Aim for a healthy range, not the lowest possible.
