Vanliga frågor
What is a normal body fat percentage? ▾
For men, 10–20% is fit, 20–25% is normal. For women: 18–28% fit, 25–35% normal. Athletes often have 6–13% (men) or 14–20% (women).
How accurate is the BMI-based method? ▾
The Deurenberg formula has an accuracy of ±3–5 percentage points. For more precise measurement, DEXA scan, hydrodensitometry or BIA scales are recommended.
Why is body fat percentage more important than weight? ▾
Two people with the same weight can have very different body compositions. Muscle weighs more than fat – someone who exercises may be heavier but have less body fat.
