Frequently Asked Questions
What is a healthy body fat percentage?▾
For men, 10–20% is typical for fit individuals, with 6–13% for athletes. For women, 18–28% is typical, with 14–20% for athletes. Extremely low body fat can be unhealthy.
How accurate is the Navy method?▾
The Navy method is accurate to within about 3% for most people. It uses simple measurements (neck, waist, and hip for women) and is more reliable than BMI for body composition.
What is the difference between essential and storage fat?▾
Essential fat is needed for normal body function — about 2–5% for men and 10–13% for women. Storage fat accumulates in adipose tissue and varies much more between individuals.
Is body fat percentage better than BMI?▾
Body fat percentage is generally more meaningful because BMI doesn't distinguish fat from muscle. A muscular person can have a high BMI but a healthy body fat percentage.
