What Is Body Fat Percentage?
Body fat percentage represents how much of your total body weight consists of fat. Unlike BMI, it focuses on body composition rather than just height and weight.
How the Body Fat Estimator Works
This calculator is based on the U.S. Navy body fat formula, which estimates body fat using circumference measurements such as waist, neck, and hips (for females). It provides a practical estimate without requiring specialized equipment.
Why Measurements Matter
- Waist size reflects abdominal fat distribution
- Neck circumference helps adjust for upper-body mass
- Hip measurements improve accuracy for females
Healthy Body Fat Ranges
Healthy body fat percentages vary by sex and age. Athletes typically have lower body fat levels, while average healthy adults fall within moderate ranges. Extremely low or high values may indicate health risks.
