Understanding Your Body Fat Percentage
Your body fat percentage is the proportion of fat your body has compared to its total mass. It is a more accurate indicator of health and fitness than Body Mass Index (BMI), which can't distinguish between muscle and fat. Monitoring your body fat can help you track progress in a fitness program and assess your health risks.
How This Calculator Works: The U.S. Navy Method
This calculator uses the "U.S. Navy method", also known as the YMCA method. It's a popular and scientifically validated approach that estimates body fat percentage using circumference measurements. It requires only a tape measure and provides a good estimate for most people.
- For Men: The calculation uses height, neck, and waist measurements.
- For Women: The calculation uses height, neck, waist, and hip measurements.
