Body Fat Calculator
Estimate your body fat percentage using the US Navy method
Body fat is the percentage of your body mass that is fat tissue. Essential for various bodily functions, it also impacts overall health.
- Provides energy storage
- Insulates the body
- Protects organs
- Supports hormone production
However, excess body fat can lead to health problems.
To use the US Navy method, you'll need:
- Weight: Use a calibrated scale, preferably in the morning
- Waist Circumference: Measure at navel level, while standing and after normal exhalation
- Neck Circumference: Measure around the neck, just below the Adam's apple
- Hip Circumference (Women): Measure around the widest part of your hips, ensuring the tape is horizontal
Take measurements in the morning, before eating, for most consistent results.
Body fat percentages are interpreted as follows:
- Essential Fat: 2-5% (Men), 10-13% (Women)
- Athletes: 6-13% (Men), 14-20% (Women)
- Fitness: 14-17% (Men), 21-24% (Women)
- Acceptable: 18-24% (Men), 25-31% (Women)
- Obese: 25%+(Men), 32%+(Women)
These ranges are general guidelines; consult a healthcare professional for personalized advice.
