How We Calculate Your Body Fat
Transparency in our calculations builds trust. Here's exactly how our body fat calculator works.
The Formula
U.S. Navy Method
Uses circumference measurements (neck, waist, and hips for women) to estimate body fat percentage.
Why We Use This Method
We chose the U.S. Navy Method method because it's widely recognized in the scientific community for its accuracy and reliability. Multiple validation studies have confirmed its effectiveness across different populations.
Our implementation follows the exact specifications from peer-reviewed research, ensuring you get results that align with established nutritional science.
Limitations
While this calculator provides a good estimate, individual results may vary based on factors like:
- Metabolic differences between individuals
- Body composition (muscle vs fat ratio)
- Medical conditions that affect metabolism
- Accuracy of the input measurements
For personalized recommendations, we recommend consulting with a registered dietitian or healthcare provider.
