The Navy Body Fat Formula

Developed by the U.S. Navy, this method relies on a regression equation that correlates body fat percentage with weight and height. While it's important to note that this is an estimation and may not be as accurate as more advanced techniques, it provides a quick and convenient way to monitor changes in body composition over time.

The Regression Equation

The Body Fat Navy Hodgdon Weight-Height Regression Method employs the following regression equation:

Why Another formula?

It is important to understand that methods for estimating Body Fat can change over time. Further, as described in the below table, accuracy and easy of measurement are often factors to consider. Having said that, there is an assumption on our side based on having read the original research papers that the body fat accuracy required was slightly relaxed thus making this simple weight and height formula a powerful and validated option.

The directive left the task of developing the most appropriate methodology for body fat determination to the individual services. The directive did require that fat measurement techniques must have a correlation coefficient of 0.75 or better with percent fat from underwater weighing. This coefficient has since been increased to 0.85.
