Body Fat (Fitness)
> 25.0 Obese
< 6.0 Essential fat
Understanding one's body composition is a key aspect of health and fitness. The Body Fat Navy Hodgdon Weight-Height Regression Method provides a practical approach to estimating body fat percentage using only weight and height. This method, rooted in simplicity, offers an accessible way for individuals to gauge their body fat levels without the need for advanced tools. In this article, we will explore the principles behind this method and guide you through the process of calculating your body fat percentage.
The Body Fat Navy Hodgdon Weight-Height Regression Method
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.
|Based On||Weight||Tape Measure||Skinfold|
|Measurement Complexity||Very Easy||Easy||Difficult|
|Best Suited For||Non-Active Person||Active Enthusiast||Athlete|
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.

The Body Fat Navy Hodgdon Weight-Height Regression Method offers a straightforward means of estimating body fat percentage using only weight and height. While it may not be as precise as some advanced methods, it serves as a convenient tool for individuals seeking a quick assessment of their body composition. Regularly monitoring changes in body fat percentage can be a valuable part of a comprehensive approach to health and fitness. Remember, for more accurate assessments, consider consulting with healthcare professionals or utilizing advanced measurement techniques.
