Understanding the US Navy Body Fat Method
While the Body Mass Index (BMI) is useful for general populations, it fails to account for muscle mass. The US Navy Body Fat Calculator solves this by using simple tape measurements to estimate your actual body composition. It relies on the circumference of specific body parts to determine how much of your weight is lean tissue versus fat mass.
How to Measure Accurately
- Height: Stand straight without shoes.
- Neck: Measure just below the larynx (Adam's apple), keeping the tape flat and parallel to the floor.
- Waist:
- For Men: Measure horizontally at the navel level.
- For Women: Measure horizontally at the narrowest point of the abdomen.
- Hips (Women Only): Measure at the widest point of the hips and buttocks.
Lean Mass vs. Fat Mass
Your Lean Mass is everything in your body that isn't fat: muscles, bones, organs, and water. By tracking your body fat percentage alongside your weight, you can ensure that your diet and exercise routines are burning fat rather than degrading healthy muscle tissue.
