About the Navy Body Fat Calculator

However, it doesn’t accurately assess as well as calculate their body fat contents and so although it estimates the body fat, a person can be making use of this tool to trace out their health development within the years.

The method was originally developed by the US Navy for quick body fat assessment that did not necessitate expensive lab equipment. Now, it's one of the most recognized online body fat methods.

Factors That Affect Navy Body Fat Results

Measurement Accuracy

Even a slight inaccuracy when taking body measurements for waist, neck, and hips can make a big difference in body fat assessment. Take your measurements using a soft and flexible tape measure as well as ensuring that measurements are in the designated locations, especially when using a body fat calculator for the first time.

Body Position

Body posture. The most reliable readings are obtained when you stand with your body and muscles completely at ease. You cannot rely on either tensed stomach muscles or holding your breath.

Tape Placement

All measurements should always be taken around the predetermined anatomical landmarks. Even the smallest adjustment in placement of the measuring tape will change the resulting percent.

Gender

Body fat distribution varies normally between men and women; accordingly, the Navy uses distinct equations for each gender.

Height Measurement

Incorrect measurements of height have a real impact. Use a hard wall and remove your shoes when measured.

Recent Meals and Hydration

A big meal, too many beverages and even bloating could temporarily boost measurements around your waist and result in a small shift in your estimated amount of body fat.

Body Shape Differences

If you have body shape anomalies, a lot of muscle, or a peculiar spread of body fat, you will get readings that vary from laboratory procedures.

Consistency Over Time

2. Check similar conditions “Every time check conditions, if it is in the morning before breakfast because the natural differences at different times in the day are minimal to make such a comparison in vain “
