Question 1

Is the U.S. Navy Method reliable?

Accepted Answer

Yes. Scientific studies show that the U.S. Navy estimation has a standard deviation of only 3% to 4% compared to a DEXA Scan, making it much more reliable and stable than most household bioimpedance scales.

Question 2

How do I measure body fat at home?

Accepted Answer

Use a flexible tape measure. For men, measure the neck and waist (at the belly button). For women, measure the neck, waist (narrowest part), and hips (widest area).

Question 3

What is a healthy body fat percentage?

Accepted Answer

For men, the ideal healthy range is between 14% and 24%. For women, due to hormonal and reproductive needs, the perfectly healthy range is between 21% and 31%.

Question 4

BMI or body fat percentage?

Accepted Answer

Body fat percentage is superior to BMI for evaluating actual physical health. BMI is only a basic mathematical ratio of weight/height, while body fat measures actual tissue composition.

Question 5

Do women naturally have higher body fat?

Accepted Answer

Yes. Women biologically have more essential adipose tissue due to evolutionary factors, including pregnancy, lactation, and the production of female hormones like estrogen.

Question 6

Can I use it without calipers?

Accepted Answer

Yes! Our calculator was specifically developed not to require calipers, using only simple body circumference measurements with a standard tape measure.
