If one number is far off from the others, either you have a body part that you may know is not in symmetry with others (like maybe big calves compared to thighs/hips), ect - or it'll auto-correct as you lose fat. That will minimize known expected water weight fluctuations. So always do these and weight the morning after rest day, eating normal sodium levels, not sore from last workout. With both methods, you can present a body that is different than last time in water weight and throw it off. If you have average body symmetry (like if J Lo and you know you have big booty - formula's will be off), a mix of them can yield about 5% accuracy, or 3% both directions or 6% you might say. Potential accuracy of the measurement methods. Potential accuracy of caliper method from study.

Use the same test and input the data required and you should see a trend over time.īasically with all testing, just be consistent in your method and HOW to test and you will be more accurate. For instance, if bodyfat measures at 27% this month and next month it measures at 26.5%, then you have seen a reduction regardless of whether you are truly that percentage. Body fat- Under the same conditions, you should be able to see a change when using the same method to evaluate progress. Measurements- Have the same person take measurements for you, wearing no baggy clothing, and use the same exact sites to measure every single timeģ. Weight- Use the same scale, same time of day, same amount of clothingĢ. Whatever method you choose, use the same exact method under the same exact conditions every single time you test it.ġ. I had a physiology teacher explain to us that we will never know our true bodyfat until we are dead, can have all of the tissue separated and water sucked out of us. Monitor weight weekly, measurements biweekly or monthly along with bodyfat testing (if you choose to use it)Īs far as accuracy goes, they all have about a 3-5 percent margin of error in almost all of the testing methods outside of bodypod.and that even has a margin of error of 1 - 2.7!

Your Body Mass Index (BMI) can be used as a (very) rough rough indicator of body fat percentage.

For most people, the Navy method is accurate to within 3%.īody Fat Percentage = Body Fat Percentage = 86.010 x log10(Waist - Neck) - 70.041 x log10(Height) + 36.76īody Fat Percentage = 163.205 x log10(Waist + Hip - Neck) - 97.684 x log10(Height) - 78.387 These measurements are combined with your gender and height to estimate body fat percent. Measurements are taken at the narrowest point for waist and neck for males, and waist, neck and hips for females. The Navy body fat calculator uses body circumference measurements along with height to estimate body fat percentage. Women require five measurements: Body weight, Wrist Circumference, Waist Circumference, Hip Circumference, and Forearm Circumference.Įxample: A woman weighs 125 with a wrist measurement of 6, a waist measurement of 24, a hip measurement of 38, and a forearm measurement of 9.5: Men require two measurements: Bodyweight and Waist Circumference (measured at the belly button).Įxample: I weigh 185 and I have a 33 inch waist.
