    Default Which Body Fat calculator is accurate?

    I took this one using the tape measure method.

    http://www.linear-software.com/online.html

    I got 31% body fat. Previously I got 32%.

    Then I took this one:

    http://www.healthcentral.com/cholest...3.html?ic=4002

    and I got 18% bf!!!

    Then I took this one:

    http://www.csgnetwork.com/bodyfatcalc.html

    and I got 38% bf

    Then I took this one:

    http://www.he.net/cgi-bin/suid/~zone/prothd1

    and got 26%

    (BTW, where is my waist supposed to be? Is it the narrowest part of my
    body (which is just a bit below my breasts? (27") or is it where my
    belly button is (31")? I'm assuming it's where my belly button is,
    except for when they say to measure the narrowest part.

    I took this one:

    http://www.healthstatus.com/calculate/bfb

    and got 25.53% based on the US Navy body fat formula
    and 38.13% based on the YMCA formula

    In this calculator they asked for my narrowest point and measurement at
    navel.

    I'm going to be not so optimistic and assume my body fat is 38% :-(

    I know for sure I have a lot of body fat. Even my knees are fat.

    I'm obese at 112 lbs. I have a normal BMI yet I'm obese according to my
    body fat.

    You are right. The YMCA calculation is a little high. It has me at 17.5
    % body fat, but I am actually at 11% body fat, if the reistance testing
    is any more accurate. It appears that the only really reliable test is
    the underwater test, though, and nobody around here does those. Maybe
    I'll go in the business and charge about $50 per test. dkw

    This one says I'm 21%.... much too low.

    This one says 14%. That's WAY TOO low for me!

    This one says 23%. Probably within 1-2% of where I'm at, and with the least
    amount of measurements. But of course, it will depend on where you tend to
    carry most of your fat...

    The narrowest point is generally considered the natural waist, and is
    usually above the bellybutton just a bit. It is "supposed" to be 10"
    smaller than your hips, for the best proportions.

    That's stupid. These tests are soooo varied and subjective, why would you
    take the test with the absolute worst results and go by that??? The thing
    for you to do is go to your local gym and request a 7 site caliper test.
    Quit trying to figure your bodyfat from an internet calculator. They aren't
    accurate for everyone. Perhaps after you find out where you really are, you
    can go back through the different sites and figure out which one is closest
    to you. But until then, you are merely stabbing in the dark.

    I wish you could post pics. It is completely hard to believe that you are
    fat at 112.

    The man with one watch knows what time it is. The man with
    two watches is never sure.

    The moral of the story - What you are doing is going out of your
    way to confuse yourself. As you can see it's working out just
    fine that way.

    The point of body fat percentages is the *change* over time,
    not the fact that each method is different from the next.

    If you have two scales and they read 10 pounds different,
    did you lose 10 pounds by stepping on one and then one the
    other? Nope! Did you gain 10 ten pounds by switching back
    to the first one? Nope!

    Pick a method and try it again next month. THAT has meaning.
    What you're doing now doesn't have meaning.
