    If you can get it/afford it, the immersion test for body fat % is the most accurate method out there. The next best is callipers, followed by the hand-held gizmos, then finally the scale that measures through the feet. My scale bf% goes up when I go down in weight. Figure that one out!

    Tape measure?

    The formulas for figuring BF% from a tape measure aren't particularly accurate in an ultimate sense, however changes in a relative sense are extremely accurate. While the formula telling you you are at 15% might be a bit off, if you lost 2.5 %, chances are that is quite accurate and on par with the best of the best other methods.

    The Navy method is pretty accurate, and you just need a tape measure... here is a website to show you what you need

    I use the Navy method as well. I compared it to caliper measurements and the results were very similar. I also have a bio impedance scale that is mostly useless, giving me a bf of 17% on a good day.

    If the reading goes down and you measure consistently, then isn't that ok?

    Unless there is a health issue and you really need the result for health reasons.

    There are 2 main body fats, one is good old fashioned fat under your skin that we can all see easily when we look at our muffin tops bulging over our jeans.....

    Another is known as VISCERAL fat. This is where fat cannot be seen, it wraps itself around your organs, and can cause serious health problems. If you diet and exercise you should reduce this visceral fat... It is usually visceral if you think you are thin but have % which seems high... YOURS is not high.

    TOFI Thin Outside Fat Inside.

    I am on intermittent fasting diet and that does seem to reduce visceral and normal fat as well as targetting very many health issues.

    Look up 5:2 intermittent fasting - if you are intrigued!

    The Navy formula tends to be low for me.

    The modified YMCA formula seems to give a more accurate result for me. The regular YMCA formula seems to be a middle ground of the two.

    (I'd love to be at the 11% the Navy formula says I'm at, but chances are the 13% I get from the mYMCA formula is closer to reality).

    Either way, the difference is pretty much just a matter of zero point, both change at almost exactly the same rate.

    Waste of time and money..... all you need is to know you're not losing strength while dieting (not much anyhow).... know your losing weight.. and watch the mirror.... If you look in the mirror and you think you need to lose more weight, and then a scan tells you you're the percentage you wanted to be, what are you going to do?

    I've sort of been thing the same thing about numbers lately. As long as there is fat showing or hanging, or something jiggles, I'm not quite there. I can see where athletes need this information for speed or things like that, though. I am recording how I obtained my BF% and will use the same online tool the next time I check it, just as one measure of progress. My clothes are probably the best indicator at the moment, though. : )

    When I compare my body to other's online with similar builds, the fat2fit calculator seems to be more in line than the NAVY calculator, if anyone wants to try it out. http://www.fat2fitradio.com/tools/bf/ I like all their tools. You can enter your goal BF, current weight and height, and they will calculate what your body weight will likely need to be to get to your goal BF. Seems to me that lean muscle mass may affect this some, but I imagine it's close.

    I'm currently using the fat2fitradio.com body fat calculator (the Military one), but I think I'm going to plug my numbers into the Navy one this afternoon when I get home. I like that it asks for so many different measurements. Maybe I'll start using that one.

    I don't really care what the actual number is right now. As long as the number goes DOWN, I'm a happy camper.

    If you find it hard to get the measuring tape straight (especially with hip and waist measurements), invest in a Myotape. They're not expensive, and SO easy to use.

    The statistics I've seen rate DEXA as the most accurate

    Your BF% could go up as you lose weight if you also lose muscle. It could be poor measurement, but if it's actually increasing you should probably tweak your diet and exercise plan.
