The InBody 570 Body Composition Analyzer measures body fat using the same basic principle as a home bathroom scale: electrical conductivity. However, this machine uses much more sophisticated technology.

So today I set out in the pouring rain to meet up with Ayda Ersoy at BASE Fitness in North Vancouver. Ayda has one of the very few InBody units in the Metro Vancouver region, and she’s happy to help people get their results. Once in a while she’ll even travel it around to different gyms to make it more accessible for a wider range of people!

The scan set me back $60, which was half the price that I paid for a DEXA scan. But more importantly, this type of scan is very safe, so it’s fine to use it as frequently as you can acess a machine to do so. That’s unlike the DEXA scan, where you really want to minimize your X-ray exposure. But enough chat, let’s jump right to the results (PDF).

InBody results

The result: 21.3 percent body fat! That’s right in between my results from DEXA (29.4%) and the Fitbit Aria2 (17.3%). Apparently the InBody 570 is supposed to calibrated and scientifically evaluated to be 98% accurate with DEXA, but apparently my body is the exception to that rule.

So far, this experiment seems to be proving my hypothesis that body fat measurement is closer to tarot card reading than a real solid science.

For anyone else in the Metro Vancouver area who wants to try an InBody machine, Ayda mentioned that there are a couple others around.

Yes, there’s a few places — they have one at Capilano University, but they don’t accept people from outside the university; there’s one at Copeman Clinic downtown, but I know they’re really expensive too, so you should check the price before going; and there was one in Richmond, but I can’t remember the name and I couldn’t find it now either, you can try looking if you like.
