How to Measure Body Fat |

When I wrote about ways to measure your body, I got a question about how one goes about measuring body fat. I wrote to the person who left the comment, but it makes sense to cover the topic for everyone’s benefit.
One of the best ways to measure fat is through hydrostatic weighing. In short you dunk yourself in a tank of water and some smart people perform some calculations. I really don’t know too much of the science of it, except that it’s accurate and it’s more effort than a Lazy Man like me wants to go through. Since this costs money every time you want to do it, this article is a good start.
Another option is the caliper test. This is a device that you use to pinch your fat and measure how much you can grab. It can take a bit of practice to get good at performing a accurate test on yourself. If you want to invest the time why not try these
I have a Tanita Body Fat Scale
I also have a Omron Handheld Fat Loss Monitor
It might be overkill to have both. I figure one measures the fat stores in the lower part of my body. The other does the upper part of your body. I average the two to come up with what I feel must be close to accurate measurement. Even if it’s not accurate, all that really matters to me is the relative numbers and week to week improvement.

Wow, freaky deja vu. I’ve been going through a similar process regarding BMI and, unfortunately for me, my Tanita isn’t cutting it with my current weight. How is the Omron? I’m thinking about getting one.

I find it interesting that you have two BIA devices that give you different results. I’m curious to know if the algorithms are different, or if has to do with the way the pulses are conducted (ie, through hands vs feet). I imagine the Omron is less because you are male and would have more FFM/TBW in your upper body…

You are 100% right about the impedance scales (TAnita & Omron) measuring only part of your body.
I use both with clients, and always see a difference between the measurements.
So one day, I called up both companies and after over an hour on the phone, I got one of the Omron techs to admit that the current travels from one hand through the torso and out the other hand.
No lower body fat is measured.
I can only assume the same is true for the Tanita scale (they wouldn’t admit to squat). But the Omron guy said that since it is the same technology, he assumes that the current would travel up one leg, through the pelvis & lower torso, and back out the other leg.
On another note, I really enjoyed your blog and I would love to exchange blogroll links.
