Dexa Scan

Today I had my free dexa scan. Body composition test which is 99% accurate on measuring your body fat. As I am on my bulk cycle I was thinking maybe I should of cut a bit to get a lower number :D. I bulk fairly lean. My estimate I had in my mind was high 10 low 11%. My calipers worked out to about 9.4% which is mainly for sub region fat. So with this in mind I went in to get my base line for my bulk and a goal for when I cut. The dexa machine is pretty funky, just a table and a little arm that comes over you and the table moves forward, back, up and down. The Arm moves as well. It makes 3 passes of your body with different angles. Makes some funky tunes and beeps and it’s done within 3 minutes. I wasn’t expecting a fantastic result as i am putting weight on. I was wondering if my measuring and guestimations are on the mark. So lets get to the results (Dual-energy X-ray absorptiometry) DXA scans are used primarily to evaluate bone mineral density. DXA scans can also be used to measure total body composition and fat content with a high degree of accuracy comparable to hydrostatic weighing with a few important caveats.


BMC is Bone mineral content, basically the weight of you bones. My skeleton is 2.6kg 🙂

FAT MASS – How much fat you have

LEAN MASS – Lean muscle weight Lean+bmc – lean weight + skeleton

Total mass – How much you weigh

%fat – body fat percentage . Measured in two areas , whole body and r1 sub abdominal region. Everyone’s head contains at least 20% fat so you need to take that off the total and use the subtotal for your fat amount. As expected i am bang on 11% which is what I guestimated just from looking. I am holding weight in my hips and thighs only at the moment.


Colored skeleton is the fat distribution. Yellow is FAT orange and red are lean mass and blue is bone. I haven’t got too much fat as you can see. the r1 region is marked on the grey skeleton. People are supposed to have under 900gs of fat there. I have 363g not bad … Would be lower when i get back to 7% i hope :). As from the report you can see BMI is total bullshit. They need to get rid of it.


The 3rd page is bone density. The scale is -1.0 to +1.0 so my -0.6 is a pretty good result. So yes , something interesting. Gives me an idea what I need to work on and how my guesses are pretty good when it comes to estimating someone’s fat percentage.
