Anyone Had a DEXA Body Composition Scan Before?

I'm considering getting a body composition scan which supposedly accurately tells you your fat/muscle/bone composition of your body. Not exceedingly expensive. Sample report. Has anyone had one before? Was it useful? I'm just curious :)

Update: results

My (unprofessional) analysis is:
- 11.4% body fat including my head, 10.7% excluding head.
- Low visceral fat 290g (R1 region), < 900g is supposed to be low-risk.
- Bone mineral density normal, but slightly below average for my age.
- I've got a fat right leg (13.2% fat right vs 11.8% fat left) and a fat bum 13.8% :)

So, low body fat but not a particularly huge amount of muscle. Not surprising given that I can see all the veins popping out of my arms. I've still got a little bit of fat on my lower back and stomach.

I've recently started doing weights to build some muscle on my chest and improve my bone mineral density. Lots of eggs and dairy …. mmmmm.

In 4 months time I'll do another scan to find out how well I've been doing.

My blood pressure is low, typically <= 100/60 sitting around at the computer.

My set of ALDI fat scales are grossly inaccurate, saying I've got over 20% body fat (I suppose it measures the fat in my legs).

Total Chol           3.7 mmol/L   (3.9-5.5)
HDL-C                1.13 mmol/L  (0.9-1.5)
LDL-C                2.3 mmol/L   (0-4.0)
Trig                 0.6 mmol/L   (0.3-2.2)
Fasting blood gluc   4.8 mmol/L   (0.6-2.0)

Sep 2014

Total Chol           3.3 mmol/L   (3.6-6.9)
Trig                 0.8 mmol/L   (0.3-2.2)
Fasting blood gluc   4.7 mmol/L   (3.0-6.0)

This was for moderate carbs, high fibre (50g+/day) + adequate protein to preserve muscle. No refined carbs (pasta, bread, wheat, flour), no added sugar, no added salt, no frutcose besides fruit. Nuts + berries + legumes + fish + chicken + dairy + oat bran + eggs + veggies + a couple of pieces of fruit per day (100-150g carbs/day). I dropped heaps of weight very easily (hopefully mostly fat).

Total Chol           4.7 mmol/L   (3.6-6.9)
Trig                 0.5 mmol/L   (0.3-2.2)
Fasting blood gluc   4.3 mmol/L   (3.0-6.0)
Testosterone level   45.2 mmol/L  (11.0-40.0)

This was for high fat + moderate carbs (100-150g) + adequate protein (100-120g). I was worried that my total cholesterol was very low (which is associated with a greater risk in terms of overall mortality) so I added 50g of coconut oil + 50g of olive oil each day to my diet. The coconut oil (90% saturated fat) has bumped up both my HDL-C and LDL-C considerably (no individual measurements unfortunately).

  • Never mind! Answered my own question

  • Not exceedingly expensive.

    I'm curious - how much were you quoted? Could it potentially be covered by Medicare (for certain health investigations, say, osteoporosis / bone density? - if anyone happens to know?)

    hmm. Subbed. :)

      it is might be covered by medicare if you are referred by a gp for possible osteoporosis (i'm not sure).

      i'm more interested in the body composition side and tracking it over time, say for body building. no referral is needed.

      For the place close to me, the fees are here. $88 for initial scan and $66 for subsequent scans. or the 4 pre-paid scans for $200.

      • Cool bananas.

        (bone density is still an element of body composition - quite an interesting one to know, too, I'd say.. though, I dunno if that would change much for fit adult blokes? its more an issue for women and may be a changing factor if a female is working on improving fitness, ie. bone density may improve if it starts off poor, with increased fitness training / weight bearing exercise… but anyway!)

        Not a bad price either. I'd do it. Stats are awesome if you're into that side of things.

    I've had 4. It depends on what you are getting it for but I think they are extremely worth it. Just remember that you should go to the same machine and same operator for future scans.

    Happy to answer any questions

    can't you get scales that can do all that jazz for like $100-$200

    • +1

      Bioimpedence scales are wildy inaccurate and frankly just plain crap. DEXA tells you how much Fat, Lean Mass, Skeleton weight, visceral fat and a true weight reading.

      It literally breaks you down into Left arm, right arm, head etc etc etc and tells you exactly how much fat and lean mass to the exact gram.

      • +1

        Actually, usually to the 1000th of a gram :)

      That's how those bathroom scales work. I wouldn't waste a dollar on them, personally.

      DEXA is far more comprehensive and to the T.

      Also known as DXA: http://en.wikipedia.org/wiki/Dual-energy_X-ray_absorptiometr…

    Had 1. Wanted to find out bone density and body fat percentages. Planning to go in another 6 months to find out whether exercise/diet is moving those numbers in the right direction.
    I got a little deduction in fees via health fund.

  • I've had maybe 8-10.

    Have it done every 6 months so I can track my fitness in terms of fat lost and also muscle mass gained.

    If you're not that into fitness then at least having one will be good for reference.

    If you're into fitness and hard stats then regularly having one is good.

    thanks all. i'll post my report for all to giggle at when i get it done in a couple of days.

  • +1

    i did my test today. results are in the post.

    • Looking forward to the results. Thanks for sharing :)

      (derp, now I see you've already added them to the first post lol.. I'm a bit late to the thread)

  • really wish i had had one of these done before I started on my health kick a couple years ago and present time. Sounds great.

  • Mattgal, now we know your BF% results from a proper scan, would you mind doing something to indulge my curiosity please? lol

    If you've got a tape measure handy, and plug in your measurements for the Navy Tape Measure Method here… what BF% does it calculate for you? Just wondering how close to the DXA scan results it is. See, I have a tape measure at home, but no DXA scanner ;)

    My set of ALDI fat scales are grossly inaccurate, saying I've got over 20% body fat

    +1 for comparing those results and sharing, too. Interesting to have solid stats to compare everything to now!

    • +1

      14.9% for the tape measure method. a better indictator than those scales :)

      • Thanks!
