Dexa Scan – Review & Results

3 Aug

Yesterday I went to get a dexa scan and I have to say it was honestly one of the most interesting things I have ever done in my life!

What is a Dexa Scan?

Body Composition Australia uses the worlds most advanced scanning technology from Hologic, USA.  Dual energy x-ray absorptiometry (DEXA), assesses total body bone mineral density and highly accurate measures of the body’s soft tissue composition (muscle mass and fat mass).  By measuring your body’s muscle mass, fat mass, and bone mineral density, Body Composition Australia can determine your total body fat percentage, and changes in regional body composition. We also undertake specific measures to determine your risk of Type 2 Diabetes and heart disease. 

Dr Jarrod Meerkin was so lovely and made me feel very at ease.  The scan is non-invasive and you remain fully clothed the whole time.  The only thing that is uncomfortable about the whole thing is the amount of time you need to remain still!   Basically, all you need to do is lie down on a bench and the scanning device passes over your body.  The whole process takes about 5 minutes.  It’s that easy.

My Results:

Firstly, he told me that my bone density was excellent.  It is so good that it is actually off the charts for my age.  How you like them apples??

Then he moved onto the real reason I was there – to learn more about how much fat and muscles my body holds.

My overall body fat percentage was 27.6% (women should be between 21 – 33%).

Jarrod explained to me that the percentage number is not the most important factor here.  What is more important is the actual fat mass and lean muscle mass that your body holds.

I have 18.5kg of fat mass and 45.8kg of muscle mass (which he said was very good).

The total fat mass of females should weigh between 20kg – 25kg.  He explained that anyone who falls between 15kg and 20kg is doing very well.  Professional female athletes sit between 10kg and 15kg of fat mass therefore this is now my goal.

Body Part Breakdown:

Each arm: approx 1kg fat mass; 2.2kg muscle mass
Trunk: approx 6kg fat mass; 23kg muscle mass
Each leg: approx 4.5kg fat mass; 7.8kg muscle mass

So How Do I Get to My Goal?

The coolest part of the whole process was when Jarrod broke down all the information in order to develop a plan and helped me set an initial goal of getting to 23% body fat within 12 weeks.

Using the information from my results he calculated that my BMR is 1565 cal/day (the amount of calories your body needs to just maintain life).  To get to 23% I would need to be at a weight of 63.9 – 64.9kg.  To achieve this I will need to lose 4kg of fat (which would bring me to 14.5kg of body fat) and gain 1-2kg of muscle.  To achieve THIS I need to modify my diet and expend a MINIMUM of 1800 cals per week on exercise (too easy!).

Then he gave me my new calorie and macro requirements: 1900 cals per day; 166g protein; 143g of carbs and 74g fat (fat total is to be divided by 3 – 1/3 sat fats and 2/3 poly and monounsaturated fats).

I’m excited to punch all the numbers into Calorie King and develop a new meal plan!  Yay!  More food!

For those in Sydney, you can get it done in Pitt Street at http://www.bodycomposition.com.au/

Prices are here: http://www.bodycomposition.com.au/index.php?pageid=2 (I had the short consult)

Moral of the story – whether you are serious about making gains or loses, get this done. You will not regret it.

The scans are clearly VERY flattering... haha

  2. Shelley August 3, 2011 at 12:55 pm #

    Fascinating! I really like how it breaks everything down for you so you now know exactly how much to eat / burn and even how much protein, I want to get this done now!

    • Amanda August 3, 2011 at 1:13 pm #

      Yes, it’s so AWESOME. 😀

  3. Tina August 3, 2011 at 1:35 pm #

    I really want to get this done and will be doing so towards the end of the year when my overseas trip isn’t taking all my money lol. Great results on yours! I didn’t realise they actually break everything down too, awesome.

    • Amanda August 3, 2011 at 2:38 pm #

      Haha! Yeah I didn’t realise either so was very pleased when I got all this information! 😀

    This is sooo interesting… Did you get the full consultation? Does the quick scan give you the breakdown of the body parts as well? Are you able to claim some through your health fund??

    • Amanda August 3, 2011 at 6:03 pm #

      Hi Jing! I had the 30 min consult.

      You will need to email Jarrod for information on the quick scan and information on claiming through your health fund. 🙂

      • Jing August 5, 2011 at 12:03 pm #

        Wow, 30 min consultation gave you so much information already. That’s awesome! Really tempting…

  5. jovvie August 3, 2011 at 6:30 pm #

    Ohhh, I’ve wanted to get one of these done since I found out about them. Like others I wasn’t aware that it broke down everything so you know exactly what to do to get the results. AMAZING! I think as I progress I will definitely get one done to help me reach my goals. Thanks for being the guinea pig!!!

    PS – Made your turkey meatballs the other night (with some adjustments like adding carrot and onion) they are awesome. Have also found myself some quinoa, and loved it!

    • Amanda August 8, 2011 at 2:56 pm #

      Yum! Glad you liked them! And quinoa is the BEST. 😀

    Very interesting. I am going to put this on my rewards list for losing weight. Thanks for the break down. I’m super surprised you are not lower actually cause you look so little! Which actually is helpful for me assessing what kind of % I’m actually after.

    As always Amanda… helpful with a dash of humour! Thanks 🙂

    • Amanda August 8, 2011 at 2:55 pm #

      You should definitely do it! Such a cool experience. 😀

  7. Jing August 5, 2011 at 12:29 pm #

    Hey Mandy, I just booked in the short consultation on next Thursday. 😉 Just found out that they are really close to my office as well. Looking forward to the results.. Thanks a lot for sharing this with us~~!!

    • Amanda August 8, 2011 at 2:52 pm #

      AWESOME stuff Jing! Let me know how you go with it! 😀

  8. Darvis Simms August 6, 2011 at 6:02 am #

    Very cool stuff!

  9. callie August 11, 2011 at 5:46 pm #

    booked in too thanks to your review!! next tuesday morning

    • Amanda August 12, 2011 at 4:36 pm #

      Great! I hope you get as much out of it as I did!

    I went there today. Jarrod said you don’t need to put on weight of muscles to lose fat. You just need to work your muscles as hard as you can. My muscles weighs 32.5kg and he said if I want to keep it at that it’s completely fine. My fat weighs 15.6kg, which I would need to lose some of. Amanda, your bone density is REALLY good. Mine is just sitting on the middle line for my age. Doing this scan makes me realise how different the % result is from those skin fold machines the gym PTs use..

    • Amanda August 16, 2011 at 5:36 pm #

      That’s awesome Jing! Glad you liked it. I DO need to put on muscle though because I have the goal of competing. Jarrod understood this to be my goal hence he gave me those recommendations. Building more muscle will also accelerate fat burning. 🙂

      I have no idea why my bone density is so good! Haha I suppose it could be the reason why I haven’t broken a bone! Knock on wood!

      • Jing August 17, 2011 at 11:45 am #

        So do you also want to change your career path and become a full time fitness trainer? You’ve done an amazing job. Such willpower!!!

      • Amanda August 17, 2011 at 2:15 pm #

        I certainly do! 🙂 And thank you!

    Aw you got just as much info in your short session as I did in my long one, lol. Good for you I suppose! When are you getting a follow up? I’m not sure if I should wait 3 or 6 months. I’m not planning to compete but I’d like to look like I do, haha. I was at 21.5% bodyfat.. Need to get the muscle mass up though!

    • Amanda October 4, 2011 at 2:17 pm #

      I’ll go again in a couple of months! 😀 That’s amazing BF! Well done! 😀
