On December 18th, 2017, I (
finally) completed BBG 2 (click here to read my review about the program). After watching a video from Anna Victoria testing her body fat and explaining that our home scales does not tell us the truth, I decided to get a Dexa (or DXA) scan, in order to see what my body is made of.
Some advanced scales (like mine) are able, by a painless low intensity electric current to measure the weight, bone density, lean mass, water and fat percentages in our bodies. However, this information is not always precise. It is good to have a weekly update (like shown below) but it should not be taken too seriously.
Therefore, I wanted to go for a Dexa scan to be aware of my real body fat and lean mass percentage. The Dexa scan can measure it very precisely, giving data for each body part. In Paris (where I live), there are only 2 dexa scan available: at Mon Stade (Paris XIII – where I went) another one for high level athletes, in CNF I believe.
The test costs 60 euros and is really quick, the coach (who by the way was very nice) measured the circumference of my height and hips, before launching the Dexa scan. It is funny because it doesn’t work the same way than in North America. I was able to talk and the big arm (see picture below) was going back and forth a few times to scan my own body. In North America, it is done in one shot and Americans are not able to talk during this whole time. This test takes around 7 minutes. The last part is impedance test, which measures body water (and therefore body fat and lean mass), thanks to two electrodes on the hand and two on the leg/foot. This test takes 30 seconds. Both tests are absolutely not painful, the radiation of the Dexa scan is much lower than a X ray, and they both require lying down.
Here is the interesting part: I filed a satisfaction form while my results were being printed and I got my results explained with the coach (you can see them below). I have 29% of fat (my scale was indicating 17.1% and high level athletes are around 15%) and overall, I am healthy, I eat very healthy and my fat percentage is lower than women of my age (you can see that on the graphic on top right, the limit between the dark and the light blue is the average women’s body fat). The graphic of my body tells where my fat is. Here, it is on my arms, hips and thighs. The following picture represents my bone density. And here, my bone is at around -2.5, which is a high risk of osteoporosis (when bones can break in a million pieces because of a lack of calcium and D vitamins). I do eat calcium (dairy products and water) so I decided to take organic D vitamins supplements, which we do need since we do not receive this vitamin through the sun. I also have decided to eat more cod liver (it is not too bad on toasted bread).
My basal metabolic rate is 1385 calories per day. It is how much calories I burn if I lie in bed all day without doing anything. Therefore, he recommended me to eat more and to do more HIIT sessions to lose weight and body fat. He also recommended to eat more calcium and D vitamins for my bone, as well as perform more “contact sports” such as running and boxing.
When I first had these results, I was disappointed and demotivated. I met my mom for lunch, had a big vegetarian burger with a piece of chocolate cake and felt really heavy to workout. When I got home on that day, I put the test results in my desk drawer and decided to not touch it anymore. But I am very happy I did it for 2 main reasons: First, I am healthy. I know where I am and where I am going. I know I now need to continue to eat the same kind of food because it is good for my body, and I need to focus my training on HIIT and building muscles (to burn fat) by using the gym machines. This is why I subscribed to Kayla Itsines’ Sweat app as my BBG 3 training. The second point is regarding my bones. I now know I have this issue and I am so glad I found out at a very young age, before having any pain or a broken bone. I now know that I have to take care of this, that running is actually really good for me, and that I have to take D vitamins as a life supplement to be healthier. My goal is now to burn 10% of fat and redo the test within 6 months!
