I bought me a pair of Accu-Measure calipers to try to get a more accurate measure of my body fat percentage. I have been using my Withings scale since day one to track my weight loss. I know scales that use bioelectrical impedance can be inaccurate. So I wanted to try to get a better idea of what I was working with. I got the calipers today and had Shane help me out with the measurements. Surprisingly, it was not that much different then the scale.
When I started losing weight and stepped on the scale for the first time I got a body fat percentage of 50.9. At 396.2 lbs that worked out to 201.6 lbs of fat mass. My most current scale reading is 23.7%. Which at 255.1 lbs works out to be 60.3 lbs of fat mass. That number alone is enough to make me happy with my progress. But was I really making the progress that I had hoped? It was time to use the calipers.
For my measurements I used the Durnin/Womersley four site skin fold method to calculate my body fat. This method uses folds on the bicep, tricep, subscapular and suprailiac. I did a search for an online calculator for this method and found this site.
My measurements were as follows:
- Bicep: 6cm
- Tricep: 12cm
- Subscapular: 12 cm
- Suprailiac: 18cm
