Body Fat Estimator May 10, 2006

With the improvements that are constantly being made to the Physics Diet weight loss tracking site, I wanted to estimate what my starting body fat % would have been. I only bought a body fat analyser recently, so I wasn’t taking measurements back then.

I know it’s only a rough guide, but I did find this cool Body Fat Estimator. It requires your weight and height in order to give an estimate, although if you happen to know your waist size it’ll be more accurate.

If, like me, you have no idea what your waist size was, you can get out your old belt and measure the distance from the buckle to the hole you used to use. If you’re not sure which hole that was, look for the one that’s had the most wear!

According to that calculation, my body fat percentage back at the start was 42.8%. So, my starting and current stats are:

Body Composition
Weight (kg) Body Fat % Fat Free Mass (kg) Fat Mass (kg)
Starting 110.0 42.8 62.9 47.1
Current 95.4 32.9 64.0 31.4

As you can see, my fat free mass has increased slightly (I guess I’ve built a little muscle through increased exercise), and my fat mass has gone down significantly. Gotta be happy with that!
