Unscientific report on fat/muscle loss

My scales have bio-impedance built in, which means in addition to my weight, they give me my “muscle”, “fat” and “water” percentage breakdowns – ie my body composition. The technology isn’t great yet and I don’t have much faith in the numbers they report, however it is a measurement that can be compared over time.

I could only find 1 recorded measurement of the muscle-mass number and that was for week 18 (28.2%). I hopped on the scale this morning to get something to compare it with (32.2%).

Week 18: 365.2lb @ 28.2% = 103lb
Week 49: 287.4 @ 32.2% = 92.5lb
Difference = 10.5lb

So in 78lb of total weight lost, 10.5lb (13.5%) of that was muscle. That seems like a pretty fair deal to me, even if the numbers are make-believe.

The reason I mention this is because I think my progress over the next 6 months is going to be less about the scale and more about other numbers. In my “3 Chapters” plan Chapter 2, which I’m about to start, is about going from “normal fat person” down to “normal person”, ie continuing my weight loss for another 6-9 months and getting down to my goal of 217lb. Chapter 3 was about then going from “normal person” into “cor blimey, you’re fit!”, where the focus was on body composition and bulging muscles. The reason this might change is the rugby 🙂

Having had a taster of what I was missing, I’m now feeling very motivated to get back into it. I had planned to have a PT re-evaluate my weight-lifting anyway, but with the addition of rugby training, games and my running, I’m getting a little overwhelmed as to what I should be doing. So instead of having a generic PT look at my weights, I’m going to have a rugby strength/conditioning specialist look at the overall picture. Right now I’m not sure what such a program would look like, but I imagine it’ll be more calories and more hardcore training :). That might mean my weight loss slows down, or goes up as I put on extra muscle, so I’m going to need to look at other measurements to track my progress (in addition to the trusty scale of course).

I’m really excited. With my drop to part time work I’m going to have loads of time to dedicate to training, how good is that? :D.
