My weight fluctuates a lot during the day, and day-to-day. So I picked a consistence time and procedure. I try not to over-think it, and simply do the same thing each time, generally, in the morning after I go to the bathroom.
After doing this for a few years, I no longer care about the fluctuations. The whole point of this is to get a handle on the trends. The individual jumping around of the numbers is irrelevant. Once you see the numbers jump all over the place for a few weeks, you learn to stop caring about what the scale says on any given day.
My scale measures in 2/10’s of pounds. So I can get “123.4” or “123.6”. It’s digital, has huge numbers, and it lives right in the open in the bathroom where I can just step on it at any time. This is important as it removes all possible “friction” to weighing myself. I don’t even need to slide the scale out to step on it.
Next to the scale hangs a tailor’s tape measure. I use the metric scale on the tape since that gives me centimeters and tenths. (If I used the inches scale, I’d have to convert the 1/8’s of inches into decimals, so it’s easier to get 4 digits from the metric side.)
I step on the scale and grab the tape measure. By the time I look down, the scale is done deciding my weight. I step off scale and measure the largest circumference. This requires honesty, but is very easy to do once I did it a few times: I just relax, let it all hang out, and slowly let the tape measure slip longer as I try to slip it down around my waist. (I suppose, that some day, when I have a “waist” in the proper definition, I’ll have to tweak my method. That will be a great problem to have.)
I might get 232.8 pounds– I just remember 2 3 2 8.
I might get 110.7 centimeters– I just remember 1 1 0 7.
…and I walk out of the bathroom mumbling, “2 3 2 8 1 1 0 7”
In subsequent posts I’ll go into what I do with the numbers in terms of math, spreadsheets and why the units are irrelevant. But for now, that’s the data capture that I try to do every day. It’s fast and easy. Step on scale, measure “waist”, and record eight digits.
