a note on methodology
A bit of the Hacker’s Diet, a bit of of other number crunching.
(as they say in science texts)
I’m calorie-counting, because it’s the simplest thing, and I had reasonable success with it several years ago when I did the Hacker’s Diet. (Google it. Entertaining writing, if nothing else.) I’ve done all sorts of wacky math (links to follow eventually) to figure out how many calories in order to lose about a pound a week. That gets me to a healthy BMI in early February, at 158 pounds. (You do the math.)
Also per the Hacker’s Diet, I’m weighing myself at the same time every day and using Excel on my MDA to get a running 7-day average.
For the exercise side, I’m using my kewl Trek cyclocomputer to get mileage, time, average speed, and top speed for my daily biking. Plus I have a pedometer that I got at work to track steps during the day. At least this month, and maybe longer, I’m recording everything in step equivalencies, again because it’s the simplest thing.
So, yeah. Probably not going to write about this too much more. 
I’ve been doing the hacker’s diet since July, and logging at physicsdiet.com. Over 30 pounds so far, for an average of .7 pounds a week. Although this progress seems glacial, I am just happy I am not obsessing about food.
Congrats! I’m still at the obsession stage myself, but trying to pace myself so as not to go entirely crazy. And thanks for the tip on physicsdiet.com — I’ll have to look that up and see if it’ll work for me.
