In tagging along with my wife’s low carb. diet I’ve lost a couple of kilos. Now my BMI is 23.4 kg. One calculator told me something kind of scary: I’m in the 19th percentile for my weight based on my height, age and gender. This means, of course, that 81% of men (U.S., North America?) weigh more than I do.

I dialed in the new weight on the treadmill. It says I expend about 6 calories less over the half hour now that I have shed that 2 kg.

I figure I now weigh about what I was when I was 17 — Before I was of legal drinking age and before I drank beer.
