  • Keep in mind that if you're biking often (especially up and down hills) there's a good chance you're building leg muscle. That means you could be losing fat without losing weight.

    A body fat measurement is in order I think. Then, another one every 3 months or so.

      I got ahold of a scale that purports to measure body fat percentage electrically. Its reliability is horrendous, however. It varies extremely based on the moistness of the bottom of my feet, in addition to other factors I can't fathom. I figure it's better than nothing, though, and I track and trend my body fat percentage daily with the same calculations I use for body weight (from the Hacker's Diet). I figure eventually it would be nice to get a real measurement done, with caliper or even better, with submersion.

      • I've got one.

        I was also a metrologist [gems-calibration.com] for 13 years... take that for what it is worth. Throw in a few bucks and you can buy a cup of coffee somewhere...

        Anyway, you are right about the variation. But, from a measurement standpoint, that is to be expected. (Consider, the thing shoots an electric current from one leg to another. The current has to pass thru (and along... there are multiple paths) one leg, the core of your body, and down the other leg. Anything that changes the current flow will change the rea

        • You should make sure your feet and the unit are dry.

          Actually the instructions for this unit say your feet should be somewhat moist. That's kind of annoying, as "somewhat" moist is nowhere near precise. I usually don't worry much about it, but I usually weigh right after my morning shower, so my feet are in some varying stage between dry and sopping.

          You're right, you can't get too hung up on the numbers. I keep the info, but if I ever got really serious about it, I'd have to find a more accurate met
