I've become a little obsessed with tracking my weight-loss progress, and so yesterday I bought a digital scale that also uses BIA—in other words, electrical resistance—to calculate body fat percentage. The body fat calculation is not guaranteed to be accurate, but it is promised to give consistent results so you can chart relative progress.

I've been stalled in the low 200s weightwise, and the inconsistent zeroing of our analog scale was making it hard for me to know how I was really doing on a relative basis day-to-day. Hopefully the digital scale will change that. By the way, I was 204.0 lbs this morning. The body fat percentage is my business.
