I'm starting to realize that there aren't very many practical and accurate ways for us to gauge body composition/weight/health.

Body weight is misleading because of day-to-day fluctuations. BMI is pretty useless since people have different sized frames. Body fat percentage is notoriously inaccurate unless you use calipers properly or find a place with some fancy equipment. It would be crazy silly to get weekly immersion tests done.

I'd recommend learning how to properly measure yourself with a good, accurate body fat caliper. Since I don't do that, I go with tape measure and the size of my waist (not hips). Or if you don't want to bother with that, just take a look in a full-length mirror with good lighting (or take pictures). To be honest, I think going by appearances is probably better than weighing yourself.
