I'm a technophile, so I use a program on my palm pilot that I got free online at www.hackersdiet.com
. It takes your daily weight measurements and adds them into an "exponentially weighted moving average" - basically a statistical analysis of numbers that gives more importance to the most recent figures. There's a description at that site that tells why it's worth using. Anyhow - the crux of it is that every day, I put in my weight. The program gives me a trend number every day (and prints graphs if I want...but I digress) and if my daily weight is lower than the trend, I'm still losing weight. So that makes it easy to do, and keeps me from freaking out if I'm up a pound or three - as long as I'm not over my trend more than one day in a row, I know I'm on track. But if I AM over trend for a few days, I know I need to look hard at the last few days' eating and activity patterns.
