I've read a couple of books that say you shouldn't weigh yourself, you should judge your weight loss on inches lost or how your clothes fit. I don't know what everyone else thinks, and I know it's not a good idea to weigh more than once a week, but weighing myself is the only way I can judge how well I'm doing. I did start to weigh myself only once a month but I feel personally I need to have a weekly weigh-in to keep myself on track (and hopefully to see those numbers on the scales going down!)
