The combination of daily weigh-ins and the exponentially weighted moving average I learned from the Hacker Diet has been absolutely magic for me. It gives me helpful daily feedback signal in the noise of ~5lb daily weight variation. Beeminder has replaced paper graphs for me. Their new moving average isn't quite as helpful for me, but is still workable. I target rates of weight loss on the order of 0.35-0.50lbs/week.
