I guess I am the exception. I feel I have to weigh myself almost daily - otherwize I won't keep to it, and get scared of gain again. After the first 15 pounds were gone, most clothes fit loosely, so that was no measure. Early on, when I had just started phase II, it was clear I was doing to many new carbi allowed veggies, and I gained again - then I went back to phase I, and lost it right away again. But without daily weigh-ins, I might have thought I am doing fine one phase II and gained more. Because Atkins is a bit more strict it might not be an issue, but South beach is flexible - one is just supposed to introduce allowed carbs gradually, and that is hard to gage for me without daily weigh-ins.
