Every day. It keeps me motivated and let's me see right away that my weight goes up if I cheat.

Every morning. I also keep a log of what I eat so I can see how it correlates to my loss. Some things do trigger a gain with me, so at least I can keep track of those items. It also keeps me on the right path. The way that I ended up gaining so much of my weight back was that I avoided the scale. It is a great wake up call for me.

I know that a lot of people can't handle the daily weigh ins. I don't get discouraged if the scale goes up 1/2 a pound or so. I know that it is water, but for some, that can cause trouble. It all depends on how sensitive you are to the numbers.
