Hi ladies.
First off, although there is a perfectly great mathematical formula for weight loss, your body does not know that.
Weight loss is not linear, it can bounce all over the place. As long as it's on a downward trend, don't worry.
Skinny, if you were not on plan real well over the holidays, I wouldn't consider it a plateau. Get back on plan, rev up your exercise and losses will start up again.
River, are you doing the old plan or the new one? Maybe you should recalculate your daily points. I know the first time I lost from 195 to 145, the last 10 were stubborn as all get out. Adding some long, fast paced walks on the weekends did the trick. I didn't lower my points, as that was the old plan and I didn't think I could get by on less than 24/day. I have a very active job, and any less just would have left me starving all the time.
My best advice, stick with it, it will work, if you work it.
Hope that helps!
