maporsche, in addition to the food in your system, there's probably some water weight from the unexpected sodium intake too.
I weighed my all time lowest on my home scale yesterday - 174! The weigh-in that counts will be at my Weight Watchers meeting on Wednesday, though. The one that really, really counts will be two weeks from Wednesday when my regular leader comes back from vacation.
My goal of 159 seems more achievable lately. More muscle, less fat.

(Though there's still plenty of fat, believe me.)
