Good luck! Remember you should always pick one scale as your "official" weigh in scale because scales are calibrated differently and will weigh you something different on each one. They should all be within a few pounds of each other. Doctors scales should be calibrated regularly because many people weigh on the them but many are not. If you are using one at home too, then pick the one you will weigh on weekly/daily so you can accurately gauge your weight loss.
