Chuck out the scales and just weigh on your CDC one! I know its tempting, very tempting, but it screws with your head. It doesn't give you a true picture, instead just giving you something to worry about which you SO don't need. Once a week is enough - look at the big picture! I have (so far) resisted the scales - i deliberately didn't find out what 'my' scales said on the day I weighed on my CDC scales, thus I can't know whether I am up, down or sideways from that number and there's no point in getting on them now. I'm looking forward to a surprise next Wednesday (nine day week!)
honestly, it doesn't help matters, so why bother?!
