Not a big difference, somewhere between .5 and 1 lb(new one is in .2 increments). But this morning I FINALLY weighed in under 150(149.8, just made it). I started low-carb yesterday - planning to use it until I break through my next two plateaus(how sad is it that I know all my body's set points?) and then will add carbs back gradually, hoping none of the weight comes back. Long-term I don't think it would work for me as I don't eat much meat. Sticking to white meat chicken and turkey, fish, low-fat cheese, and some nuts. I ended up just under 1200 calories yesterday, but will see how I feel and may bump to 1500 or so if my energy lags.
Got my new scale, and it's LOWER! Yay!
