Hi Sara!
Congrats on the 50 lbs loss! Wow! That is spectacular! Plateaus happen and they are no big deal. Look at it this way: They are so much better than gaining! They really are just your body's way of adjusting to the weight you've lost so far. Sometimes, you have to do something a little different to jumpstart your metabolism again like add a different exercise, etc., and sometimes you just have to wait it out. Anyway, so glad to have you here. Be sure to check out the WW forum under Diet Central! Good luck!
