Plateau Help

Someone please help me...I was sleeved on September 9th and so far I am down 60 pounds.  I hit a plateau a few months ago, that I haven't been able to break even up to now.  I am still not in a healthy BMI.  My surgeon and nutrionist both told me to increase my daily calories, add additional protein shake, work out more, and log my food.  I have been doing all of these things and increased my water intake, but nothing will break this plateau.  My scale usually fluctuates between 190-193 but never goes under 190.  I am concerned and not sure How to proceed and I am becoming discouraged.
