Merry Christmas and a Happy New Year
I was on a no carb diet for 2 weeks before my surgery and i had open rny as well. I lost 19 lbs it was not the easiest thing but it can be done. And the more weight you loose before with the no carbs the better it shrinks your liver which makes it easier for them to get to your stomach(that is what my surgean said and it worked my incision is only 4 inches long and i am doing great. Good luck...
