My advice is do it all! Eat what your body is comfortable with. I'm having my takedown in 2 weeks and having pizza tonight as I know it will be a long time if ever again that I eat pizza. I never really got my strength back to full speed so I only do very light exercise but if you're well enough get as strong as possible and keep up the exercise as surgery 2 is suppose to be tough..definitely get out and about as much as you can..good luck to you
