post-surgery diet?

what are some post-surgery diet rules that i could start looking into now? i know you have to get lean protein first, but what else? i don't know how long it will take me to see a dietician and i want to start making some small changes ahead of time.

no pop,lots of water.i eat very little breads and pastas.they dont sit well with me.i try and eat meat first then veggies.i alway eat protien first.start making smaller portions as you will not be able to eat a regular sized meal.learn to see food differently.play with the reciepes to adjust them to what you can eat.

i hope this helps
