When my husband had his RNYGB, he was advised to drink nothing but Protein shakes two weeks before surgery, and Clear liquids two days before.

When I did the nutrition consult for a gastric sleeve, I was told "Follow South Beach" minus the carbs.

Now, my surgeon for my RNYGB said "Vegetarian diet, with Protein Shakes."

I understand liver shrinking--I just don't get all the different ways folks are doing it.

Is this something that is actually standardized, or is a matter of personal preference on the part of the surgeon?

from what I can see on the boards, it can vary considerably depending on the surgeon.

As many as there are stars in the sky, at least that's what I think!
