I think 4 weeks of liquid shakes only is a bit excessive. I was told by my surgeon that I could only drink 3 shakes a day for 2 weeks, but when I did my research on liver shrinkage, what I found was that the goal was deplete carbs. And you can do that with things other than Protein Shakes. Like actual Protein.
So I asked my surgeon why I couldn't just eat chicken breast and eggs all day, every day. He explained that it wouldn't be nutritionally balanced enough, plus after the surgery, my stomach wouldn't be able to handle solid foods for weeks so it was good "practice". I took all of that under consideration, as well as discussions I read about other people's pre-op diets, and went a bit rogue.
I would choke down 2 shakes a day (instead of 3), then eat chicken + non-starchy veggies for dinner. I also drank low-sodium broths frequently because I REALLY don't like sweet things. During the last ~5 days of the diet, I switched to recommended 3 shakes per day to get in that "practice" the surgeon talked about. That slower transition was so much easier for me than going cold turkey. I'm 2 months post-op now and down 42 lbs so I guess it's working.
Not saying you should rebel like I did, but you should at least ask your surgeon to explain his reasoning and maybe bring up some of the above points. See how he reacts.
