I'm almost 2 weeks into my 3 week pre op diet. I've lost 15 pounds or so but have substituted allowable Proteins for shakes most of the time.

I've logged all foods consumed and kept the carbs low and Protein where I'd should be.

I thought I was allergic to whey as I got a rash after first Day of shakes but not sure now. My nut said it was ok to substitute proteins on list for shakes but I think my surgeon would get mad if I told him I did this. Tomorrow is my weigh in appointment and surgery in one week.

Should I tell my surgeon about the shake replacing or not bring it up?

Does your nut work for your surgeon? If yes, why would he get mad?

Two reasons for the pre-op liquid diet: 1) to shrink your liver to make it easier for the surgeon to perform the sleeve surgery; and 2) get you ready for the post-op liquid diet where you will NOT BE ABLE TO SUBSTITUTE other Proteins for the liquids. Well, not unless you want to blow a staple or 2.

Some other sleevers have said that their surgeons didn't require a pre-op liquid diet. Or maybe just a few days. Others have said that day 3 of the liquids are the worst -- because you are going through carb, sugar and caffeine withdrawal by day 3. I sure wouldn't want to be going through withdrawal AND recovering from surgery at the same time.

I am not a perfect person. I did 2.5 weeks of liquid diet before surgery. I did have a few bites of chicken about 1 week in, but then back to the liquids. My withdrawal wasn't too bad as I had given up sugar and caffeine years ago. My surgeon said my liver was really small, and he had no problems during the surgery. Indeed I had no complications, no vomiting, no nausea, no real pain. I followed the post-op diet well. I couldn't handle the puréed diet, so because I was complication-free, my nut let me go right to soft foods.

Whether or not you tell your surgeon about your pre-op diet is up to you. I wouldn't want to hide anything as I was putting my life/health in his hands. But definitely I think you should go to all liquids starting NOW.

Good luck on your journey. It's going to be amazing!

Very interesting.

I had an appointment with my surgeon yesterday, one week before surgery. I came clean about changing the plan, reducing the use of the shakes. However, when he realized that I'd lost 26 pounds in 3 weeks he told me to keep doing what I'm doing .
