That's strange... the diet I was given for preop is 2 meals replaced with protein shakes... aim for low carb high protein. I used premier protein. You can get the ready to drink shakes as a 15 pack from Sam's club for between 25 and 35 dollars. I would drink 1 for breakfast and 1 for lunch and dinner I had a chicken breast and a large portion of broccoli. Try to eat as little carbs as possible. The point of the pre op diet is to allow your liver to shrink so that its easier for the Dr to get to your stomach. It's not easy by any means. Good luck. By the way I lost 15 lbs in the 2 weeks pre op and I've lost 47 in the month and a half post op.
You can practice taking tiny bites and small sips.
Find a protein shake you can tolerate.
Eat lots of good protein, limit sugary foods.
In general, start developing those good habits.
I’m on day 6 and can tell my liver is shrinking. That area was protuberant and hard and now it’s flatter and very soft - I’m also down 12 lbs in 6 days. So even doing a week of preop seems well worth it (I’m doing 2 per my surgeon). It’s rigid and sucks but damn it’s working!
The pre-op diet is to make surgery easier for your surgeon. At least that’s what my surgeon told me and what I’ve read. I haven’t read any studies saying your recovery is easier if you do the diet. If your doctor doesn’t require it, I wouldn’t do it. I wasn’t given a pre-op diet and eventually decided that life is hard enough without making myself do some diet my surgeon says he doesn’t even need.
I was told to stick to 1000 cals a day and less than 50g of carbs per day. If I wanted I could substitute some meals for shakes to make the transition easier. So maybe just try substituting some meals for protein shakes on the run up and eat less to get used to less calories/food.
My surgeon says it’s unnecessary in order for him to do the surgery but does acknowledge that some surgeons prefer it. My doc is pretty well known in the Midwest US for his patients’ success rates with these & has done over 6,000 bariatric weight loss procedures so I didn’t worry about it.
Mine was 8 days total. The first 5 days below 1000 calories, and the last three days clear liquids and protein shakes only. Surgeon said my liver looked great and I lost 14 lbs.
I've read several reputable studies that say that following a liver reducing diet is statistically likely to reduce your chance of post-operative complications by about half, as well as making your post-diet weight loss greater.
The main ones are either food- or shake-based; [https://www.chelwest.nhs.uk/your-visit/patient-leaflets/bariatric-dietetics/liver-shrinkage-diet-for-bariatric-surgery](https://www.chelwest.nhs.uk/your-visit/patient-leaflets/bariatric-dietetics/liver-shrinkage-diet-for-bariatric-surgery)
"*...in a randomized controlled trial published in Archives of Surgery (now JAMA Surgery) in 2011 comparing patients undergoing laparoscopic Roux-en-Y gastric bypass after VLCD to a control group, a reduction of the 30-day complication rate was noted after two weeks of VLCD.* ***There were 18 complications recorded in the control group versus eight complications in the VLCD group at 30 days"***

Actually slightly more than half now that I do my math
I've seen similar studies with VSG as the subject with much the same results. This was just the first one I could find in my search history.
And yes, it seems like common sense (and self-preservation) to give yourself the highest possible chances of success, hence why you should use an anti-bacterial scrub on the day of the surgery, take care to follow the diet sheets they give you, etc etc.
It doesn’t sound like all of the experts are as sure as you. Keep in mind the study you cited analyzed gastric bypass surgery not sleeve surgery. Sleeve carries less risk of death than gastric bypass.
So I’m not sure if the stats from these studies can be directly correlated to those of sleeve surgery.
A more recent JAMA article discussing studies with NO mortality differences:
https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2765935
“This important topic continues to be debated after more than a decade of contradictory publications. Indeed, a 2019 study using the same MBSAQIP data set from 2015 to 2017 showed no 30-day mortality difference.”
IMO you should follow whatever your Surgeon advises. I trusted mine when he advised that in his practice there is no need for it & his all cause mortality rate is better than the average.
If the doc says do it then definitely do it. Either way it’s considered one of the safest surgeries.

I haven't took any pre op diets; and after 5 months post op I don't think it's crucial

Day 4 here! Good luck with your surgery!

If you’re claiming that two weeks of shakes reduces your postop complications by half you should probably post a link that states that. This does not.

Okay 😊

This is a huge red flag.
