2 week pre-surgery diet



Recommended Posts

For some reason I want a list of the liquid diet allowed foods for my 2 week pre surgery diet. I think I want to test different flavors, etc, and know what's allowed and what isn't. To prepare myself. My "coach" says Ill get it at my nutrition meeting, which isn't for a month. Anybody?

Pretty basic really. Clear Protein, Protein Shakes, Bone Broth with protein, chicken or beef broth, Water, gatorade zero, sugar free pudding or Jello, pretty much it....

They can't really be considered food, but sugar-free popsicles are an enjoyable treat for me.

I don't think sugar-free pudding counts as a "clear liquid". It's a soft liquid.

According to my team it was fine.

My pre op allows 1/2 cup oatmeal, sugar free pudding, sugar free Jello, and unsweetened apple sauce as Snacks. Protein Shakes for the meals. Will probably use premier and fairlife for the shakes. I bought some isopro fruit punch Protein to try with Water in case I get sick of the shakes.

Bravo! Those Snacks aren't going to lead you to binging. :) Much better to use these than the so-called Keto snacks or Protein Bars (which are no better than candy bars). I don't care if bariatric sites sell low-cal/low-carb snack food, they are not good for us because we are too prone to binging, snacking, and grazing.

Good luck with the Isopro fruit punch.I don't like it at all. I can tolerate it only if I mix it with sugar-free lemonade or flavored water. You might do better to add unflavored Protein Powder to Water flavored with Wyler's, Crush, Sunkist flavor packets.

Try some plant based Protein Drinks, too, I prefer them to whey-based. Orgain and Purely Inspired are brands like but there are others,

I was on a 10 day clear liquid diet so it is different than a regular liquid diet. I found this on the net and it is a good source for your liquid diet.

"The 1-2 week pre-op diet will include the following elements:

  • Protein Shakes or Meal Replacement shakes will be the diet’s primary component.
  • Only sugar-free beverages are allowed (sugar substitutes are okay).
  • No caffeinated or carbonated beverages are permitted.
  • Soup broth with no solid pieces of food may be consumed.
  • V8 and vegetable juice are acceptable.
  • Extremely thin cream of wheat or cream of rice may also be eaten.
  • One or two daily servings of lean meat and/or vegetables might be okay, but only if they are approved by your surgeon or registered dietician."

Are Soup broth and Bone Broth considered the same for the pre diet? I plan to ask at my pre op appt, but just wondering. I’m going to check my local GNC for unflavored Protein powder so I’ll have more flexibility with flavors.

From what I understand, as long as there are no bits and pieces, both are fully accepted. On my clear liquid diet which is more strict (I hated it lol), Bone Broth was encouraged. My favorite Protein is GENEPRO. I even use it in my coffee lol.

My pre-op was 3 VLCD Protein Shakes a day, and I had to have 2 cups of low carb/non starchy vegetables, which could be prepared as salad, Soup, stir fry (soy sauce was allowed), or a stew. I made a huge pot of vegetable stew that got me through. All spices and herbs were allowed, so I was free to make it tasty.

It was meant to be an Opti-fast pre op diet, but I can't have Opti-fast so this was my dietician's vegan workaround.

Every surgeon requires a different pre-op diet. Mine wasn’t even a liquid diet, just Protein based. I had to buy a ‘Bariatric box’ that included things like chicken nuggets, bread, pancakes, Soups and Desserts. I had to eat 6 meals a day and every meal was different. It was absolutely awesome. I was never hungry (even though the meals were only 80-100 kcal per meal) and most things tasted really good. But like I said, every surgeon has his own pre-op diet. My surgery was in Belgium.

Hi! I am in my 2nd pre op diet stage right now. My surgery (roux ny gastric bypass) is next Wednesday. Right now I can have 4 Protein Shakes a day plus broth, sf Jello and sf popcicles. What has got me through is being creative with flavors. I have chocolate, vanilla and strawberry whey Protein isolate and I use sf pudding mix and/or sf syrups to add flavor. My favorite combination is strawberry with 1Tbsp sf cheesecake pudding mix, it is bomb!

My "full liquids" was much like Tony B - NJ's, plus I am allowed to have kefir, Greek yoghurt, and skyr as long as it's not fatty and not got much sugar in it.

Your preop diet may be all liquid but mine was 14 days of low calories with 2 days liquid. I was allowed meat, cheese and veggies on mine. Best to just wait and see what your clinic provides material wise to start.

      I am new here today... and only two weeks out from my sleeve surgery on the 23rd. I am amazed I have kept my calories down to 467 today so far... that leaves me almost 750 left for dinner and maybe a snack. This is going to be tough for two weeks... but I have to believe I can do it!

      Hey everyone. I'm new here so I thought I should introduce myself. I am 53y/o and am scheduled for Gastric Bypass on June 25th, 2025. I'm located in San Antonio, Texas. I will be having my surgery in Tiajuana Mexico. I've wanted this for years, but I always had insurance where bariatric procedures were excluded. Finally I am able to afford to pay out of pocket.  I can't wait to get started, and I hope I'm prepared for the initial period of "hell". I know what I have signed up for, but I'm sure the good to come will out way the temporary period of discomfort and feelings of regret. I'd love to find people to talk to who have been through the same procedure or experience before. So I look forward to meeting you all. Hope you have a great week!

        I'm so happy for you! You are about to change your life. I was so glad to get the sleeve done in Dec. I didn't have feelings of regret overall. And I'm down almost 60 lbs. I do feel a little sad at restaurants. I can barely eat half a kid's meal. I get adults meals often because kid ones don't have the same offerings at times. Then I feel obligated to eat on that until it's gone and that can be days. So the restaurant thing isn't great for me. All the rest is fine by me! I love feeling full with very little. I do wish I could drink when eating. And will sip at the end. Just a strong habit to stop. But I'm working on it! You will do fine! Just keep focused on your desire to be different. Not better or worse. But different. I am happy both ways but my low back doesn't like me that heavy. So I listened (also my feet!). LOL! Update us on your journey! I'm not far from you. I'm in Houston. Good luck and I hope it all goes smoothly! Would love to see pics of the town you go to for this. I've never been there. Neat you will be traveling for this! Enjoy the journey. Take it one day at a time. Sometimes a few hours at a time. Follow all recommendations as best you can. 💗

        Thank you so much for your well wishes. I am hoping that everything goes easy for me as well. We don't eat out much as it is, so it wont be too bad in that department. Thankfully. Also, I hear you regarding your back and feet!! I'd like to add knees to the list. Killing me as we speak! I'm only 5' so the weight has to go. Too short to carry all this weight. Menopause really did a doosey on me. (😶lol) My daughter also lives in Houston. with her Husband and my 5 grand-littles. I grew up in Beaumont, so I know Houston well, I will be sure to keep in touch and update you on my journey. I may need some advice in the future, or just motivation. Thank You so much for reaching out, I was hoping to connect with someone in the community. I really appreciate it. 💜

      On day 4 of the 2 week liquid pre-op diet. Surgery scheduled for June 11th.
      Soooo I am coming to a realization
      of something and I'm not sure what to do about it. For years the only thing I've enjoyed is eating. We rarely do anything or go anywhere and if we do it always includes food. Family comes over? Big family dinner! Go camping? Food! Take a short ride or trip? Food! Holiday? Food! Go out of town for a Dr appointment? Food! When we go to a new town we don't look for any attractions, we look for restaurants we haven't been to. Heck, I look forward to getting off work because that means it's almost supper time. Now that I'm drinking these pre-op shakes for breakfast, lunch, and supper I have nothing to look forward to.  And once I have surgery on June 11th it'll be more of the same shakes. Even after pureed stage, soft food stage, and finally regular food stage, it's going to be a drastic change for the rest of my life. I'm giving up the one thing that really brings me joy. Eating. How do you cope with that? What do you do to fill that void? Wow. Now I'm sad.

        I hope your surgery on Wednesday goes well. You will be able to do all sorts of new things as you find your new normal after surgery. I don't know this from experience yet, but I am seeing a lot of positive things from people who have had it done. Best of luck!

        Life as a big person had limited my life to what I knew I could manage to do each day. That was eat. I hadn't anything else to look forward to. So my eating choices were the best I could dream up. I planned the cooking in managable lots in my head and filled my day with and around it.

        Now I have a whole new big, bigger, biggest, best days ever. I am out there with those skinny people doing stuff i could never have dreamt of. Food is now an after thought. It doesn't consume my day. I still enjoy the good home cooked food but I eat smaller portions. I leave food on my plate when I am full. I can no longer hear my mother's voice saying eat it all up, ther are starving children in Africa who would want that!

        I still cook for family feasts, I love cooking. I still do holidays but I have changed from the All inclusive drinking and eating everything everyday kind to Self catering accommodation. This gives me the choice of cooking or eating out as I choose. I rarely drink anymore as I usually travel alone now and I feel I need to keep aware of my surroundings.

        I don't know at what point my life expanded, was it when I lost 100 pounds? Was it when I left my walking stick at home ? Was it when I said yes to an outing instead of finding an excuse to stay home ? i look back at my last five years and wonder how loosing weight has made such a difference. Be ready to amaze yourself.

        BTW, the liquid diet sucks, one more day and you are over the worst. You can do it.
