What is a typical pre-op diet and how long does it last?



Recommended Posts

I'm very concerned that I won't be able to follow a pre-op diet. I have an enormous appetite. I have never been able to diet for more than a day. Anyone have any tips that will help me not eat during this period?

From what I've read, it seems like most programs have a 2 week liquid diet in order to shrink liver size and make the surgery easier and safer. During that time, you should have at least 3 Protein shakes a day, and sugar free Jello or popsicles, if they are permitted. Also, tell your surgeon/dietician your concerns. Maybe they can help you.

I was not required to have a liquid diet. I had a 1200 calories diet for 2 weeks and was fine with that. Maybe that's an option for you?

Even I am worried about the 2 week pre op diet as I am not able to tolerate hunger for very long period of time. The 1200 calories seems reasonable but ,the pure liquids for 2 weeks will be a bit tough for me.

I had a huge appetite as well and not a good track record for any kind of diet. I am one week in on my liquid diet. I am allowed 4 Protein shakes, 8oz of skim milk, 1 sugar free fat free pudding, and one low carb yogurt per day. As well as unlimited amounts of sugar free caffeine free drinks. The first few days were pretty tough but I have my eye on the prize. The more I drink the better I feel.
I know everyone feels differently about this but for me what has helped is weighing myself every day. I am down 10lbs already in one week. I only record my weight once a week but the daily weigh in right now helps me focus on the positive of this diet. Hey, I figure that not weighing myself at all for years is how I got here in the first place. It works for me. I also have the awesome support of my husband who when I complain motivates me by telling me how awesome I am doing and that I can do it!

You can do it! Use the forums for support and feel free to message me anytime! Best of luck to you!!

My surgery date is May 16, so I start my pre-op diet this Friday. My instructions are more of a Protein diet than a liquid diet. I must stay under 1200 calories per day. But those calories can be used with 4 Protein shakes/bars with around 200 calories each (my choice how I want to alternate them), and one Lien Cuisine meal under 400 calories each. So, 4 Protein drinks or bars and one low calorie meal. Of course, lots and lots of Water too. I haven't started it yet, but I don't think it will be too bad. The protein drinks/bars don't usually taste real good, so I'll be looking forward to my Lien Cuisine meal more than ever! Good luck to you!!!

Try Think Thin Creamy Peanut Butter Protein Bars or Quest chocolate chip cookie dough. They are yummy!

I also think it makes sense to weigh yourself daily on the pre-op diet. People tend to lose a lot on it, and I'm sure it is motivating! Either way, it CAN BE DONE. Know that you can do it. It is done to make you safe and to avoid complications. The end result is wonderful!

surgery is May 5th and I have to do a one week liquid diet. I started the diet diet on Monday April 28th. My diet consists of oatmeal or grits and no sugar. sugar free Popsicles, pudding Jello, all the veggies veggies I can eat. broth and 3-4 Protein shakes a day. I am skimping on the Protein Shakes because I am lactose intolerant. I have been pretty hungry today which is Mt second day, I ate a bowl of grits for dinner and it was so delicious.

i am similar, 2 weeks duration and mine is: 2-3 Protein shakes, oatmeal, applesauce, sugar free pudding, Jello, broths, unsweetened yogurt and unlimited RAW veggies.

i too have a huge appetite but i plan to try and stay distracted as much as possible with cleaning my house, yard, etc as I get ready. i think too that being VERY focused on the surgery date just around the corner will help to keep the days rolling along.

i have to do pre-op over my birthday-UGH...but it could be worse! all this so that on my NEXT birthday, i'll look great and be healthy again.

I am glad I found this thread. I came on today looking for just this. I am on my two week pre op diet. This is day 3 and I am struggling. I want to run out into the street and scream to the top of my lungs, lol. It's been really hard for me. I have locked myself in my room. It's not physical hunger, it's head hunger. I just want some bread or some chips or a cookie, lol. But I know I can eat it. The Protein has me satisfied and not physically hungry but I want some kind of snack. Damn have I been sleeved already, i keep asking myself, lol lol lol. Im stressed out and this is when i would normally stuff my face. Typing and talking to you all is taking my mind off of it and i feel better expressing it now. At least I know what head hunger feels like before hand. I'm sure by tomorrow or so I will feel better. Arrrrrggggghhhh! Good luck everyone!

I have yoyo dieted forever but I did lose 60 lbs and kept it off for 7 years! Some of the things I did were to keep my mind and hands busy. I walked, walked, walked. I knit, read, sewed, got out of the house so I wasn't sitting around bored.

Do things that keep your hands busy. If your hands are busy you will be less tempted to eat.

Thanks for all the replies everyone! Come to find out I would have to gain almost 30 lbs to be eligible for surgery. Instead I have chosen to pretend I just had it and I've discovered some amazing answers to my weight issue. Many from reading this site.

I am recording everything I eat on Sparkpeople.com. It keeps up with your calories, fat, Protein, Water intake, and carbs. Super easy way to see exactly what I am getting too much or not enough of.

I am eating just as if I was heading into surgery. Guess what? I am enjoying food like never before and staying at 1200 cal a day. I am no hungrier than I was when I was eating everything in sight. Less I think. Staying away from all sugar and sugar substitutes has calmed my appetite in a HUGE way! I guess it's keeping my blood sugar stable.

Prayers that I can keep this up. I can hardly walk as it is with all my feet/knee issues. Good luck to all with your surgeries. I was so depressed when I was told I wasn't fat enough to have the sleeve. Now I'm happy about it. It's forcing me to deal with my eating in a whole new way.

I'm on day 2 of the 7-day liquid diet. Not too bad so far except for a really bad headache last night. I'm having som ehunger pains now and I've already had my protien for the night. I can't stand my Protein Shake made with Water instead of milk, but I'm forcing it. Keep telling myself only x-days to go. I have vanilla Protein Powder and put in some vanilla flavoring and a small amount of honey...still it's pretty yucky without the milk. My surgery date is May 7th.

I didn't have the 2 week liquid diet I had to lose 10% of my weight however I could. So I have 3 balance bars a day with a sensible meal and lots of Water. I had the lap and in 2009 and they made me do medifast for 4 weeks with no solid food at all it was torture and I am so glad I didn't have to do it for the revision to the sleeve. My surgery is this coming Thursday May 8th, I couldn't be happier that I chose to have the band removed.

      2 days until I fly out to San Diego to have my Bypass Surg. in Tiajuana Mexico. Not gonna lie, the nerves are starting to surface. I don't fear the surgery itself, or the fact that I'm traveling alone, but its the aftermath that I'm stressing about the most, after this 8 week wait. I'm excited to finally be here, but I am really dreading the post surgical chapter. I know its going to be tough, real tough and I think I'm just in my head to much now that the day i here. Wish me luck, Hopefully I'm one of the lucky ones, and everything goes smoothly. Cant wait to give an exciting update,. If there is anyone else have a June bypass or even a recent one, Id love to have someone to compare war stories with. Also, anyone near San Antonio Tx? See ya soon with the future me. 💜

      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.
