I've been on the 2 shakes a day and one diet dinner since last Tuesday and have only lost 3 lbs. Does anyone know how much weight we need to loose during the 2 week pre op diet? I've seen where some have lost 20 lbs in these two weeks and I've only lost 3 in one week urgh....

It all depends on your doc when I am actually on my pre op diet 2 weeks before surgery I wont have to lose anything, just can't gain. But on a calorie intake of 1200-1600 my nutritionist has me on for insurance purposes...I have lost 12 lbs in a month

I had to do 1 week pre-op of shakes w/ lean protein/veggies for dinner. I lost 6 lbs. In the two weeks since my surgery I lost 2lbs, started mushies, and have gained them back. I think alot depends on your starting BMI. Mine was 31.7. I feel like I am one of the only people that has lost such a small amount initially....

It doesnt matter what you actually loose as the pre op shakes are actually to cleanse the liver - to make it easier for surgery Dr's require you to do the shakes to get rid of the fat on your liver so it's easier to do surgery when it comes around to it - obviously loosing any weight is great but don't get bummed just because you only loose a little - overall if you loose fat on your liver that's the best thing overall

yes, what sarah said agrees with what my doc said, specifically that there IS NO WEIGHT LOSS goal for the pre-op diet--it's all about shrinking the liver as much as possible so that it doesn't get in the way during the surgery. the more faithful you are to that pre-op diet, the easier the procedure goes (and the better your recovery!!!) Apparently, when you diet like that, the liver loses weight first :P

My surgeon did not have a pre-surgical weight loss requirement. The purpose of the liquid diet was to shrink the liver for surgery. Weight loss was a nice plus, but not a necessity.

I am on the liquid diet post op and have lost around 17 lbs. in a week and a half. But I think it is much different after the surgery then before.

Good luck to you.

I know it is really hard not to compare yourself to others, but the reality is that the weight you lose pre-op on the shakes is not true weight. The people who lose massive amounts (me included) on the pre-op diet (I am specifically talking about the shake heavy pre-op diet, although I would argue it is probably true on any pre-op diet) are losing Water weight, not fat.

Many of those same people are really upset after the surgery when they stop losing weight or they even gain weight when they go on mushies. They didn't actually lose fat during that time and once they start to eat real food, their body holds on to it, and replaces the Water lost pre-surgery.

You are doing fine. Just stick to the diet, if for no other reason than to prepare you for the diet restrictions you will have post surgery (it does make it much easier to cope with).

Good luck to you :P

I was instructed to lose 10 pounds in 7 days on 4 MediFast drinks a day and one Lean Cuisine. I really doubted I could lose that much weight in 7 days but my doctor assured me I could. Well, I started the diet a couple of days early (my doctor is known to postpone surgery if you don't lose the weight he instructs you to lose) and I struggled with it. At the end of 6 days I still had almost 3 pounds to lose. So, I changed my diet to three MediFast drinks a day and, instead of a Lean Cuisine, I made a low-carb dinner of chicken breast and green Beans, for the last 2 nights. I ended up dropping almost 12 pounds instead of the required 10. I'm convinced giving up the Lean Cuisines and switching to low carb is what helped me.

Some of it is Water weight but wow I feel better getting that off and feeling less bloated. My ankles don't swell like they did before.

      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. 💗

      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.
