How much should I be eating after weight loss surgery?



Recommended Posts

Those who have had weight loss surgery often ask how much they should be eating. Whilst is seems a simple question, there is no simple answer.



Those who have had weight loss surgery often ask how much they should be eating. Whilst is seems a simple question, there is no simple answer.

How much you should be eating is a hot topic on many online forums or support pages. If you have read the discussions it becomes clear that weight loss surgery clinics and support teams widely differ in how much they are recommending their patients eat. This is also clear when I chat with other health professionals at our obesity surgery conferences. If the professionals working in the area can’t get their story straight, how are people to know what to do?

Some surgeons recommend you limit meals to half a cup, some may say one cup, and others will say a bread and butter plate of food. Interestingly, one cup of food nicely fits on a bread and butter plate and this is the guide we use in our clinic.

Accredited Practising Dietitians (in Australia, Registered Dietitians in the USA) are university‐qualified experts on food and nutrition. Whilst even their recommendations on what you should eat following surgery will vary, what they will generally agree on is that it is difficult to meet your nutritional requirements eating half a cup of food, three times a day.

To date, there are no scientific studies on the exact amount of food people should include after gastric band and gastric bypass surgeries. Hopefully in time this will evolve. Research from Mercy Bariatrics in Perth, Western Australia, provides some excellent data to help guide serving sizes for those who have had a sleeve gastrectomy. Whilst initially very small amounts are tolerated, at six months after surgery most people will manage about half a cup of food at a time. By 12 to 18 months most people will manage about one cup of solid food. This is a guide only and will vary between people as there are different size sleeves.

A point relevant to all surgeries is that the people studied found they could indeed ‘fit’ more food in than what they felt satisfied with. After all forms of weight loss surgery, eating to the maximum amount you can tolerate is not recommended. I have a favourite quote from Dr. Teresa Girolamo, one of the GPs in our clinic: “It’s not a matter of seeing how much you can eat and get away with, but how little you can eat and be satisfied.” Testing the limits of how much you can eat increases your intake, particularly if it occurs repeatedly, and can compromise your results. Tune in to your feeling of satisfaction after eating and let that guide the amount of food you need to eat. Always stop eating before you feel any discomfort.

Create an environment that makes it easy for you to eat small portions. Ensure family and friends know you use a smaller plate/bowl/cutlery. Take these items with you if you travel. When eating out, order entrée size meals or if there are none available, separate your meal into an appropriate portion before you start eating. Tapas style menus, Asian or Indian eateries are often tailored to meals being shared, allowing you to dish up a small serve to suit your needs. It is fine to leave food on your plate when you have had enough, even if it is a smaller serve. Avoid the temptation to ‘clean the plate’. If ‘wasting’ food concerns you, carry a container with you when you eat out and take a serve home to have for another meal.

After gastric band surgery some people may find it takes some time before they feel satisfied on small amounts of food. Many people need their gastric band adjusted several times to help them feel satisfied on small serves. If small meals of solid food do not satisfy you, keep in regular contact with your support team until they do. Some people will find this will occur early in their journey, for others it may take longer. Be patient.

Whilst it is not necessary for you to measure or weigh everything you eat, it may be helpful to measure the amount you are usually serving. When you eat a meal, take note how much food it takes for you to feel satisfied and how much it takes to feel full. The aim is to feel satisfied after eating, so if you know roughly how much food this is you can avoid dishing up too much in future.

The recipes in my book and on my blog have been designed to provide approximately four, one cup serves. This does not mean a one cup serve is right for everyone, but does allows you to easily adapt the recipes to your requirements.

per my dr and nutitionist (with me having lap band/plication, 1 cup to 1 1/2 cup of food is my limit

my plication gives me that (full/had enough) feeling/sensation at about 1 cup...so i listen to my body.

i think it is important to stop even when (we easily) could eat more...

great article

I also think it depends on the surgery. It is my understanding that the sleeve and RNY give the most restriction, followed by DS and plication, then the band. I know that at 8 months post-sleeve, I can still only hold about 60 grams of dense Protein or 2/3 of a cup of less dense food. Knowing that, I don't dish out a cup because I know I can't eat it and it will just tempt me to try.

Also, full disclosure, I have (and love) your book. It is great to get Australia-specific advice, especially since our bariatric-products market is so immature.

I love the subject of food..My food intake varies..Im visual so all the cups, 1/2 cups, 1/3 cup mean nothing to me. All that measuring and counting became overwhelming to me. It became to stressful jut to enter the kitchen. I eat from a small salad plate. I visually fill it. I have learned the HARD HARD way how to fill my plate! I go over, and discomfort and pain will follow. Now, fruits and vegetables? I can eat way more than my salad plate, why? I chew them down to a pulp. One or two bites of mash potatoes (which I no longer eat) Im full to capacity, and discomfort ensues. So I choose to eat lots of fruits and veg & chicken.< /p>

I love this article. I am almost two years out and do feel like I was pushing my sleeve a little too much. I am going to watch closely how much food I placed on my plates.

      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.
