Pre-Surgery and Post Gastric Sleeve Surgery Nutrition: How Will Bariatric Procedures Affect Your Diet?
We have erratic meal times, readily available junk food and superbly busy lives. Hence, for many of us, it’s increasingly harder to lose weight OR keep lost kilos from coming back.
To make matters worse, weight gain often SNEAKS UP on us. Many of us don’t even realise we are putting lots of weight on until quite late in the ‘gaining cycle.’
So if you’ve had weight loss surgery, or are about to have it, what changes do you need to make in your daily eating plans to optimise your results?
In this blog, we discuss the pre-gastric sleeve and post-gastric sleeve diet.
Here’s an overview of what’s considered one of the best diets to follow after having weight loss surgery.
Are you struggling to lose weight to improve your health?
If you’re on the high BMI scale of obesity, you may end up researching your weight loss surgery options.
- When nothing in our beloved wardrobe fits anymore, including our stretchiest slacks or leggins – a near panic can even set in.
- Wanting or needing to reduce excess weight quickly goes through our minds.
- IF not OUR minds, then the minds of our General Practitioners or Endocrinologist, who tend to like to remind us of the detrimental health repercussions of being overweight.
- It’s then that some of us struggling with a high BMI or obesity level weight problems consider weight loss surgery, medically called Bariatric Surgery.
We are bombarded by junk food options and fast food chains.
How are we ever going to keep our weight in check, even following the best eating plans after having weight loss surgery?
Pre and Post Gastric Sleeve Diet and Eating after Weight Loss Surgery
- Whether you choose a gastric sleeve, a gastric band or lapband, a gastric bypass or other weight loss surgery procedure, you’ll need to make changes in how you eat
- These diet changes are required both BEFORE and AFTER you have the gastric procedure performed (pre and post-gastric sleeve diets)
- And whatever surgery you choose, if you lose over 20 kilos of weight, you are likely going to need excess skin excisions and body contouring surgery to help reduce skin fold problems associated with sagging skin after losing a lot of weight.

Why is obesity such an issue in today’s communities – and what diets are best to overcome obesity level weight concerns?
- With busy lives, sugar-laden drinks and fast-food availability
- There are also “bulk buy” food stores and a lack of outdoor activity because we’re obsessed with Netflix watching, computer games and/or social media
- These factors and other lifestyle and meal habit changes have led to national epidemic of OBESITY in Australia
Unfortunately, it’s not as easy to lose weight as it is to gain weight.
Our currently lifestyles aren’t exactly helping.
Once we get to a certain super-sized, unhealthy Body Mass Index (BMI), we can also find that our joints don’t safely allow our bodies to exercise without pain or risk to our ligaments and joints.
- It’s then that it might become time to consider your options for medical intervention into the state of your weight.
- And we find a holistic approach works best; although part of the solution might be researching gastric bypass, gastric sleeve or other weight loss surgery procedures.
Some People Cannot Lose Enough Weight without Bariatric Surgical Intervention
- Some people really struggle to lose weight
- It can be especially difficult to change your BMI after becoming severely overweight, to the point of being classified as being obese or morbidly obese (which means having a BMI of over 29.9 or 30).
- Being OBESE makes it difficult to exercise and you’ll tend to feel lethargic or have sore joints (knees, hips, shoulders and elbows)
Despite exercising and eating as healthily as they can – no amount of dieting seems to help some individuals lose weight.
In these cases, they may need BARIATRIC surgery or Gastric Sleeve Weight Loss Surgery.
- The reasons for difficulty with weight management are often multi-faceted.
- Reasons can include metabolic or hormonal changes, thyroid problems and even brain chemistry that fails to register ‘fullness’ after eating.
- Bariatric Gastric Surgery – and making nutritional and dietary changes BEFORE and AFTER weight loss surgery – may be the best option for some individuals who’ve been unable to reduce obesity levels by any other measures.
Before we overview the Pre-Surgery and Post-Weight Loss Surgery diet, let’s talk about how nutritional choices and body weight interact.
Genetics, brain chemistry and lifestyle choices are all often intertwined in the occurrence of obesity.
- People who are obese have likely gotten to the point that their stomach has the capacity – and the emotional drivers – to consume far more calories than they could ever hope to burn off – no matter how much they exercised.
- It’s part genetic, and sometimes related to medication side effects or an inability to exercise.
- But research does show that obesity primarily relates to dietary intake; and that living a healthier lifestyle can go a long way to reducing excess body fat.
We all know that living with obesity is dangerous to health and longevity.
- Too often, people resort to the latest fad diet or crash diet when they get fed up with being overweight.
- This can help, temporarily, but is often non-sustainable in the longer term.
- That’s because we recognise that imbalanced eating regimes and crash diets can have highly adverse impacts on our health.
Are fad diets dangerous?
These extreme diets can be very taxing to your organs and other body systems.
- Extreme diet regimes are also unlikely to help keep the weight off over time.
- In fact, diets often lead to further weight gain once you go back to eating normally or eating as you did before.
Weight, Waistline & BMI factor into Obesity Health Problems
In such a scenario where your weight, your waistline and your BMI are at dangerously high levels in relation to your overall health – your GP may recommend a weight loss surgery such as a Gastric Sleeve, Gastric Band Surgery, Gastric Bypass or a Lap Band surgery procedure.
What is Gastric Sleeve Surgery?
- A gastric sleeve surgery involves reducing the size of the stomach, which in turn helps patients to lose weight by limiting how much food they can comfortably or safely consume.
- Once the size of the stomach is reduced, a person’s appetite is also impacted and they feel hungry less often.
- A person with a reduced stomach size also has the sensation of becoming fuller, faster, which also helps to reduce food intake and excessive calorie consumption.
Gastric Sleeve Surgery is gaining more popularity since it has a much shorter operating time than the gastric bypass or lap band surgery, but is effective at helping people lose weight to overcome obesity.
Unlike the lap band, no adjustments are needed with a Gastric Sleeve Procedure.
Plus, it appears that surgery patients are able to lose more weight with a Gastric Sleeve procedure compared to a Lap Band or a Gastric Bypass.

Gastric Sleeve Diet Before Your Surgery (Liver Health)
- If you choose to have this Gastric Sleeve surgery, your Specialist Bariatric Surgeon (Obesity Surgery Specialist) will give you specific pre-surgery and post-op diet details.
- They’ll also advise you of the potential complications and surgical risks of gastric surgery to overcome obesity and help you lose weight.
If you’re very overweight or obese, you suffer from Non-Alcoholic Fatty Liver Disease.
- In general, several weeks prior to your surgery (at least 4 weeks before your surgery date), you’ll likely be advised to undertake a special diet to help shrink the size of your liver.
- An enlarged or ‘fatty’ liver can impact your Surgeon’s access during your Bariatric operation.
- A fatty liver also increases the risk of having serious complications from surgery, so you’ll need to be diligent in following your pre-op nutrition instructions and follow the prescribed liver-reducing diet (click here for an example).
Eating differently BEFORE your Gastric Sleeve Surgery not only helps to leave you healthier, it also helps you prepare for an altered diet that you will need to adhere to AFTER your gastric surgery procedure.
- In your pre-surgery eating plan, you’ll likely be told to consume a bit more protein and less carbohydrates than your normal eating regime.
- You may also be asked to eliminate added sugars and avoid soft drinks (this can also help you lose weight as soft drinks are a contributing factor to rising sugar intake and higher obesity rates).
- You must also drink lots of fluids or liquids to stay well hydrated (water is typically best)
- Be careful that your higher liquid intake doesn’t include hidden sugars.
- Your Gastric Sleeve Surgeon may also advise you to undergo a strictly liquid diet two days prior to the surgical day.
- Your Bariatric Surgeon and Care Team will likely give you specific instructions for the months, weeks and days before your surgery.
- Preparations and planning for bariatric surgery can take more time than you realise
- So if you’re considering this option, be sure to book a consultation with your chosen Bariatric Surgeon as soon as you know you’re wanting the surgery to best prepare yourself for a Gastric Sleeve.
Nutritional Changes after Gastric Sleeve Surgery
In the days, months and years following your gastric sleeve surgery, you’ll need to take utmost care of your nutritional intake and eating routines.
Week One after Gastric Sleeve – What Might Be Typical (but ASK your Surgeon as this may not apply to you).
The information below is of a general nature and is not intended as advice. It is also NOT a substitute for the medical information and pre and post-op recommendations provided to you by your GP and your Gastric Surgeon or other health professionals assisting you with your medical care. It is intended only as an information starting point for discussions with your Surgeon about how you’ll need to adapt your eating plan after Surgery. Every patient, every procedure and every Bariatric Surgeon and Nutritional Team has a unique approach – so follow your Specialist’s instructions.
In general, here is the general eating advice given to patients who are about to have Gastric Sleeve operations – but YOUR post-weight loss diet instructions could VARY.
So ask your Doctor or Surgeon for specific post-op care to suit your specific health needs.
Week One after Weight Loss Surgery: What You Might Be able to Consume After Gastric Sleeve Surgery during the First Week After Having Surgery
Week 1: Clear Liquids Only
- In the first week after your gastric sleeve surgery, you may be allowed to take in ONLY clear liquids such as water, fresh juices, soups and broths.
- Typically, you’ll also be told to take small sips to take in these liquids very slowly.
- Decaffeinated tea and coffee are usually okay a few days after your Surgery
- However, you’ll need to check this with your Surgeon
- They might NOT be permitted for you in relation to your health or specific procedure.
- You should, however, avoid ALL carbonated beverages and drinks with added sugars.
- If you’re readily able to tolerate liquids, then your Surgeon will advise you when you can advance to the next stage of eating changes.
Week Two After Gastric Sleeve Surgery: Pureed Foods
- During the second week, you may typically take in foods in their pureed form.
- These may include mashed potatoes, low-fat cottage cheese, sugar-free yogurt, soup with blenderised vegetables and hot watery oatmeal.
- You might be tempted to overdo it – but don’t. It’s not worth the risk and can get very uncomfortable very quickly if you eat the wrong foods, or too much of the right ones, after surgery.
Week Three After Gastric Sleeve Surgery: Protein Shakes and Soft Foods
- In the third week, you might be able take protein shakes about once a day, but ask your Surgeon to be certain.
- You might also be approved to eat hummus, steamed or boiled vegetables, soft cereals, scrambled eggs, mashed fruits, steamed fish, ground chicken with stock and soups.
Foods to avoid just after having Weight Loss Surgery:
- Starchy foods like rice, pasta and bread need to be avoided.
- Fibrous vegetables like broccoli, celery and asparagus should also be avoided as they are difficult to digest.
Week Four After Gastric Sleeve Surgery: Some Solid Meals
People ask when they will be able to eat solid foods or real meals after having weight loss surgery. The amounts will be forever changed, as you won’t be able to consume the portion sizes you once did. But in the 4th week after weight loss surgery or a gastric sleeve, you will be able to start eating some small portions of the following solid foods.
In the fourth week, your eating regime may be permitted to include some ‘solid’ meals.
- You can typically start eating some fruits, sweet potatoes, baked potatoes, cereals, fish and chicken four weeks after having weight loss surgery.
- Avoid eating fried foods, desserts, lollies, whole milk and nuts as these are very difficult to digest.
- During the next week (Week 5), you can typically have one or two healthy snacks in-between your meal times.
- A hard-boiled egg, a banana or hummus with soft rice crackers might be good options, but be sure you check with your Surgeon and Nutritionist.
- The most important thing that needs to be kept in mind is that your meals should have high nutritional value (e.g., be nutrient-dense) as well as remain sparse in calories.
In the subsequent weeks and months AFTER your weight loss surgery, you’ll also have specific eating recommendations from your Surgical team, and you’ll need to monitor your eating regime and portion control.
How Long Before I see Weight Reduction after Gastric Sleeve Surgery?
It is often noted that patients can start seeing weight change results just weeks after their gastric surgery procedures. On average, with Bariatric Surgery, you can anticipate losing around 60% of your pre-surgery weight.
What about my skin after Gastric Band or Gastric Sleeve procedures?
Will I end up with skin folds and skin infections after having weight loss surgery?
Some patients get skin folds, others do not. It is quite common and some Australian Bariatric Surgeons don’t discuss this with patients in enough detail; so patients are dismayed by their body shape after losing weight – mostly relating to excess folds of skin.
- Gastric sleeve surgery and other weight loss procedures can leave you with ‘saggy’ baggy skin.
- Medically, the post-weight loss skin (rolls or sagging skin) is called Redundant Skin and it typically needs to be surgically reduced (excised, usually along with liposuction).
Sadly, you can’t exercise away skin folds after losing weight.
And excess skin, along with stubborn fat stores even after significant weight loss, means you’ll end up needing more surgery to get the body contours you are wanting after working so hard to get a healthier, more natural body shape after obesity.
If you need your redundant skin reduced to return smoother body contours, our leading Plastic Surgeons including Dr Richard Maxwell and Dr Geoff Barnett (Post Massive Weight Loss Body Contouring Surgeons) offer many various Body Contouring procedures. The most common cosmetic surgeries or plastic surgeries after significant weight loss occurs include:
- Tummy Tuck/Abdominoplasty procedures
- Belt Lipectomy surgery (more common for formerly obese patients than a traditional Tummy Tuck)
- Upper Arm Reduction/Arm Lift
- Thigh Reduction
- Breast Reduction
- Breast Lift Surgery
- Breast Lift Surgery with Implants
- Face Lift
There is a sequence that you might want to ask your Surgeon about, and many people do Upper Body Lift procedures and Lower Body Lift procedures in stages. You might want to start with the surgery to reduce redundant skin in the area that troubles you the most (such as a thigh reduction or belt lipectomy or upper arm reduction surgery known as a Brachioplasty).
If after you have adopted your new healthy lifestyle and done everything you can to see changes in your weight, and are still not completely happy with the outcome after approximately 18 months to up to 4 years, you might also want to consider Liposuction and Body Contouring with one of our Specialist Plastic Surgeons.
Melbourne Plastic Surgeon, Dr Geoff Barnett (FRACS) and colleagues Dr Richard Maxwell (Melbourne VIC) and Dr Richard Sackelariou (Sydney NSW) and are our Group’s top body contouring specialists for post-bariatric surgery patients. Dr Barnett and his colleagues are Specialist Plastic Surgeons who focus on patients who have lost massive amounts of weight either using bariatric surgery methods such as Gastric Sleeve Surgery or Gastric Banding.
They help individuals who have lost weight on their own through major lifestyle changes (but not everyone has success overcoming obesity without surgery), including offering Face Lifts, Tummy Tuck/Abdominoplasty procedures, Breast Lifts, Breast Reductions and Arm Reductions/Thigh Reductions as well as Belt Lipectomy (Circumferential Abdominoplasty) procedures.
