What Is The Liquid Diet Before Bariatric Surgery

The liquid diet before bariatric surgery is a liquid-only diet prescribed to patients two weeks before their scheduled surgery date. This diet involves 4 to 5 vitamin-fortified protein shakes every day without any food or additional calories. This diet is essential to maximize your surgical safety and healing following surgery. It also helps kick start weight loss, helps ensure success of the bariatric procedure, and can help patients develop an idea of what their weight loss journey will be like post-surgery.

National best practice guidelines have identified this liquid diet as a clear way to reduce the operative risk associated with large fatty livers. Many patients suffering from obesity develop fatty livers, meaning their liver enlarges due to fatty infiltration as theyve gained weight. Because the liver sits on top of the stomach, a large fatty infiltrated liver can make it much more difficult to access the stomach and introduce unnecessary risk.

The liquid diet is proven to help reduce the size of fatty livers before surgery, producing a much safer operative environment.

Blended Or Pureed Diet

Step 2 also lasts one to two weeks and includes blended or pureed food that is high in protein and low in fat . This includes:

  • Lean meats: Chicken, turkey, tuna, etc.
  • Soft foods: Scrambled eggs, cottage cheese, Greek yogurt, etc.

While the thought of eating blended or pureed food is hard for some people, patients have been on a liquid diet for so long by this point that theyre usually just happy to be getting solid food in their body, Lisa said.

Also, even though the liquid diet step is over, its still important for you to maintain the commitment to drink 64 ounces of fluids per day to avoid dehydration . This must be a lifelong commitment.

Dietary Guidelines Post Bariatric Surgery

Pin on after hospital stay

Bariatric surgery doesn’t eliminate dieting altogether. It means that if patients adhere to the prescribed diet for the rest of their lives, they’ll lose the excess weight and keep it off. On the contrary, if you ever go off the diet, you will gradually regain the weight lost.

Its important to start implementing this diet even before the surgery because pre-surgery weight-loss helps the surgeon by making the laparoscopic approach easier and safer and increases the likelihood that the surgery can be completed less invasively.

Other dietary requirements are basic common-sense eating. With sensible eating and exercise habits , the weight-loss can be easily maintained after surgery.

The long-term goal of weight-loss surgery is to lose approximately 55 to 75 percent of your excess weight. The end result of weight-loss surgery is that patients will continue to require only small portions of food and eventually be able to tolerate all types of foods. Patients bodies will be satisfied with smaller amounts of food and they wont have continued cravings for larger quantities of food at mealtimes.

How To Help Reduce Gas Pain After Gastric Bypass Surgery

Following your surgery you may suffer from gas pain. This is completely normal and you can treat it by using over the counter gas relief medication like Gas-X. However if youre not able to swallow or struggling another option you may want to try is peppermint tea.

Peppermint tea is a natural anti-inflammatory and can help relieve gas pain. You can also try drinking lemon or ginger tea as this will help reduce inflammation in your digestive system helping to speed up bariatric surgery recovery time!

In most cases you want to consume at least five bariatric full liquids a day which include water, coffee or tea with no added sugar, milk, bariatric milkshake or bariatric soup.

You may be feeling uncertain, maybe even a little concerned, but having a plan in place prior to surgery can help you feel calm and prepared. Your body will be in the early stages of healing, so full liquids will be gentle on your digestive system, but can still provide vital nutrients for healing.

Getting Nutrition From Liquids

A good way to make sure you drink enough is by taking small sips and making it a point not to gulp down your drinks. Its best if at least 1-1.5 litres of this comes from nutritious liquids every day, which will ensure that youre staying hydrated but wont cause any stomach stretching or discomfort later on in the process.

Week 1 Clear Liquids Only

3rd Full Day of Liquid Diet for Bariatric Sleeve Surgery.

In week one you are limited to clear liquids only. This sounds tough. And it is tough. However, most patients have very little desire to eat. The hunger hormone ghrelin is almost non-existent after surgery.

The part of the stomach that produces the majority of ghrelin is removed during surgery.

Make sure all items listed below are sugar free.

  • Water
  • Sugar free, nonfat ice cream
  • Thinned applesauce. Check sugar content.

Bariatric Liquid Diet Ideas: Protein Shakes

During your liquid diet phases, protein shakes are going to be your primary source of protein. You should try to consume 60 to 80 grams of protein per day, which usually equates to two protein shakes a day. You can use any protein shakes youd like, as long as the fat and sugar contents are under five grams each. Try to go for whey protein isolate as the source of protein in your protein shakes, as it gives you more protein with fewer carbohydrates, sugar and lactose. Some of my favorite protein shakes are Bariatric Advantage Iced Latte Flavor and RedCon1s Isotope Cake Batter Flavor.

Once you start the recovery process after bariatric surgery, bariatric liquid diet recipes will play a vital role in your journey.

Moreover, proteins need to be the most significant component of all these liquid diet recipes.

This liquid diet period will last for at least one week, and you need to drink at least 64 oz of fluid daily .

Additionally, you will be required to keep track of the daily protein intake during each of your meals.

Gather Or Buy Any Supplies Youll Need

Covered, insulated sipping cups will make it easier to keep sipping through the day. Choose a cup design that gives you joy and/or offers encouragement. Covered containers will be useful for storing pre-made protein shakes and sipping drinks. And a cooler with serving-size containers will make it easy to take your meals with you when you go out.

Reason #: Mental Awareness

After weight loss surgery you will continue the liquid diet. There will be some changes but for the most part, a liquid diet for 1-2 weeks after surgery is the standard of care. We want your staple lines and connections to heal well after surgery. You dont want to eat solid food right away and disrupt one of these connections. That could be detrimental to your outcome.

Your diet will be advanced slowly in a period of approximately 6 weeks. Please follow the guidelines given to you by your bariatric surgery program.

Doing the liquid diet before surgery will teach you what to eat after the surgery. Hopefully, you developed mental awareness about portions, calories, and ingredients in your diet.

One good news.

After surgery most likely you will not be hungry, so the liquid diet phase should be a lot easier.

You want to keep the mental awareness or your knowledge during the later stages of your diet after surgery. The new eating habits will help you to lose more weight but also and perhaps more importantly, keeping the weight off.

Approximately 25% of the patients that underwent bariatric surgery will regain some or all the weight back. This is mainly caused by a lack of Mental Awareness, lack of discipline or self-control. Bariatric surgery is only a tool to help you lose weight.

You need to make a commitment to the change. A lifestyle change.

Tips To Make The Liquid Diet Work

Between pre and post-surgery requirements, you will need to follow a liquid diet for 4 weeks or more. This will take some getting used to, but the following tips can help:

1. Read the nutrition facts label. The nutrition labels will help you estimate the total calories of your liquid diet and ensure you are meeting your protein needs, while avoiding too much sugar.

2. Space out meals and snacks. Eating everything at one time will make it harder to manage hunger throughout the day and will cause stomach problems after surgery.

3. Avoid restaurants. Very few things on the menu will be acceptable choices and it will only make it more difficult to stay on the diet.

4. Stick to a grocery list. It is much easier to have self-control once per week at the grocery store then to try to avoid tempting foods all week.

5. Focus on the big picture. Remember the reason you are choosing to undergo surgery and that liquid diets are ultimately temporary.

A Step In The Right Direction


Preparing for any kind of bariatric procedure involves a lot of information and personal preparation that can all feel very overwhelming. However, its important to keep in mind that rather this is a step in the right direction.

As restrictive as the liquid diet before surgery is, remember that this is you taking back control of your health and your life. After their operations most patients lose between 100-200 pounds of unhealthy body weight or more. Imagine how that would feel! Its time to start living the healthy energetic lifestyle you want, and the pre-op liquid diet before your surgery is the first step.
