What to Eat After Gastric Bypass Surgery

Congratulations on starting your weight loss journey! Metabolic and bariatric surgery is a life-changing procedure that can help to support weight loss and offer you a better quality of life. 

After surgery, you will undergo a series of diet stages. They will differ in length based on the surgery performed and your tolerance to new foods. 

The Importance Of Proteins

This new staple diet is a protein-centered phased approach diet plan. Why? Proteins are the building blocks of all life. All human cells contain protein.* 

Proteins aid in repairing and restoring tissue, catalyzing the healing of your new stomach pouch, and supporting muscle maintenance.*

If there are insufficient protein stores, you will feel fatigued, with decreased metabolism, and unhealthy weight fluctuations.* 

Protein drinks for bariatric patients are a great investment for your health after surgery. They are a great vehicle for getting your protein-packed nourishment. Gastric bypass and Gastric sleeve protein shake recipes have yummy and nutrient-dense ingredients to sustain you. We list some recipe options below!

Another great investment is a gastric bypass cookbook. This is a very beneficial tool as the bariatric diet will be your lifelong staple. It outlines the bariatric food pyramid with proteins being the prioritized food group.

Clear Liquid Diet 

Stage 1: 1-2  Days Post-op

Phase 1 post-op is typically a clear liquid diet. This will only include clear liquids that are sugar-free. Depending on the individual, this phase should only last about 1-2 days after surgery. The purpose of this phase 1 diet will be to allow the stomach to heal while still ensuring the body is receiving fluids and electrolytes. 

Hydration is Essential

Dehydration has become a common occurrence after metabolic and bariatric surgery, resulting in readmission to the hospital within 30 days after surgery. (2)* 

A goal during your diet phase 1 post-op is to consume at least 48-64oz of fluids daily. In order to combat the difficulty of drinking fluids after surgery, try drinking from a small cup and taking small sips throughout the entire day. Aim for at least 1-3oz of fluids consumed every 30 minutes. 

Bariatric Supplements

Post-bariatric vitamins are always recommended and should be taken as directed. A chewable supplement form is typically recommended initially following surgery to support healing and toleration.* 

Some healthcare providers will recommend starting bariatric supplements before surgery and continuing after, while others will recommend starting them in the hospital after surgery. Always follow the recommendations of your healthcare provider and dietitian following weight loss surgery

There are different multivitamin options available, such as a bariatric multivitamin with iron or an all-inclusive multivitamin chewable

Clear Liquid Options

Clear liquids apply to fluids that you can see through. This can include the following:

  • Water, flavored water
  • Crystal Light
  • Propel
  • G2 Gatorade
  • Sugar-free KoolAid
  • Sugar-free popsicles
  • Sugar-free Jell-O
  • Chicken, Beef, or Bone broth
  • Ocean Spray sugar-free drink mixes

Your after gastric bypass surgery diet plan will progress when medically feasible and cleared by your healthcare provider. This will start to include protein shakes. Protein shakes and bariatric surgery are important when not enough protein can be consumed through dietary food sources. Over time, you can expand to include more recipes for after gastric bypass surgery. Small portions, specific ingredients, and limitations of certain processed foods must be maintained to ensure adequate health and to support a healthy weight.*

At this point, your diet may fall into the 1000-calorie bariatric diet plan. If you find you are exceeding this goal, look into purchasing a bariatric portion plate to assist with moderation and portion control

You will find that you are able to explore more dietary options, but may require alternatives to typical recipes. This would include if you are a fan of sushi. Sushi after gastric bypass will require some alternatives including being made without rice. 

It doesn’t matter whether you are eating 2 months after your procedure or eating 6 months after gastric bypass, it still calls for a low-calorie, high-protein diet. This supports healthy weight in the long-term.*

Gastric Bypass Information

There are a number of new recommendations you will have to follow in order to see the best outcomes from having surgery.

Gastric bypass and alcohol are one of the limitations that are highlighted after surgery. Alcohol typically is not allowed after surgery unless otherwise stated by your healthcare provider. Alcohol contains empty calories, and your body processes it differently after surgery.  

Alcohol can also create fluctuations in blood sugar. Low blood sugar after gastric bypass surgery can be a risk and should be monitored. 

Caffeine is another hot topic after surgery. Why no caffeine after gastric bypass? Large amounts can be a diuretic. Caffeine is also very acidic and may not be tolerated well with your new stomach pouch.  

Carbonation after gastric sleeve is also not recommended. Carbonation can cause bloating and a false sense of fullness in your new stomach pouch.

Also, stay away from controversial topics like diet pills after gastric sleeve or gastric bypass unless you have consulted a qualified healthcare provider. This topic remains controversial, lacking sufficient evidence of its effectiveness. 

Another thing to remember is to stay away from fad diets after surgery. Fad diets are restrictive, lack major nutrients, and lack sustainability. A keto diet gastric bypass would fall under this category, despite giving short-term results. Long-term outcomes are unlikely. (1)*

Food Guidelines for Bariatric Surgery

What to eat before gastric sleeve surgery and gastric bypass? A protein-enriched diet, and then you’ll be gradually instructed to follow an approved clear liquid diet. The clear liquid diet before gastric sleeve will help to cleanse your system for your operation and support your weight loss. A very similar diet is started directly following surgery as well. 

When it comes to eating after metabolic and bariatric surgery, when the time is appropriate, eating out after gastric bypass shouldn’t be a burden. The best restaurants for bariatric patients offer great-tasting, healthy meals at affordable prices. 

However, creating meals on your own is always a great option when it comes to your health and wellness. You could create a recipe for bariatric cheeseburger pie or even bariatric pancakes that are low in calories.

Meal plans for gastric sleeve patients and patients with gastric bypass consist of high protein (eg. fish, turkey, tofu) to aid your recovery post-op.*


Gastric bypass surgery is malabsorptive and restrictive, limiting the number of nutrients you can consume and also your ability to absorb them.

Nutrition is imperative for healthy living, especially post gastric bypass. You need all the nourishment you can get. This includes taking your daily bariatric multivitamin to avoid common deficiencies.* 

The recipes we have provided above are just a few of the many options you have following surgery. Support a healthy lifestyle by eating the right food for the right stage of your journey through metabolic and bariatric surgery
