The Intra-Gastric Balloon (IGB), or the Gastric Balloon, is a non-surgical weight loss procedure that will make a patient feel full by restricting the stomach capacity similar to sleeve gastrectomy. However, instead of surgically removing a portion of the stomach, a large round object is used to specially fill gastric capacity. The gastric balloon weight loss system places a temporary balloon in the stomach and then inflated it with saline or gas endoscopically.

Gastric balloons work to reduce the available room in your stomach for food, causing you to eat less. The balloon also slows the passage of food and water in your stomach, causing you to feel full quicker and for a longer period of time. The post-op diet is the most effective component of long-term weight loss.

The balloon only remains within the stomach for 6 months (one year in the case of Spatz) and then it is removed. At that time the patient can decide if they are satisfied with the results or would like to proceed with a more aggressive surgery.

Gastric Balloon Diet

As with any weight loss procedure or regime, a proper diet is extremely important after the placement of the gastric balloon system to ensure success. Here we will go over the recommended gastric balloon diet, starting with the requirements immediately following the procedure, then transitioning to a healthy diet that can bring long-lasting results when adhered to.


  • Clear Liquids 48 hours prior to surgery (water, decaf tea, broth, sugar-free drinks, jello)
  • Nothing’s after midnight the night before your procedure

Important Note: For each phase of the diet, it is recommended you stay on for at least 3 – 5 days. Depending on your ability to transition to the next phase, the time may vary for each phase. You will want to make sure your body feels comfortable before moving to the next phase of the diet.

Gastric Balloon Post-Op Diet - Stage 1 Clear Liquids

Stage One: Clear Liquid Diet

For 3-5 days after placement, you will need to follow a clear liquid diet. The sole purpose of this phase is to stay hydrated. The hydration goal should be 64 oz or more, with a minimum of 48 oz to prevent dehydration. Try to stick with water, unsweetened decaf tea, or sugar-free beverages to avoid empty calories.

If consuming juice, it needs to be 100% fruit juice (no added sugar), and it needs to be diluted 50/50 with water to reduce sugar intake. If consuming a large amount of tea, alternate or stick with decaffeinated versions such as herbal teas to reduce the chance of dehydration. Tea is also acidic, so discontinue drinking if you experience heartburn or acid reflux.


  • 100% fruit juice (no added sugar) – clear juice (apple, white grape, cranberry) – dilute 50/50 with water
  • Broth (chicken, beef, and vegetarian)
  • No/low sugar coconut water
  • Crystal Light, vitamin zero water, Powerade Zero, propel, or other sugar-free flavored beverages
  • Unsweetened decaf tea
  • Sugar-free popsicles
  • Sugar-free gelatin
  • Water and/or ice chips

It is important to drink slow, small sips to avoid nausea. Start with½ ounce sips (1 Tablespoon), either using a measuring cup or the screw cap of a water bottle. Wait 60 seconds between each sip.

Avoid Caution AVOID:

Gastric Balloon Post-Op Diet - Stage 2 Thick Liquids

Stage Two: Thick Liquid Diet

In the following 3-5 days (after Stage 1) you can move on to Stage 2: Thick Liquid/Pureed Diet. During this stage of the gastric balloon diet, using a blender or food processor to puree your meals would be beneficial.

Aim for items that are high in nutrients and low in sugar.


  • Protein shake (pre-made or make your own using protein powder)
  • Greek yogurt (plain or Dannon Triple Zero)
  • Milk – Preferably Fairlife Milk but all types are acceptable (dairy, coconut, almond – unsweetened version)
  • V-8 Juice
  • Sugar-free pudding
  • Blended soups
  • No-sugar-added applesauce or other pureed fruits
  • Pureed vegetables

Avoid Caution AVOID:

  • Foods with large chunks or pieces
  • Foods with added sugar such as desserts
  • Carbonated Beverages

Gastric Balloon Post-Op Diet - Stage 3 Soft Solids

Stage Three: Semi-Solid Foods Diet

The next stage of the gastric balloon diet begins 7 to 10 days after balloon placement (following both stage 1 and stage 2 post-op diet plan). At this time, you can start stage 3: semi-solid foods.

The foods for phase three should encompass items that are mainly soft, moist, and can be easily mashed with a fork.


  • Cottage cheese
  • Beans
  • Ricotta cheese
  • String cheese
  • Soft fish
  • Canned chicken, tuna, or salmon mixed with a little mayo
  • Meat cooked in a crock-pot until tender.
  • Well-cooked or mashed vegetables (squash, sweet potato, green beans, etc.)
  • Avocado
  • Scrambled eggs
  • Crab
  • Deli meat
  • Tofu

Gastric Balloon Post-Op Diet - Stage 4 Solid Foods

Stage Four: Solid Foods Diet

When you are ready, you can transition to stage 4 of the gastric balloon diet, solid foods. This is where you can start eating normal foods again and adding a healthy variety back into your diet plan.

This is also when it is most important to create a balanced, healthy diet and healthy habits that will set the stage for your long-term success.

Healthy Gastric Balloon Diet Guidelines (Stage 4 and Long-Term)

  • Calories: 1000 – 1200
  • Protein: 75 – 105g
  • Carbohydrates: less than 75g (25 – 50g for quicker results)
  • Fat: 40 – 50g
  • Sugar: <25 g

Sample Diet Plan (Meal Plan)

  • Breakfast: Protein shake, up to ½ banana (optional)
  • Snack 1: Cheese stick
  • Lunch: 3 oz chicken, ¼ avocado, 2 oz cooked vegetables, beans, or whole grain
  • Snack 2: 15 Almonds
  • Dinner: 3 oz salmon, 2 oz non-starchy vegetables, 1 TB oil or butter
  • Snack 3: Triple Zero Greek yogurt, ¼ cup berries

Focus your diet mostly on lean protein and non-starchy vegetables. Fat is also a healthy addition but needs to be monitored, as too much can negatively impact weight loss. Fruit, whole grain, and beans are also healthy additions to a diet but should be eaten in moderation and should always be paired with protein if possible.

Healthy Habits to Help Succeed Long-Term

  • Eat small meals/snacks 5 times a day
  • 3 small meals and 2 healthy snacks
  • One protein shake a day (counts as a snack or meal)
  • Always pair fruit or grain with protein, such as greek yogurt or cracker with cheese. Focus mostly on protein.
  • Eat something every 2-3 hours
  • Drink a minimum of 64 oz of water
  • Avoid sweets and processed foods
  • Avoid “doughy” foods (they may stick to balloons and cause bad breath)
  • Take a good quality multivitamin every day (no gummies, which contain sugar)
  • Track food intake in a food journal or mobile app
  • Limit consumption of alcohol

Gastric Balloon Exercise

Boot Camp - Diet and Exercise

Exercise will help you burn calories and build muscle, which will help you lose weight quicker. Starting a regular exercise schedule as soon as a week after the procedure is highly recommended.

A good goal for exercise is 30 minutes at 5x a week. We recommend that you start slow with walking and slowly increase in exercise.

It is extremely important to continue this exercise regimen after the gastric balloon is removed to prevent the chance that you will regain the lost weight.

Discomfort and Nausea

After placing the intragastric balloon, most patients will experience gastric discomfort for the first week after the procedure: cramping, nausea, and vomiting. This is normal, as your digestive system is adjusting to the presence of the intragastric balloon.

The discomfort will rarely continue in the long term. You will be given medications to help you manage these symptoms. Please use these anti-nausea medications as prescribed.

Helpful Tips to Prevent Discomfort and Nausea

  • Watch your posture during meals and while drinking fluids. Sit tall and do not slouch. This will help your balloon position properly and increase your tolerance for foods.
  • Eat slowly and chew your food well before swallowing.
  • Stop eating if you feel heartburn (acid reflux).
  • No liquids 30 minutes before your meal and wait 30 minutes after to drink.
  • Stop eating when you feel full or satisfied.
  • No food 3 hours prior to bedtime
  • Some discomfort may occur while trying to sleep; you may need to prop yourself up with a pillow.
