After bariatric surgery, it is important to follow a specific dietary plan to promote weight loss and prevent complications. The dietary guidelines may vary depending on the type of surgery and the individual’s specific needs, but generally, the following guidelines apply:

Start with clear liquids: In the immediate postoperative period, patients will be limited to clear liquids, such as water, broth, and sugar-free gelatin.

Follow a progression to pureed foods: After a few days, patients can start to introduce pureed foods, such as mashed potatoes, scrambled eggs, and cottage cheese.

Incorporate soft foods: Over time, patients can add soft foods, such as canned fruit, cooked vegetables, and tender meats.

void high-fat, high-sugar foods: Patients should avoid foods that are high in fat and sugar, as these can lead to dumping syndrome, a condition in which food moves too quickly through the stomach and causes nausea, vomiting, and diarrhea.

Eat small, frequent meals: Patients should eat small, frequent meals throughout the day to help maintain blood sugar levels and prevent overeating.

Chew food thoroughly: Patients should chew food thoroughly and eat slowly to prevent nausea, vomiting, and discomfort.

Stay hydrated: It is important to drink plenty of water throughout the day to prevent dehydration and promote healthy digestion.

It is also important to work with a healthcare professional and a registered dietitian to develop a personalized dietary plan after bariatric surgery. They can provide guidance on portion sizes, nutrient needs, and meal planning to ensure long-term success and health.


  • Always eat balanced diet
  • Always eat small portions and frequently
  • Do not skip food for more than 3 hours
  • STOP  eating if you feel pain, fullness, discomfort, nausea, or vomiting. Occasional vomiting is common and food intolerances vary on an individual basis.  If a food is not tolerated, do not force yourself.

  • Eat slowly and chew at least 20 times before you swallow.
  • Do not use straw, drink carbonated beverages, it might introduce air into you newly created pouch and cause abdominal pain or discomfort.
  • Always SAY NO to sugar, sugar containing foods, carbonated beverages, deep fried food, concentrated sweets and fruit juice.
  • For the first months of surgery , your calories intake should be between 300 to 600 calories per day, after that calories intake should be between 800 to 1200 calories

Fluid And Liquid Diet

  • Always hydrate yourself
  • Take at least 2 litre of fluid per day
  • Avoid carbonated and sweet and caffeine from your liquid
  • To not take liquid with food
  • Always carry your liquid diet with you
  • Take fluid between 2 small meals.
  • Try to avoid alcohol

Protein Intake

  • After surgery your intake would be low, which may result in decreased muscle mass in your body.
  • To avoid these consequences eat foods rich in high protein .
  • High-protein foods include poultry, soy milk, tofu, cottage cheese, yogurt and other milk product, eggs and meats.
  • Minimum intake of protein should be 65 to 75 grams per day. Don’t worry if you are unable to reach your goal for first few months after surgery.

Minerals And Vitamins Supplements

  • You may need to take the mineral and vitamins supplements as prescribed by your Doctor to prevent nutrient deficiency.
  • Nutrient supplements may include Calcium, Vitamin D, Vitamin B12, Selenium, Folic Acid, Iron, copper, zinc etc.


All pills prescribed by your Doctor must be crushed into smaller pieces because it can be difficult for the pills to pass through the new anatomy.
