Stages of the Post Bariatric Surgery Diet: A Step-by-Step Breakdown

A staged approach is usually followed in a gastric bypass diet to gradually reintroduce solid foods and facilitate a smooth transition. The pace at which you progress from one stage to another is determined by the rate at which your body heals and adapts to the new eating patterns.

Stage 1: Liquid Diet

  • An all-liquid diet will be needed immediately after surgery to ensure healing and hydration. It is important to follow the nutrition guidelines very closely to prevent serious complications.
  • Stage 1 includes: clear liquids such as broth, flavoured waters, sugar-free popsicles, unsweetened juice, decaffeinated tea or coffee, milk and protein shakes.

Stage 2: Puréed Diet

  • 1-2 weeks after surgery, the bariatric dietitian helps patients transition to puréed foods. Intake will be small at first, about 1-2 ounces 3 to 4 times per day.
  • Pureed foods includes: puréed fruits and vegetables, pureed meats, yogurt, smooth soups, and sugar-free pudding.
  • Protein intake should be the focus. Protein shakes will still be needed to meet daily protein goals.

Stage 3: Soft Foods Diet

  • Soft foods are introduced 4 weeks after surgery. Patients are encouraged to try one new food at a time, chew very well and eat slowly. Foods and liquids should be separated - not drinking liquids until 30 minutes after finishing a meal. Meals are no more than ¼ to ½ cup in size.
  • Stage 3 foods include well-cooked vegetables, tender meats (dark meat chicken, canned tuna or chicken, deli meats), soft fruits, cheese, and nut butters.

  • Stage 4 begins 6 weeks after surgery and continues for a lifetime. The focus is finding balance in all food groups: proteins, whole grains, fruits, vegetables and healthy fats.
  • Total meal size after bariatric surgery is ½ to 1 cup, depending on the type of surgery and texture of the foods being eaten.
