It is strongly suggested that all post-op patients make monthly appointments with Sharon or Rachel after surgery. These appointments allow you to review any food problems you may be having, make sure you are getting enough protein, get answers to any diet-related questions, advance your diet properly, and plan your daily food regimen. The postoperative diet is divided into 3 stages with specific timelines and guidelines for each to allow gradual adjustment to your new stomach after surgery:

Stage I: Bariatric Liquid Diet

Patients will be on the stage I diet in the hospital and some will remain on the diet after surgery, as per their surgeon. This stage includes low-sugar, non-carbonated liquids.

  • You will be brought a tray with water, tea, broth, and/or sugar-free Gatorade.
  • Low-sugar, non-carbonated drinks include Crystal Light, Diet Snapple, & Vitamin Water Zero.
  • Sugar-free Jell-O and popsicles are also allowed.
  • Drink 3 NYBG protein drinks a day (about 15-20 grams of protein each) to reach the goal of 60 grams of protein.
  • Use a cup to drink. Avoid sipping from the bottle or using straws – this can make you swallow too much air and cause gas.

Stage II: Bariatric Soft, Mushy Pureed Diet. First Month After Surgery.

Stage II of your post-bariatric surgery diet, soft foods from the list below can now gradually be added. Be sure to continue following all of our additional instructions and guidelines for your bariatric surgery diet to ensure a smooth and comfortable experience and recovery process.

3 meals per day with 2 NYBG protein shakes or supplements containing 15-20 grams of protein each between meals.

Stage II Foods

  • Skim or 1% milk, low fat cottage cheese, low-fat plain yogurt, low-fat ricotta cheese
  • Chicken, vegetable, or beef broth (without noodles, vegetables, or chunks)
  • Ground meat and poultry like turkey, chicken, veal, or pork
  • Eggs or egg whites, in all forms, as long as they are not dried out, and can be mashed with a fork
  • White flakey fish, like tilapia, cod, or flounder
  • Pureed chicken and vegetable soup, especially if experiencing constipation
  • Sugar-free popsicles, jello, puddings or fudgesicles

Be Sure to Avoid

  • Carbonated drinks – these will stretch your stomach and give you gas pains!
  • Creamy soups – these are high in fat and calories!
  • Reheating foods in the microwave – the microwave will alter the consistency of food

Important Points

  • Chew well, eat food slowly.
  • Make sure protein is moist and in small pieces.
  • No eating and drinking at the same time. Drink your fluids between meals and up until the meal. Wait 30 minutes after the meal to resume drinking.

Vitamins and Minerals

  • Multivitamin: Take 1 chewable vitamin (e.g. NYBG.) daily. These are best taken with food.
  • Calcium: Take our recommended Calcium Citrate Lozenges four times a day, 1 with breakfast, lunch, snack and dinner.
