Diet & Life After

You did it. Your weight loss surgery is finished. But your new journey has just begun. Make sure you follow these post-operative diet restrictions and consult your bariatric team nutritionist with any questions about food, intake and overall nutritional value. To start, it’s all about liquids and proteins.

Phase 1: Liquid Stage

Day 0 – 14 (Post-Surgery)


Stay hydrated and don’t worry about calories. Drink as much as your body tolerates. This amount will increase every day.


  • Drink clear liquids — For the first week drink clear liquids then gradually add milk- based products to your diet.
  • Drink liquids slowly — Take a few sips, then wait 1-2 minutes for your stomach to feel empty.
  • Drink protein shakes — At least one protein shake each day.
  • Eat low fat options — Soup, skim milk, diluted cream of wheat, cream of rice cereal, sugar-free pudding, sugar-free jello and popsicles.
  • Drink calorie-free beverages — Between meals drink water, Crystal-Lite, Diet Snapple or Propel (no carbonated drinks).
  • Drink 64 oz. of liquid each day — You’ll get there after a few weeks.
  • Take your vitamins — Eat chewable vitamin mineral supplements one week after surgery.

Phase 2: Pureed Stage

Week 3–4 (Post-Surgery)


Stay hydrated and improve your protein intake.


  • Drink 64 oz. of liquid each day — You’ve got this!
  • Take your vitamins — Eat chewable vitamin mineral supplements one week after surgery.
  • Drink protein shakes — Drink 3 protein shake each day.
  • Eat high protein items first at meals — Include cottage cheese, low-fat soups, and light yogurt in your diet. Then add pureed chicken, turkey, fish and eggs (baby food consistency).
  • Eat vegetables — Puree or ground up your vegetables.
  • Include starches —Choose cooked cereals, pasta, sweet potatoes or mashed potatoes.
  • Snack on fruit —Include mashed or pureed canned fruits with light syrup. No fresh fruits allowed.
  • Calculate your protein — Get a minimum of 50-70 grams of protein per day.

Phase 3: Back to Normal

Moving Forward Post-Surgery


A return to normal consistency foods, eat when you’re hungry and stop when you’re full.

  • Eat slowly — You won’t be able to eat red meat or bread immediately, so ease into them. Trial and error is key to getting to an unrestricted diet.
  • Eat when you’re hungry — Be sure to eat 2-3 small, high-in-protein meals each day.
  • Drink calorie-free beverages — Drink at least 2 quarts in between meals each day, to lower your risk for developing kidney stones. Stay away from carbonated beverages.
  • Avoid simple sugars — No cookies, cakes, pies or candy. Only eat bread in small quantities.
  • Eat slowly — Chew well and drink plenty of liquids.
Vitamins and Minerals
  • Vitamins and mineral supplements are mandatory now, for life.
  • Calcium — 500mg of Tums three times a day.
  • Multivitamin— Two multivitamins a day, including chewable or liquid adult multivitamins.
  • Iron— Ferrous Sulfate and Ferrous Gluconate required in pre-menopausal women once a day.
