Bariatric Liquid Diet Following Weight Loss Surgery

Following a post-op bariatric liquid diet gives you time to heal and make sure your body can tolerate taking in food by mouth. This diet is usually followed for the first week after your bariatric surgery procedure.

At first, take in liquids every six hours — about two ounces at a time. Gradually increase your intake of liquids to 6 to 8 ounces every hour. Drink very slowly and refrain from gulping.

Because this liquid diet does not contain a lot of nutrients, it is important to take your chewable multivitamins, calcium, B12 and iron supplements as directed.

Ideas for Bariatric Liquid Diet Recipes

  • Water: plain or flavored — non-carbonated, non-sparkling*
  • Clear, fat-free broths or bouillons**
  • Coffees and teas — caffeine-free, and no milk, cream or artificial creamers
  • Clear juices, including apple, cranberry, grape and orange juice — no pulp, and mix equal amounts of juice and water
  • Crystal Light or equivalent sugar-free, Kool-Aid type drinks
  • Sugar-free gelatin
  • Sugar-free popsicles

* You may drink regular tap water or drink any available bottled waters. There are flavored waters, such as Fruit2O, Propel and Fuze Slenderize, and water flavorings that are sugar-free and non-carbonated that have few to no calories. They are available at Wal-mart, Sam’s Club and other grocery or health food stores. Try to avoid sugary sports drinks as well.

** You can get broths and bouillons that are 99 percent fat free either already made in the can — i.e. Swanson, College Inn or store brand — or you can find them in cube or powdered form — i.e. Herb-ox, Wyler’s and Knorr.

Dr. Elías Ortiz, A Lighter Me’s chief of surgery, also recommends that you start slowly adding protein shakes when you return home, which is usually day six following the procedure.
