You’ll be limited to consuming a clear liquid diet to allow your new stomach pouch to heal properly during the first 1 to 2 weeks following surgery. Any food or drink that is transparent and does not need to be chewed falls into the clear-liquids category.

Clear Liquid Diet after bariatric surgery

Here are the general guidelines for the clear liquid diet stage:

  • Meal size: 1 to 2 ounces
  • Meal frequency: 3 to 5 times per day
  • Fluid intake: 64 fluid ounces per day

You’ll need to give yourself at least 5 minutes to take in 1 ounce of fluid. You’ll also need to wait 15 to 30 minutes before and 30 minutes to an hour after each meal to begin drinking.

Clear Liquid Diet: Fruit Juice

This stage of the post-surgery diet allows 4 to 8 ounces of fruit juice each day. In order to adhere to the portion guidelines, do not attempt to drink 8 ounces of juice in one sitting. Acceptable juices include apple, grape, and cranberry juice. Not all juices are transparent (i.e. citrus juice), so make sure to stay within these guidelines. You may also drink sports drinks like Gatorade and Power-Ade.

Clear Liquid Diet: Clear Fluids

Because the amount of juice you can drink is limited, there are other liquids to choose from to help you reach your required 64 daily ounces. Some options include:

  • Water
  • Coffee (in moderation)
  • Sugar-free tea
  • Crystal Light
  • Chicken, vegetable, or beef broth
  • Propel fitness water
  • Sugar-free flavored waters

Remember, sugar-free means sugar-free. As their names would suggest, reduced-sugar and low-sugar products still have sugar in them. Consumption of those products can slow your weight loss and upset your stomach. Also, when consuming sugar-free foods, you may find that you’re consuming a lot of sugar substitutes. If you find that these irritate your stomach or cause diarrhea, cut out the products that use them.

Clear Liquid Diet: Liquid Snacks

Clear-liquid snacks include sugar-free popsicles and gelatin. Be sure not to consume more than 1 or 2 ounces of gelatin, and keep in mind that ice pops work toward your 64 daily ounces of fluids.

Sample Diet

As an example, a day’s meal plan during Stage I might look like this:

  • Breakfast: 1 to 2 ounces of sugar-free gelatin
  • Beverages after breakfast: 4 ounces of apple juice and 4 ounces of water
  • Lunch: 1 to 2 ounces of sugar-free gelatin (try a different flavor for variety), or 8 ounces of hot chicken broth
  • Beverages after lunch: 12 ounces of Crystal Light and 8 ounces of water
  • Afternoon snack: Half of a sugar-free ice pop
  • Dinner: 1 to 2 ounces of sugar-free gelatin
  • Beverages after dinner: 1 cup of fat-free milk and 8 ounces of water
  • Understanding the Glycemic Index
    Carbohydrates are one of the six essential nutrients. Despite common talk about avoiding carbohydrates for weight loss, our bodies require them to thrive. Carbohydrates contain sugar. When you eat carbohydrates, your body breaks down that sugar and absorbs it into the cells with the help of a hormone called insulin, where it is then converted to fuel and used for energy.
  • Reasons to Consider Weight Loss Surgery
    Getting weight loss surgery is a choice that can have a major influence on your health and quality of life for years to come. The conversation surrounding weight loss surgery may come up at the advice of a doctor, after seeing a friend who was successful in their weight loss efforts or maybe after a series of frustrating weight loss attempts.
  • Managing Special Occasions after Weight Loss Surgery
    Every time you turn the corner there is another fast food restaurant or bakery loaded with its own temptations, and you do what you can to stand strong and stick to your post-bariatric diet plan.
  • Healthy Shopping Strategies for a Healthy Household
    When one person in a household gets weight loss surgery, it is actually common for other members of that household to lose weight too. This is called a “halo effect.”
  • Making Healthy Food Substitutions after Weight Loss Surgery
    Approximately six weeks following weight loss surgery you’ll start making the gradual transition back to a whole-foods diet. This is an exciting period for many people. After weeks of gaining sustenance through liquids and soft foods, being able to enjoy a regular meal is something to look forward to.
