Recommended Posts

Hi everyone! I see a lot of questions on this site about pre-op diets. I thought I'd post mine, just as a guide for those who aren't prescribed one, but think they might need or want one. Good luck to everyone. :confused1:

Pre-op liquid Diet

It is recommended by your surgeon and dietitian to follow a low calorie, low fat, low sugar and high Protein liquid diet for ___ days prior to undergoing bariatric surgery. The purpose of the liquid diet is to reduce the size of the liver, reduce the risk of bleeding during the surgery and to show commitment to the program. Below are the nutritional guidelines for the pre-op liquid diet. You will need to measure your intake and keep a food journal. Depending on which items you choose to consume throughout the day, your intake should be approximately 1000 calories and 60-80 grams of protein. You will be expected to lose 5 lbs per week on this plan. The nutritional guidelines are as follows:

UNLIMITED SECTION: These liquids can be taken in any amount since they do not contain sugar.

1. Sugar free or diet beverages such as Crystal Light (Great Value @ Walmart), sugar free Kool-Aid, Sugar Free Tang, Diet Snapple, FUZE, Powerade Zero, Diet V8 Splash, Propel, fruit 2 O, coffee, Tea and Water.

2. Low Sodium broth Soups (chicken, vegetable, beef- Tomato Soup is not a broth soup). It needs to be a clear liquid and can NOT contain bit and pieces of meats, tofu, noodles or vegetables. Each 8 oz serving shouldn?t be more than 140 mg of sodium. Bullion cubes are not acceptable as they are too high in sodium.

3. Sugar Free Jell-O and Sugar Free Popsicles

If you chose a brand that?s not listed above please check the nutrition label first and make sure it meets the following criteria: less than or equal to 160 calories, less than or equal to 6 grams of fat, 15+ grams of protein and less than or equal to 6 grams of sugar.
