Preoperative Liquid Diet for Gastric Sleeve
Both before and after gastric sleeve surgery it is important that you adhere to the diet guidelines provided by the bariatric company you go with. The purpose of the guidelines is to help ensure that both the surgery
and your recovery go as smoothly as possible.
By learning your current weight and overall BMI, your bariatric surgery provider can best plan the duration of your preoperative gastric sleeve diet. This preoperative diet consists primarily of liquids to help ensure your stomach is prepped for the procedure. The two meals you can eat consist mainly of protein, healthy fats, and vegetables.
The Purpose of the Preoperative Bariatric Surgery Diet
When a patient undergoes the dietary changes involved in the preoperative diet, it helps to prep them mentally and physically for surgery. Your diet after surgery will be much different after surgery as your stomach size will be significantly reduced. In the postoperative diet, you will also be required to do a liquid phase and gradually transition over to solids again.
It is not recommended that one tries a liquid diet for long-term weight loss. The liquid diet is only suggested in this case as it proves beneficial for certain bariatric procedures such as a gastric sleeve.
Fluids You Can Have
The key to a successful preoperative liquid diet is to keep it low in sugar while maintaining a balance of high protein with healthy fat and carbohydrates. The key is to read the labels. All protein drinks you chose need to have less than 5 grams of sugar. All other liquid options should not have any added sugar.
Here is a list of many options available:
- Vitamin or Sobe Life water
- No sugar Coconut water
- Sports drinks such as Propel and Gatorade – sugar-free
- Sugar water soluble options such as Crystal Light Pure and Flight
- Sugar-free or low sugar fruit juice
- Hot or iced herbal tea
- Whey protein powder mixed with almond/cashew milk or water
- Plant-based protein powders
- Orgain High Protein
- EAS Advantage
- Muscle Milk Light
- Carb Solution Shakes
- Bariatric Advantage
- Low carb Slim-Fast shakes – High Protein
- Vegetable or bean soups
- Sugar-free gelatin (Jello)
- Low sodium meat and vegetable broths (This is a very helpful source of protein)
- Teeccino or Pero (herbal coffee alternatives)
Your daily intake during this stage should not go below 1200 calories. The goal is to minimize all processed foods and added sugars as you do not want to overdo in your intake of fluids. Too much intake of fluids can be damaging to your health.
You can drink protein drinks to help ensure proper nutrition; sticking with a minimum of 3 per day.
