Why Is A Liquid Diet Needed?
The purpose of a liquid diet before bariatric 
surgery is not simply to place another 
roadblock in front of you; instead, it’s to 
make sure the surgery goes as smoothly as 
possible. Typically, this liquid diet is done for 
about 2 weeks just before the date of 
surgery.
Tips to Make the Liquid Diet Work
Read the Nutrition Facts Label
The nutrition labels will help you 
estimate the total calories of your 
liquid diet and ensure you are 
meeting your protein needs, while 
avoiding too much sugar.
Space Out Meals & Snacks
Eating everything at one time will 
make it harder to manage hunger 
throughout the day and will cause 
stomach problems after surgery.
Avoid Restaurants
Very few things on the menu will be 
acceptable choices and it will only 
make it more difficult to stay on the 
diet.
Stick to A Grocery List
It is much easier to have self-control 
once per week at the grocery store 
then to try to avoid tempting foods all 
week.
Focus on the Big Picture
Remember the reason you are 
choosing to undergo surgery and that 
liquid diets are ultimately temporary.
Summary
Many surgeons require a special pre-op liquid diet before bariatric 
surgery that lasts about 2 weeks. The purpose of this diet is to start 
losing weight, get used to liquid diets, and reduce liver size. These 
factors ultimately help to ensure the best surgery outcome.
