There is growing evidence to support a very low calorie diet (VLCD) before bariatric surgery. The objective of the VLCD is multi-leveled. Patients have a “kick-off” weight loss prior to surgery which is an encouraging start for most. Moreover, while this plan is not meant to assess compliance, this diet helps patients realize the commitment they have to the bariatric surgery process.
Surgeons, on the other hand, may benefit intraoperatively from the reduced liver. Studies have shown significant preoperative weight loss (-2.4 to -14.8 kg) and a reduction up to 20% in liver volume.
The 2-week diet plan includes protein shakes, fruit juice, and water mixed with an electrolyte drink mix. These beverages were selected to ensure patients consume an appropriate amount of calories, protein, and electrolytes like potassium and sodium. Special care needs to be taken for patients who have diabetes to prevent low blood sugar. A modified version of the plan also exists for patients with chronic kidney disease.
While this protocol is may seem difficult, patients are only instructed by their medical team to initiate this diet when their bariatric surgery is scheduled.
Did you have to follow a diet prior to your bariatric surgery?

I had bariatric surgery in 2013, did not have to do VLCD prior to surgery, but did have to attend a 12 week program to learn and show I can make life style changes. I did loss weight prior to surgery. I also stopped drinking alcohol.
Seeing bariatric surgery is not a quick fix, the idea for VLCD prior to surgery makes sense. If can not accomplish a two week commitment, you will have a hard time after surgery.

1 ReactionHi Laurie! You're right, this protocol is new and was not in place here in Rochester in 2013. We still have patients attend the 12-week lifestyle program through our psychology colleagues, which I think is so helpful. It sounds like you took it seriously and had success! I love that you mention that surgery is a lifelong commitment. What helps you stay on track almost 10 years later?
I have had ups and downs in weight lost over last 10 years. One thing I highly recommend is a yearly recheck in endocrinology area. They check blood work, discuss obstacles, make recommendations, etc...

I'm so happy to hear that, Laurie! I happen to be part of that team! The annual check-in has been shown in a wide variety of research to predict better weight outcomes for patients. Whether you're doing great or struggling, we want to see you, regardless 🙂
