I start my pre-op diet on Good Friday, March 21st and have questions. I've read some folks are on a liquid only diet but my nutritionist has a different approach. We are to get at least 90-120 grams of protein per day from our protein shakes but we must also get 100 grams of carbohydrates each day. Was anyone else told to limit their carbs?

My surgeon's office and nutritionist has me on a very low (almost no) carb diet. The only carbs come from 1/2-1 cup veggies; rare fruit (if you can fit it in). I will say that this diet prepared me well before surgery and has caused me to drop weight quite quickly (and I've stuck to the diet religiously).

The main purpose of the pre-op diet is to deplete the liver of its sugar stores. The liver stores sugars, when the body isn't getting sugars from the food you're eating, it will signal the liver to let go of its stores. Tossing out its sugars will make the liver smaller. A smaller liver makes it easier for the surgeon to access the area where s/he will put the band.

Someone on a 2k calorie diet would eat around 300gm of carbohydrates. 100gm is not a huge reduction compared to what most people are told to do during their pre-op diet. My pre-op diet was 0gm carb for 2 days.

my Dr wants no more than 30 carbs a day

My preop diet was Atkins induction phase, which is under 20 g carbs per day.
