Keto Diet and the timeline please help.

[redlirpa 6]

I am just in the initial stages for pre op my surgeon appointment is on Tuesday but as I go grocery shopping I want to fill my fridge with the pre op diet foods, and have read most doctors diet pre surgery is Keto. I have been doing the whole30 and have lost 30 pounds in the past 3 months and can transition to keto if that's what I'm going to be put on, in my research I'm seeing that keto is listed as the worst diet of 2017 and whole 30 was right with it. My bariatric may require 3 months dietician, exercise and weight loss. My insurance doesn't, Just failed attempts and need. I'm curious about keto diet recommendations, how much weight are you suppose to lose before surgery? How many carbs do you eat to be in ketosis, how do deal with the side effects?

Thank you

This is a tough subject that really should be discussed with a nutritionist, but I can tell you that the pharmacy sells ketosis test strips. Also I made the mistake of shopping for post OP foods prior to surgery and I have tons of pudding I'll never eat and Protein Shakes I can't tolerate...
