Can I use the cabbage soup diet in place of the VLCD preoperative diet?

The Very Low Calorie Diet (VLCD) is a preoperative diet used to prepare the body and organs for surgery. It specifically designed to help you lose a few pounds and bulk up on protein before the surgery in case you have difficulty consuming protein in the first few days after surgery. 
In this video, a viewer asks Dr. Matthew Weiner whether she can substitute the VLCD for the cabbage soup diet.
