Diabetic Boost compared to Boost with High Protein?????

I am on the Boost diet right now,as I am going for surgery next week, but A good friend of mine asked me what is the difference between Boost with High protein compared to Diabetic Boost, I told her it was something to do with the sugar content. But she asked me if she used the regular high protein boost instead of diabetic boost, would she still be able to get her surgery done? And I don't know what to tell her. She has already bought boost but it is high protein. She is just waiting for her call, but I don't know what to tell her, and she can't return it so anyone, if you are reading this please help me . 

I am not getting no reply back from anyone on this topic. I have made comments about this on other posts, but all anyone has told me is Boost with high protein had more sugar then Diabetic boost, which I already realized that. Just want my question asked about the surgery, and if anyone has just used the regular boost for their liquid diet instead.
