So as a type 2 diabetic and lactose intolerant on top of it, what is good for me to use for the high protein all liquid diet before surgery?

I'm sure there are others, but I know that Bariatric Advantage meal replacements are lactose free and have less than a gram of sugar per serving.

Does taking lactaid help?
Costco has a protein powder orgrain brand name I think

That is a hard one fir sure. I found GENEPRO unflavored Protein powder. It has literally saved my life. I was on a 2 weeks of protein drinks before my RNY and then 4 weeks of protein drinks after my WLS. I am here to tell you, I had "THE BACK DOOR TROTS" the whole time I was drinking PREMUIR Protein drinks. I mean I coudn't hardly get out of the house. After all of that time my Surgeon told me that I was Lactose Intolerant. THANK YOU MISTER!! Now when I say that I couldn;t go out I mean I COULD NOT GO OUT without wearing a pad!! So I am now 3 and 1/2 years out and when I found GENEPRO I was so EXCITED!!! It is unflavored and I add it to my coffee every day. You can add it to anything. Just temper it in some warm water and then put it in the stuff and you can enjoy your drinks without any difference. It is a little more expensive but it is so worth it. I hope this helps you, I just wish I would have had it all along. BTWS it has 30grams of protein in 1 Tablespoon. Now there will be some that say it isn't 30 grams but I have used it with all of my labs coming out great!!

So glad to read other people using genepro. I use it every day and I am almost 1 month post op and still on purée diet. I add it to my coffee, tea, cream of wheat and soups.. by far the best I have had since I can't stomach protein drinks anymore..

It is the best stuff I have found. It is all I use now. Because I am able to eat REAL FOOD now!! I just wish I had found it 3 and 1/2 years ago. LOL
