I am on day 4 pre-op. My diet is 3-4 protein shakes and a 400 calorie meal at night. I have a limit of 1,000 calories. I've been hanging around the 800 calorie mark and getting at least 70-80 grams of protein.

I've read that you can add sugar free pudding mix to protein shakes to change the flavor. I thought it was a great idea. My question is this, can I mix a pack of sugar free pudding and a protein shake together and let it set up to a protein pudding?

I did it today and it was awesome. I had 1/2 a serving today. ( 1/2 pack sugar free pudding, 1/2 a protein shake). The pudding adds 100 calories per box so I didn't want to eat more than the half serving. Do you think that is okay? Does it make a difference how your shakes are mixed? I don't see the difference if I drink it before its set vs. when it's set.

Thanks in advance

Don't think it makes a difference. A calorie is a calorie. As long as you meet your guidelines you should be good to go.

Glad to hear you are sticking with preop diet. Torture, but totally worth the final results.
