Is Isopure considered a clear liquid for purposes of the clear liquid post op diet? I have never used Isopre. But it sounds like a way to get in protein and water at the same time. It seems to be protein water. When I called my surfeon's office and described it to them, they said it sounds okay. It has zero carbs. It is sweetened with sacral owe. On another website, I saw that one surgeon's opinion is that isopure must be diluted with 50% water in order to be drunk during the post op clear liquid diets take. What are your experiences? Is there a good reason to dilute it? All thoughts are welcome.
