I'm supposed to be on a clear liquid diet from 6 a.m tomorrow until 2 p.m the following day. This is because I am having a medical procedure done. Is protein whey and water acceptable for this? What reccomendations can you offer to get some nutrients. I know I can have beef, vegetable and chicken broth but I was hoping for a little more supply of nutrients. If this is all I can have, then how much and how often?
