I think thats crazy.....after my operation I was on liquids for 2 weeks...they just advised me that once you could suck it through a straw then it was ok to eat.....I took vitamins that diluted in water and I took celebrity slims protein shakes....I was also told I could drink any drink which they give old people who cannot eat when in hospital ....I think its called Complan ......I also had soup broths.....and soya yoghurts / custard which is a natural source of protein ......I think a week of clear fluids is drastic.....and this will make you lose weight quick but not help you rebuild body muscle and tissue post op.....I would just take the shakes like I and others have done....my doctor encouraged me to take protein drinks as he said I needed my body to recover and aid the healing of the wounds

Isopure has a good tasting, clear, liquid protein drink. you can even print a coupon from this site. I purchased mine at GNC.

Also, there are tubes of a clear liquid protein shots. I purchased mine from WalMart & Target. you can buy them individually or in packs. they help w/energy and protein consumption. they are clear.

I am not home right now but if you send me a reminder later, I will look up the exact names and get back to you.
