Question:
Are protein shakes considered liquid or solid?

How about tomato or V8 juice? Can you like eat string cheese and a protein shake together? Do you have to stop drinking water that 1/2 hour before a protein shake?    — Ginger M. (posted on January 28, 2003)

My surgeon considers protein shakes a liquid, and therefore part of our daily required liquid intake. No stop in drinking water, but no string cheese and protein shake together. Stop drinking protein shake 1/2 hour before eating.

Ginger, liquids are liquids. That includes any form of liquid, like protein shakes, tomato, V8 etc, etc... and the same rule applies-no eating with liquids as all you are doing is washing it thru the system. Remember the whole reason we refrain from drinking and eating at the same time is to have that full feeling from eating stick around a little longer.
