I've done it before a medical procedure, for 24 hours. I was allowed white grape juice, clear broth, and some other clear juice. I went through a full work day on juice alone (I had one cup of beef broth and didn't like it), and did fairly well. I didn't initiate any heavy exercise. The juice took care of my carb needs and kept hunger to a minimum, and I believe that the fact that I did not exercise intensely minimized my need for protein. At any rate, I went back to weight training a couple of days after the procedure and wasn't appreciably weaker.
So, drink juice or other clear liquids, don't exercise intensely, and you should get through a day's fast with no particular after effects.
