I want steak... day 8 of liquids

I am on day 8 of my pre surgery liquid diet. 

I stay full/satisfied on the shakes, actually usually am -1 shake for the day out of my allowable amount. 

today though I am really wanting steak! I was told I could have some all protein "snacks" if I felt I needed to eat or was starving on the shakes. 

Should I get a steak and have a small amount? or just stick with the protein? Surgery is March 1st
