The longest I have gone without food was 6 days. That was when I had my two back surgeries - back to back, so to speak. After my first surgery, they realized that my back would totally collapse if I attempted to stand up, so they had to go in agian through my stomach to stabalzie my spine. They waited 48 hours between surgeries, and after I came out of the second surgery, they told me that I couldn't have any food until I had .......uh, done my dooty. I tried explaining that wasn't going to be very likely, because I had by then been without food for 3 days, but the doctor would not change the orders. So, all together between going in the hospital, waiting betwen surgeries, and then waiting again; the only thing I comsummed for six days, except juice and tea, was celery jell-o.
