Okay, I just ate my first meal in 72 hours, and boy, was it good :) To be honest, I never felt THAT hungry, and my stomach didn't even growl until today, and it wasn't much. Maybe it is because I am pretty old (66) that I can take going longer without food; lower metabolism perhaps. I felt weaker than normal, but never debilitatingly weak; I even walked over an hour yesterday. What is weird is that I lost 5 lbs of body weight, but the lack of calories would equate to not much more than a pound of fat loss; I guess the body just start getting rid of water if you go without food, but I stayed hydrated; pretty weird. Now I have to see if I feel a lot better than normal in a day or two. It definitely was not as hard for me as some people make it out to be.
