I do intermittent fasting most of the time and usually only eat once a day. The longest I've ever gone without eating is 71 hours. Not quite 3 days, but I could have easily gone longer. I wasn't even hungry at that point (day 2 was kinda tough), but stopped to keep from going into adaptive thermogenesis. That's the mythical "starvation mode" fat people claim you will go into when not stuffing your face with sugar every 4 hours. From everything I've read, you get there by not eating 3-5 days, which I was trying to prevent. I also didn't want to lose any muscle. Gotta keep up my Sherbro rep! Anyway, what is the longest you've gone without eating?
