      Me too, but for me it depends on my weight. My current and long term normal weight is 178 lbs. Any lighter and I get shakey and light headed when I’ve gone without eating for 3 hours and go on a walk. Above this weight, no problems.

      When I hiked the PCT, I dropped to about 160 lbs, and I had to eat with urgency every 2 hours. Newborn babies also eat on this schedule. It makes me believe humans can only really process and store food for 2 hours and beyond that you start pulling reserves. This was also how I felt training for a marathon. I don’t care how fast you can run but it’s not healthy to do it for more than 2 hours. For me this was a half marathon.
