I would say:
- What about small game kills which they hunted daily, caught, and ate every night (although smaller) and repeated.
- Season issues with more light in the summer to hunt game....but isn't this also the time they are stocking up on fat by eating as many fruits as possible?
- Paleo man layed around alot and went to sleep when it got dark, so he could have an easier time fasting than most people today running around and burning more energy.
That and I just like food.
All in all, I think longer fasts have huge benefits....but should be cycled in around shorter IF windows and occasional all you can eat days. EOD is not an accurate portrayal in my book.
