Extended fasting, intermittent fasting, 24 hour fasting, all seem to be part of the paleo lifestyle these days.
My personal experience extends back 50 years this spring. I first learned of it at a Yoga class at the Baba Sri Chand Ashram in Pine Hills Florida in 1968 and tried it out for the Equinox after a juice fast of three days. It made fasting part of my life from then on. Looking back, it seems like just a natural part of life to me, even when I have gone years without fasting, I always knew it was there for me if I wanted it.
I have not yet tried anything beyond a 5 day fast. I didn't see the need and personally I associated that with religious fasting, since that's the only examples I had heard of until this year. But some folks are seriously going without food for a month or more! Search "extended fasting"on youtube and you will see 30-60 fasts. As far as I can tell, the record is a little over a year. Excluding, of course, those who are not monitored and claim to have never eaten for decades.
