I enjoyed this article that first appeared in the literary magazine, Harper's in May 2012. Not specific to intermittent fasting, the author covers some of the history of fasting experiments and research, as well as documenting his own experience with a longer fast. I found it entertaining reading on my fast day and found myself thankful I'm only fasting one day at a time! The only way I get through one day is knowing "it's only a day!"
