Interesting passage in that even though many here only fast for health reasons, the spiritual/biblical guideline of “keeping it personal” still applies. I learned the hard way not to tell people (other than my wife…and now this forum) because of the reactions I get.
I did a sleep study at a clinic a couple years ago and made the mistake of telling the nurse that I was on day 5 of an extended fast. She freaked out and wanted to put me on an IV.
