Twitter’s CEO, Jack Dorsey, doesn’t eat for 22 hours of the day, and sometimes not at all. Over the weekend he tweeted that he’d been “playing with fasting for some time,” regularly eating all of his daily calories at dinner and occasionally going water-only for days on end. … And while researchers are hopeful that some types of fasts may be beneficial to people’s health, plenty of tech plutocrats have embraced extreme forms of the practice as a productivity hack.

For people with eating issues, though, fasting can be a very risky trigger for anorexia or bulimia.
