The story ran in the British tabloid The Sun, then spread to The New York Post and outward into the gossipsphere, with dozens of sites straight up taking these peoples' word at face value. After all, it's more fun to print the story, make people mad, cash in on hate-clicks, then quietly retract it than it is to do the many, many hours of exhaustive research it surely would've taken to disprove their claim. Who's telling the truth? Every organism that's ever lived since the beginning of time, or these two randos? As with any story, we gotta hear both sides.
Turns out the couple was lying. Snopes printed an almost-immediate refutation, and The New York Post then printed two retractions to their earlier story after a full news cycle of eating up those sweet, sweet clicks (not that they needed to eat). The couple amended their story to say that they "do eat solid foods on a regular basis, just not as much as the next guy." So that's pretty much the same thing. "We've transcended the need for food and water" and "We do eat and drink, but probably less than some people" -- same difference. And definitely just as newsworthy. Who knew people ate different amounts?? Get them one of those long-ass Economist profiles.
The couple also identified as "Breatharians," which sounds like some race from a '60s Star Trek episode that's a heavy-handed metaphor for pollution. But really it means "people who absorb their energy from the Universe." And also eat and drink totally normally and all of this is nothing.
