Earlier this week, CNBC a story on the top “biohacks”of Twitter CEO Jack Dorsey. Along with things like coldshowers,infrared light, and seven-minute high-intensity interval workouts, the list also revealed thatDorsey only eats one meal a day—consisting of a lean protein and vegetables—between 6:30 p.m.and 9 p.m.and he sometimes fasts for the entire weekend.
There was a huge storm on the internet, mostly on Twitter,attacking Dorsey. I don't want to attack him personally, but I take issue with an outlet like CNBC publishing this story in the first place and, even more so, why so many people—mostly young males—celebrate these kinds of“biohacks.”
But since this is out there, let’s try to leave Dorsey out of it and look a bit deeper into why CNBC’s coverage is so dangerous and why the reaction is so strong.
I don’t know how many calories Dorsey is eating in that two-and-a-half hourwindow, but unless it’s 2,500 (he also walks fivemiles a day) or he has a medical reason to be on such a restrictive diet (e.g., thyroid issues) what is being celebrated is behavior suggestive of an eating disorder. Eating disorders are deadly. Males may be to get help than females, though people struggling with an eating disorder is a man. So, for starters, celebrating this kind of habit as a “wellness biohack” . I at CNBC to change this headline. We’llsee what happens.
Second, there’s some serious gender bias going on here. Just imagine if a woman CEO of a mega-company made public the same kind of eating behavior? She would be criticized.So the fact that it’s celebrated in men but shunned in women is another sad reality in and of itself.
Third, it’s especially wild that so much of this broscience—performance and longevity-focusedpseudosciencelargely peddled by young men—comes from Silicon Valley, which I fear is becoming a bit of a parody. You’ve got uber-wealthy people who work in tech making apps focused on very questionable means to self-actualization (one of which is literally a ) who spend their free-time kite-surfing and apparently starving themselves while thousands of people are on the streets experiencing homelessness; measles cases are skyrocketing; and public school teachers can’t afford to live in the city.As I've written about in, one of the ways passion can go awry is when you get so caught up in the inertia of what you’re doing and the validation it brings that you lose the ability to see outside of it—you lose perspective. It seems this is happening in at least parts of Silicon Valley.
Finally, the kind of broscience peddled in Silicon Valley is not real science.There is no solid evidence that eating only between 6:30 p.m. to 9 p.m. does anything other than restrict the calories you are eating to a very small window (and probably make you quite hungry).There is no solid evidence that a ketogenic diet prevents or reverses cancer, as .Putting does not slow aging any more than putting butter on your toast., or taking a few naps instead of sleeping at night, is not as restful or good for your brain than sleeping for seven to ninehours at night.
Most of this stuff is still pretty fringe. But it’s becoming more of a regular job to keep it that way.
As Michael Pollanfamouslysaid, “Eat real food, not too much,mostly plants.”And ’ladd: Move your body often, sometimes hard. And sleep at night.
And finally, let’s assume for a minute Dorsey is only eating 1,000 calories in his window. He doesn’t need strangers enraged with him. He needs help. Direct your rage at CNBC for describing an eating disorder and calling it a “wellness biohack.”
