It’s old news by now that fasting isn’t just for eating disorders and acts of religious piety. Intermittent Fasting (IF) has been picking up steam for quite a while now as a tool for both weight loss, health and energy benefits.

And if there’s anything the tech business want is something they can use to improve their energy and attention levels.

The tech industry has brought us some great stories lately from people micro-dosing LSD to help their creativity and problem solving to drinking Soylent rather than actually wasting time eating.

We hear stories all the time about countries and their insane work culture — but this is actually one which could be improving things rather than unhealthy trends being chosen over health.

While Soylent fans persist, it’s no longer the latest trend. The newest food trend among techies is to avoid eating at all. For some, the formula is simple — just eat once a day (usually dinner). This approach is the one that has apparently been adopted by Twitter CEO Jack Dorsey who tweeted earlier this year that he’s “been playing with fasting for some time” by doing a 22-hour fast daily. Others take a more extreme approach. Phil Libin, the founder of the AI company, All Turtles, fasts for periods of two to eight dayson a regular basis.

IF is not a new thing. I’m not breaking new ground here in that regard but more and more big names are certainly throwing their weight behind it.

In today’s workplace, bandwidth — the attention, energy, and focus needed to execute projects — is at a premium. As a result, in hyper-competitive spaces, like Silicon Valley, people are trying to streamline and simplify life. By finding more time, more energy, and more focus, they can become more productive. So, people are eliminating what they don’t need whether it means eliminating clutter to create a cleaner and more focused environment, eliminating mundane decisions (this is why Steve Jobs wore the same outfit to work every day), or eliminating daily rituals (e.g., eating). By cleaning house on all levels, they are creating more time to focus on what really matters.

Coined in The Productivity Project the new currency in tech is not the number of hours you’re able to sit at your desk. It’s the attention and focus you’re able to employ during that time.

There are a myriad of studies pointing to energy level increases from IF and it’s generally considered as a safe thing. Especially in comparison to the other options, the tech industry has been trying.

In a recent Harvard Medical School publication, Dr. Monico Tello observes that for the most part, research suggests that intermittent fasting holds many benefits. As Tello writes, “There’s a ton of incredibly promising intermittent fasting (IF) research done on fat rats. They lose weight, their blood pressure, cholesterol, and blood sugars improve… but they’re rats.” Fortunately, as she further notes, “Studies in humans, almost across the board, have shown that IF is safe and incredibly effective.” The only bad news may be that, according to Tello, intermittent fasting may not be much more effective than any other diet.

There are plenty of books like this available on Amazon which help you break into (or improve) your fasting routine and you can see the same kind of energy and focus boost the owner of Twitter gets.
