It’s odd to think that depriving yourself of a necessity for life might be one of the most powerful ways to transform your health. Yet there’s more and more evidence for the idea that fasting could have powerful health benefits for both the body and brain.
There are many different forms of fasting, ranging from going extended periods without food to consistently eating less (perhaps cutting caloric intake by 20%) to intermittent or periodic fasting.
But of all these different kinds of fasting, intermittent fasting is very likely the most popular and certainly the trendiest one. Celebrity adherents include Hugh Jackman, Tim Ferriss, and Beyonce. In Silicon Valley, whole groups of self-optimization-obsessed biohackers meet to collectively break their fast once a week, and executives at companies like Facebook say fasting has helped them lose weight and have more energy.
