There is a small but growing trend among some Silicon Valley executives called “biohacking.” The term refers to extreme fasting not for the weight loss or health benefits, but for the productivity benefits.
Its proponents include Phil Libin, the former CEO of Evernote and current CEO of AI studio All Turtles; Y Combinator partner Daniel Gross; and Loic Le Meur, the cofounder of the LeWeb tech conference. Participants in biohacking swear off all foods for between two to eight days at a time followed by similar time lengths of time where they eat normally. During their fast periods, they’ll only consume liquids like coffee, tea, and water.
