Startled from his dream of a holiday in the depths of the Monteverade forest in Costa Rica, Miraan Punjabi drags himself out of bed. It’s 6:30 a.m. and he’s ready to pump-prime his day with his morning dose of energy—his make of the ‘Bulletproof’ coffee: ‘grass-fed unsalted butter’ quickly blended into his dark roast coffee brew, with a dash of vanilla. And wait. A dollop of coconut oil. Bulletproof, aka Ketoproof, coffee is Punjabi’s new power drink. All of Silicon Valley, where this energy booster was formulated, swears by it: the Medium Chain Triglyceride (MCT) in the coconut oil, or brain octane oil that is alternatively used, is the secret ingredient that kick-starts the day for countless techies.
