Dave Asprey, founder of The Bulletproof Executive, is a Silicon Valley investor and technology entrepreneur who spent two decades and over $300,000 to hack his own biology. Dave lost 100 pounds without counting calories or excessive exercise, used techniques to upgrade his IQ, and lowered his biological age while learning to sleep more efficiently in less time. Learning to do these seemingly impossible things transformed him into a better entrepreneur, a better husband, and a better father. Dave is the creator of the widely popular Bulletproof Coffee, host of the radio show and #1 health podcast, Bulletproof Radio, and author of the New York Times bestselling book The Bulletproof Diet.
