From his website: "Dave Asprey, founder of The Bulletproof Executive, is a Silicon Valley investor and technology entrepreneur who spent 15 years and over $300,000 to hack his own biology. Dave lost 100 pounds without counting calories or excessive exercise, used techniques to upgrade his brain by more than 20 IQ points, and lowered his biological age while learning to sleep more efficiently in less time.

Here he is advertising "bulletproof" coffee

Which appears to be coffee with butter added to it.
