Here in Seattle we love our coffee, so one that purports to “upgrade your head” caught our attention. We also have our fair share of coffee entrepreneurs (Starbucks anyone?) and it’s tempting to believe that a breakfast which starts out with two tablespoons of butter is going to be the cornerstone of a diet that provides for “more energy and willpower than you ever thought possible.”

A new restaurant, Bulletproof, just opened in Santa Monica, with openings planned for Seattle, Los Angeles, and Milwaukee, in case you’re wondering where you, too, can upgrade your head. Or you can check out the website and buy the high quality, low mold beans on-line while learning more about a diet trend which has stars from Jimmy Fallon and Shailene Woodley raving. Others, from Christopher Gardener, professor/diet expert at Stanford University’s School and Dr. Walter Willet, chairman of Harvard Medical School’s department of nutrition, are more skeptical. Gardener notes “If I gave this diet to 100 people and tested their weight, blood-glucose levels, and LDL cholesterol, some would benefit, some would be neutral, and some would get worse.”

The Bulletproof diet touted by entrepreneur Dave Asprey has people starting the day with Bulletproof coffee – a blend of his high quality beans ($18.95/pound), butter made from the milk of grass-fed cows, and a medium chain triglyceride (MCT) derived from coconut oil – and if you’re like Asprey, a self-described biohacker, a mix of 20 vitamins including K and C to help improve brain function.  (What is a biohacker? Somebody who uses science and technology to improve body function.) There’s also a book and a color-coded roadmap to help you avoid foods in the kryptonite region) available from Bulletproof. To be fair, low-mold beans are less bitter than regular ones, and we’re all for that. And as Asprey notes, “if I start to die, I’ll know it’s not working.”
