Who is the founder of bulletproof coffee?

The creator, David Asprey, found the recipe while hiking in Tibet. The drink requires coffee beans with low mold content, two tablespoons of grass-fed animal butter, which is richer in omega-3 and vitamins, and two tablespoons of medium-chain triglyceride oil. The end result is a 450-calorie cup of breakfast coffee that is said to give drinkers a clean caffeine rush and promote weight loss.
