Bulletproof Brewing Guide
Bulletproof Coffee is a drink consisting of Upgraded black coffee blended with grass-fed butter and Brain Octane oil. The recipe was created by Dave Asprey and first posted to his blog in 2009. Asprey claims that the drink boosts cognitive performance and weight loss, and it is consumed by sports people.
Asprey's recipe calls for the brewing of coffee made with "Upgraded" beans which are low in mycotoxins. To this, 1–2 tablespoons of grass-fed, unsalted butter is added, and 1–2 tablespoons of "Brain Octane" oil. The drink should be blended for 20–30 seconds until frothy.Preparation
Asprey has claimed that when used in combination with other "health hacks", the coffee helped to boost his IQ score by more than 20 points. His company claims that Bulletproof Coffee can aid cognition and trigger weight loss through ketosis.Dieticians say there is no scientific basis for these claims, and that any sense of alertness from Bulletproof coffee is "just a caffeine buzz."
Asprey believes that most coffee contains high levels of mycotoxins and that this "steals your mental edge and actually makes you weak". Physician David Bach has observed that coffee producers are already good at removing mycotoxins from their product, and that there is "no evidence that supports the idea that mycotoxins make you sluggish".
