LOL! Yes, often very strongly brewed coffee is considered bullet-proof in some parts. This is actually a process by which high amounts of fats are added to coffee and blended together. Unsalted butter or coconut oil is traditionally used. I have a link at the bottom of this post, if you want to see how it's done. Good quality fats are an efficient fuel source calorically...better than sugar. Even a lot of athletes are turning to high fat foods for their sustainable energy benefits and trying to steer clear of sugar.
