Re: gotta love the quotes in fastcompany
2 ½ heaping tablespoons ground Bulletproof Coffee Beans
1 teaspoon – 2 tablespoons Brain Octane Oil
1-2 tablespoons grass-fed, unsalted butter or grass-fed ghee.
From the above I think you have to start off weighing in at 25 stone. Adding 2 tablespoons of "Brain Octane Oil" (it is actually just 100% coconut oil) plus 2 tablespoons of ghee into coffee would make me seriously ill. IMO Butter belongs on toast, crumpets, baked potatoes and as yak butter in the occasional history monk's tea.
Here's a better solution Try to eat less and exercise more.
