Bulletproof coffee; some people swear by this stuff, some people hate it, some people will get really angry when you tell them you drink it (cos you know, arteries and stuff) but it's definitely becoming well known. And if you don't know what it is yet - it's when you add butter and/or MCT oil to your coffee. I'm kind of lukewarm about this stuff, I definitely don't think it is as vital to keto as many sites lead you to believe. I'm not a fan of drinking my calories, and boy does this have calories. Sometimes I just feel like having one, maybe every two months or so, so I came up with a recipe that works for me. This is not the original BulletProofCoffee(TM) or whatever, but it's an approximation. Everyone has their own version of how to make this, this is the one I like.
