Have you tried "bulletproof coffee"?

Have you tried "bulletproof coffee"?

I don't think I can do it!
"Bulletproof coffee" is the latest craze in the coffee world. It was inspired by the traditional Tibetan yak butter tea, which is black tea blended with yak's butter, milk, and salt. Entrepreneur David Asprey optimistically decided to import this concept to America by adding butter to coffee.
 
Bulletproof coffee is a blended mix of coffee, butter, and MCT oil. Its adherents claim that it is not only delicious (a claim I find dubious), but that it also helps with weight loss by burning fat, keeping your appetite down, and increasing your metabolism.
 
Frankly, even if it worked (which I'm sure it doesn't), I don't think I could bring myself to try this stuff!
