I've jumped on the Bulletproof coffee bandwagon. For the last three days, I've had 1tbsp grassfed butter (not Kerrygold, some Icelandic brand) with my morning coffee. The resulting energy and mental clarity is amazing! During the morning hours I've been completely awake and focused/interested in my work. The feeling is similar to when I used to (ill-advisedly) take adderall as a college kid to pump out 30 page papers overnight - albeit via a much much healthier means. I suppose my body was screaming for MOAR FAT?
