One nice thing about the bulletproof coffee is that it relieves the pressure I've felt to keep cream in the house. Knowing I can use butter means that if I run out of cream, it's no big deal. Cream sometimes goes bad but butter seems to last forever. I only use 2Tbsp of butter when I make it so it's not a 400 calorie drink. Maybe a little more calories than using cream, though. Somehow the calories seem to take care of themselves on a high fat low carb plan.
