Check out this recipe for a bulletproof coffee that will get your synapses snapping on armbars.
METHOD
Brew or buy a stinking hot coffee.
Using a blender, not a spoon, blend in two tablespoons unsalted, grass-fed butter, as well as 1 tsp-2 tbsp of MCT oil.
DISCLAIMER
Seriously, start slow with the amount of oil and build your tolerance up to avoid the kind of involuntary brown belt promotion you lose friends over and that get you banned from open mats.
