Actually it kind of makes sense to me in that more studies are coming out that butter from grass fed cows is actually very healthy fat (which takes longer to digest) and that mixed with the coffee would extend the digestion period making the coffee stimulant effects last longer. The MCT is just an added ingredient that has been found to have healthful benefits as well.

The guy admits he's not a doctor but this has worked for him from his "biohacking" experience. Interesting reading at the very least.
