Based partly on my research, a friend of mine started eating the same amount of butter I do: 4 tablespoons (about 60 g) per day. He described what happened:
I’m noticably smarter since I started butter. Immediately.
Faster insights, faster foreign language processing, increased creativity, faster at math-in-my-head. My video-gaming ability is better, which partly is a measure of my reaction time. Since I log my creativity similarly to my workouts I can view the increased production.
Started butter properly 3 days ago. Haven’t been sleeping well due to workload and digestive issues…yet still my performance keeps [improving]. I suspect it will be yet markedly better again once I get some proper rest.
I am experiencing creativity effects [similar to those] that resulted when I was mindhacking with various racetams along with sublutiamine and centrophenoxine. I have not been taking that brain-stack for a month because it was causing digestive problems. Suddenly with butter all the mind-hacking benefits have returned.
