High fat low carb diet is very good for your brain. IF you are interested in your health and improving your brain, go dig out some info from internet about Keto.
P.S. Always remember, the quality of your life depends on the quality of your thoughts. And the quality of your your thoughts depends on the quality of your brain(in this case body). Put good things in it.
Yes, I've heard about Keto before. Actually, I've applied a diet that is very close to that for a while. I have had the most energetic and healthy days of my life for about six months, but I have a chaotic work life, so I had to take a break for now. At that time, I had the opportunity to experience how nutrition was healing for both the mind and the body. It was unbelievable.
