I don't think it's any more complicated than that.
“intermittent fasting gave a 20% edge in memory and executive memory “
How would Brandon fare with intermittent fasting?
How about frequent fasting?
How about continuous fasting?
Or, what if he went all the way to PERMANENT fasting?
Fasting activates the autophagy regenerative process and has been shown to have very beneficial neuroprotective effects on the brain and nervous system.
Fasting or a fasting mimicing diet can be a very effective treatment for epilepsy and Multiple Sclerosis and other auto immune diseases.
It is also very effective at preventing dementia and managing other degenerative brain and nervous system diseases

Prolonged fasting of 14+ days has been shown to reverse epilepsy symptoms and even provide a complete cure in some patients.
Periodic cycles of on /off fasting consisting of 5-7 days of fasting stage to induce autophagy followed by a regenerative period ranging from several days to 4-6 weeks with a well controlled , preferably ketogenic diet is very beneficial for managing Multiple Sclerosis and has even been shown to initiate and promote re mylination in lab testing - the holy grail of MS research.
Similar fasting cycles combined with a ketogenic diet can also be effective in managing other neuro degenerative conditions like dementia and Huntington's disease by scavenging amyloid and other toxic protein accumulations that damage brain and nerve tissues during the fasting cycle followed by neuroplastic healing and regeneration during the non fasting phase of the cycle.
Coming from the same folk who had the food pyramid upside down for generations.
