Premise there is that while "normal" (average neuro typical) brain works just fine with either glucose or ketones - it's different for non-typical brains. And

Premise there is that while "normal" (average neuro typical) brain works just fine with either glucose or ketones - it's different for non-typical brains. And through bypassing damaged or suboptimal glucose pathways, you also bypass problems that come with it. Of course it might also be that ADHD brains simply do come from evolution of what used to be Hunters (as opposed to Gatherers). It wouldn't be too unreasonable to think Hunters ate more fat and protein than Gatherers.
