Narrative review describing biochemical mechanisms without systematic review or new empirical data.

What was done
This narrative review synthesized proposed biochemical mechanisms by which the ketogenic diet alters brain amino acid metabolism during the shift from glucose to ketone body utilization.
What was found
The abstract reports no numerical data. It presents biochemical pathways showing that ketosis leads to: (1) reduced glutamate transamination to aspartate due to decreased oxaloacetate availability, (2) enhanced conversion of glutamate to GABA, and (3) increased brain uptake of neutral amino acids coupled to the export of glutamine, removing glutamate from the synaptic space.
Why it matters
It outlines a coherent metabolic framework for how dietary ketosis may shift neurotransmitter balance away from excitation to suppress seizures.
Limits
The abstract describes theoretical and mechanism-based models without providing primary clinical trial data, sample sizes, patient populations, or quantitative effect sizes.
