Viewing $\beta$-hydroxybutyrate (BHB) as just a backup fuel source is a mistake. The SCOT-bottleneck isn't only an ATP issue; it’s a failure of epigenetic gatekeeping. BHB stands as one of our most effective endogenous HDAC inhibitors. When we lose the ability to process ketones efficiently—falling off the "ketolytic cliff"—we aren’t just losing energy. We’re losing the molecular signal required for high-fidelity synaptic remodeling in the entorhinal cortex.

This is a problem because the entorhinal cortex acts as our internal GPS for both physical space and temporal navigation. There's a direct link between metabolic flexibility and our capacity for long-term temporal projection. Chronic glucose saturation essentially glues the brain to the present. The machinery needed to simulate complex, decade-spanning counterfactuals requires the specific signaling environment that only ketolysis provides.

We might be witnessing a civilizational "short-termism" driven by metabolic stagnation. If the brain can’t access the BHB-mediated HDAC inhibition needed to rewire its internal maps, it stays a biological prisoner of the immediate. We can't imagine a world 100 years from now because we literally lack the epigenetic "ink" to draw that map.

This goes beyond longevity; it’s a matter of cognitive ecology. We have to stop treating ketones as fat-loss tools and start seeing them as essential ligands for future-state simulation. I’m looking for collaborators who can bridge the gap between ketone kinetics and predictive coding models. If we can prove that ketolytic capacity predicts a person’s ability to plan for their "future self," we change the conversation from metabolic health to existential autonomy. We need to map the BHB-HDAC-Temporality axis before we lose the metabolic capacity to even care about the results.
