The ketone body beta-hydroxybutyrate (BHB) is an acidic energy metabolite that is synthesized during periods of fasting or exercise. Our previous study demonstrated that an every other week cyclic ketogenic diet (Cyclic KD), which induces blood BHB levels similar to those observed during fasting, reduces midlife mortality and improves memory in aging mice. In addition to its canonical role as an energy metabolite, BHB regulates gene expression and inflammatory activation through non-energetic signaling pathways.

We identify β-hydroxybutyrate (βHB), a ketone body, as a regulator of protein solubility. βHB primarily provides ATP substrate during periods of reduced glucose availability, and regulates other cellular processes through protein interactions.
