Hormonal

Endurance exercise significantly increases circulating beta-hydroxybutyrate (BHBA), which acts as a signaling molecule that inhibits histone deacetylases (HDACs) and activates the HCA2 receptor, promoting anti-inflammatory and neuroprotective effects.

Endurance exercise naturally boosts BHBA, which helps protect your brain and reduce inflammation. You don't need to force a ketogenic diet to get these benefits; regular aerobic activity is sufficient to trigger this protective signaling pathway.

GoodSupportsHIGH confidence
The ketone BHBA is the most abundantly increased metabolite (AUC) following EE... Mechanistically, the benefits of BHBA on cellular health might involve a BHBA-mediated inhibition of neuronal HDACs (Shimazu et al., 2013) and/or activation of the receptor HCA2 (GPR109) (Husted et al., 2017).
