Description (Abstract): Early inflammatory joint diseases and borderline seropositive rheumatoid arthritis (RA) are characterized by circadian symptom exacerbations, most notably early morning joint stiffness. While omega-3 fatty acids and ketogenic interventions have been studied independently, the immunometabolic synergy of combining chronic plant-derived omega-3 polyunsaturated fatty acids (alpha-linolenic acid, ALA) with acute ketogenic medium-chain triglycerides (MCT) has not been systematically conceptualized.We model the biochemical interplay between: (1) chronic dietary ALA as a competitive inhibitor of the arachidonic acid cascade and precursor to specialized pro-resolving mediators (SPMs), and (2) acute hepatic conversion of C8/C10 medium-chain triglycerides into beta-hydroxybutyrate (βHB), a known endogenous inhibitor of the NLRP3 inflammasome (Nature Medicine, 2015) and class I histone deacetylases (HDACs). In an illustrative N=1 observational setting of a 53-year-old female with prior borderline autoimmunity (titer 49 vs. 50 threshold) and 6-month persistent morning stiffness, acute MCT administration following established ALA intake resulted in immediate, complete alleviation of morning stiffness overnight. This paper proposes the Dual-Lipid Metabolic Synergy Hypothesis to guide future clinical investigations.
