Gut microbiota-fatty acid oxidation interplay in aging: Mechanisms, controversies, and translational perspectives

Figure 2 Context-dependent effects of fatty acid oxidation in aging. Reduced fatty acid oxidation (FAO) favors lipid accumulation, metabolic inflexibility, and energetic failure, whereas excessive or dysregulated FAO may increase mitochondrial burden, oxidative stress, and senescence-related signaling. These opposing effects indicate that FAO must be tightly regulated to preserve metabolic homeostasis during aging.
