Lifestyle Strategies and Mechanistic Implications for Slowing Neurodegeneration (Paper March 2026)
A 2026 narrative review in npj Metabolic Health and Disease by Gunning et al. evaluates four lifestyle interventions—intermittent fasting/ketogenic metabolic switching, calorie restriction, high‑quality diets (Mediterranean/MIND/DASH), and exercise—as strategies to slow neurodegeneration, especially Alzheimer’s disease. The authors map each intervention to shared mechanistic pathways, highlighting reduced neuroinflammation, enhanced autophagy, lower neuronal death, and attenuated amyloid‑beta accumulation, with particular focus on the AMPK‑SIRT1‑PGC‑1α axis, mTOR suppression, TFEB‑driven autophagy, and BDNF up‑regulation. Novel aspects include integration of recent 2024‑2025 studies, detailed discussion of SIRT3’s role in alternate‑day fasting, and the gut microbiome as a common mediator. The review notes that most evidence remains pre‑clinical and that human trial data are limited, cautioning against over‑extrapolation.
