I’ve been on a keto diet almost exclusively for over 2 years now. Results have been very impressive for me. Not just in weight management, but also for fitness/performance. Anecdotally, cognitive performance/output feels like I’ve moved the needle in the right direction. Not sure if related, but multiple tests on telomere measurement(associated with cellular ageing) show “genetic age” well below my chronological age. Despite all of this, I really don’t know. The low carb and no sugar diet really seems to work for me. If I had to guess, I’d say there is no single overwhelming factor to increasing longevity. I think brain health is a mix of: Healthy nutrition Hydration Fitness/activity level Sufficient sleep Low stress(but not no stress) Purpose People in your life Traumatic brain injury prevention Life long education Reading as a hobby No smoking But in terms of mental agility(if not brain aging), I have a feeling that some low level of hunger is a positive indicator of short term mental agility. I reckon there’s a high performance zone for brain health/performance for both short-term and long-term. I look forward to more quantifiable research in this space. Just my amateur 0.02c
