The brain is an energy-hungry organ. While it traditionally runs on glucose, emerging research shows that ketones may be a superior fuel for cognitive performance, particularly as we age.
Beta-hydroxybutyrate (BHB) crosses the blood-brain barrier efficiently and provides a stable, steady energy source without the glucose spikes and crashes that impair concentration.
Studies in older adults with mild cognitive impairment show improvements in memory recall after as few as 6 weeks on a ketogenic diet.
Anecdotal and emerging clinical evidence suggests that the steady energy provided by ketosis may reduce ADHD symptoms and improve focus in both children and adults.
The ketogenic diet originated as an epilepsy treatment. Researchers now study it for Alzheimer’s, Parkinson’s, and other neurodegenerative conditions. The hypothesis: reduced glucose metabolism in the ageing brain can be partially compensated by ketones.
Omega-3 rich foods like salmon and walnuts support brain health alongside ketosis. Explore our keto main dishes featuring fatty fish, and our gluten-free keto recipes for anti-inflammatory options.
