Short‐term ketone monoester supplementation improves cerebral blood flow and cognition in obesity: A randomized cross‐over trial

Adults with obesity are at increased risk of neurocognitive impairments, partly as a result of reduced cerebral blood flow and brain‐derived neurotrophic factor (BDNF). Ketone supplements containing β‐hydroxybutyrate (β‐OHB) are a purported therapeutic strategy for improving brain health in at‐risk populations. We tested the hypothesis that short‐term β‐OHB supplementation will elevate cerebral blood flow and BDNF, as well as improve cognition...
