About this trial
The purpose of this study is to evaluate the acute effects of exogenous ketone monoester (KME) supplementation on cognitive function in three groups of adults aged 19-55 years: (1) obese, sedentary individuals; (2) lean, sedentary individuals; and (3) lean individuals who engage in regular physical activity (e.g., collegiate or amateur athletes). The main questions it aims to answer are to:
* Assess the effects of acute KME supplementation versus placebo on cognitive, sensorimotor, and functional outcomes within groups. * Compare cognitive performance across the three groups.
The primary outcome is cognitive performance assessed using the NIH Toolbox Cognition Battery. Secondary Outcomes include sensorimotor performance, measured using the Senaptec Sensory System, and driving performance, assessed with a driving simulator.
