Targeted Assessment of Cognition and Tactical-performance With Ingested Ketones

The goal of this study is to determine whether consuming a commercially available exogenous ketone supplement (KetoneIQ®) affects cognition, specifically marksmanship, under physical stress (i.e., exhaustive exercise). The main questions we seek to answer are: * Does the supplement save cognitive performance under stress compared to a placebo? * Does the supplement improve marksmanship under stress compared to a placebo?
