Increased Cardiorespiratory Stress During Cycling After Ketone Monoester Ingestion

Nutritional ketosis refers to a state in which blood ketone bodies are elevated above normal basal levels, typically corresponding to a beta-hydroxybutyrate concentration ([β-HB]) of >0.5 mM. Acute ketone supplement ingestion rapidly induces nutritional ketosis without otherwise altering diet, and there is growing interest in the effect of this practice on exercise responses and performance. The limited studies to date have yielded equivocal …
