Using the forearm technique, muscle substrate balances were measured in healthy volunteers
under the influence of a low dose intraarterial infusion of β-hydroxybutyrate. The
ketone body led to a prompt cessation of muscular release of glycerol and free fatty
acids, indicating inhibited muscular triglyceride lipolysis. This finding confirms
the concept of substrate regulation of muscle triglyceride lipolysis in vivo.
