Hormonal

Exercise-induced skeletal muscle secretion of IL-6 mediates metabolic crosstalk, specifically enhancing glucose uptake and fatty acid oxidation within muscle and stimulating hepatic glucose production during exercise.

Regular exercise triggers your muscles to release IL-6, which helps your muscles use more glucose and fat for energy and signals your liver to release glucose when needed. This hormonal communication is a key reason why exercise improves metabolic health beyond just burning calories.

GoodSupportsHIGH confidence
It is well documented that IL-6 increases both basal glucose uptake as well as glucose transporter GLUT4 translocation... IL-6 signaling within the muscle can affect both glucose uptake or whole body fatty acid oxidation via AMPK activation... Muscle-derived IL-6 plays a role in triggering glucose output from the liver during exercise in humans.
