Power of a Post-Prandial Walk: How it Works (Read on👇)
Go for a walk after a meal. This activates large muscle groups—like your glutes and quads—literally increases glucose receptors (GLUT4) on your muscles through an insulin-independent pathway.
In effect, the muscle contraction forces the GLUT receptors out of intracellular storage and to the surface where they can gobble glucose out of the bloodstream.
*For those who want the more technical definition: During exercise, the enzyme AMPK is activated. This triggers phosphorylation, or molecular tagging, of the protein TBC1D4, which in turn drives the movement of GLUT4 receptors to the muscle cell surface. The result is greater glucose uptake into the muscle.
*Exercise also increases muscle insulin sensitivity and boosts nitric oxide production, enhancing blood flow and nutrient delivery—glucose included—to the working muscles
