Engaging in 10 to 15 minutes of light muscular contractions (such as brisk walking) within 15 to 30 minutes following major meals activates an insulin-independent glucose uptake pathway.

Contracting muscles trigger AMP-activated protein kinase (AMPK) phosphorylation, translocating GLUT4 transporter proteins to cell membranes and allowing skeletal muscles to clear circulating blood glucose directly, significantly attenuating post-meal glycemic spikes and pancreatic insulin strain.
