Interrupting prolonged sitting with brief (2-minute) bouts of light- or moderate-intensity walking every 20 minutes significantly reduces postprandial glucose and insulin responses in overweight/obese adults compared to uninterrupted sitting.

If you have a desk job or sit for long periods, do not sit continuously. Stand up and walk lightly or at a moderate pace for just 2 minutes every 20 minutes. This simple break significantly lowers your blood sugar and insulin spikes after meals, offering cardiovascular benefits comparable to a full workout without requiring extra time or high intensity.
