Postprandial Light Exercise Attenuates the Glycemic Effect of a Candy Bar

This study investigated the ability of healthy young adults to walk 30 minutes postprandially to attenuate the glycemic response to a candy bar. Seventeen volunteers had blood glucose measured at baseline, 30 minutes, and 60 minutes on 3 days. Participants walked lightly for 30 minutes postprandially on day 3. Without postprandial exercise, there was a blood glucose spike; the differences between baseline, 30-minute, and 60-minute values were significantly different (P < .01). With postprandial exercise, baseline and 30-minute values were not significantly different. In conclusion, light walking for 30 minutes postprandially can blunt the spike in blood glucose.
