Researchers elucidate various exercise parameters influence post-meal glucose responses in healthy and diabetic individuals.
By Dr. Priyom Bose, Ph.D.Apr 18 2024Reviewed by Benedette Cuffari, M.Sc. In a recent study published in Nutrients , researchers elucidate various exercise parameters, such as timing, type, intensity, and volume, influence post-meal glucose responses in healthy and diabetic individuals.
Pre-meal exercise induces insulin sensitivity and fat oxidation by promoting glycogenolysis, which subsequently stabilizes blood glucose levels and prevents hypoglycemia. In the prandial state, glucose is primarily derived from exogenous sources. Thus, the performance of exercise closer to any meal leads to optimal benefits in glucose management. As compared to pre-meal exercise, post-meal exercise has greater benefits in controlling blood glucose levels for both non-diabetic and diabetic individuals. Several factors, such as exercise intensity and volume, and nutrition status, are responsible for the differential effects of pre- and postprandial exercise.
Among the various forms of exercise, cycling at varied intensities significantly reduces post-meal glucose excursions. Furthermore, a 30-minute moderate-intensity walking, elliptical exercise, cycling, or jogging lowers post-meal glucose peak and three hours of postprandial glucose levels in non-diabetic/healthy people. Alternative exercises, such as stair climbing and descending, also have beneficial effects on glucose management in people with diabetes.
Exercise duration and intensity for optimal postprandial glycemic levels Exercise volume, duration, and intensity must be suitably customized to accommodate an individual’s capacity. To date, no clear guidelines have been published on the optimal exercise volume to control post-meal glucose levels.

Researchers Find Commanding AI Robots Differently Improves PerformanceResearchers from UC Berkeley and Stanford University found that commanding an AI robot to do tasks differently leads to significant performance improvement in long-horizon, dexterous manipulation tasks without the need for any additional teleoperation. The experiment involved a robot scooping candy and cleaning plates. The researchers believe that creating a way of naturally interacting with AI robots and giving quick feedback is important. Humanoid robots are being developed to potentially replace humans in small businesses, as they don't require a salary and never take a day off.
