Taking time out for a walk after three meals every day helps to control blood sugar. American researchers have found that walking at a speed of 3 kilometers per hour for at least 15 minutes after a meal can reduce the risk of rapid rise of blood sugar after a meal. If busy urbanites don't have time to do exercise, it is found that doing it three times 15 minutes respectively is more effective in preventing diabetes than doing 45 minutes of continuous exercise in the morning or at noon.

A study conducted by the School of Public Health of the University of Washington, Georgia invited 10 high-risk diabetic patients with an average age of 60. Although their blood sugar did not exceed the standard, their blood sugar increased after meals. They run on the treadmill for 45 minutes in the morning 10: 30 or at 4: 30 noon, or walk for 15 minutes after breakfast, lunch and dinner, with moderate exercise, and monitor the changes of blood sugar with instruments throughout.

The results show that morning exercise has little effect on improving the soaring blood sugar after meals, and afternoon exercise is useful for controlling blood sugar all day, but the effect is not as obvious as walking after meals. The study also found that walking 15 minutes after meals is the key to improve hyperglycemia, because after eating a rich dinner, if you sit still, your blood sugar will not only rise rapidly after meals, but also fluctuate in the next 24 hours, so walking after meals can stabilize your blood sugar in a short time.

The researchers pointed out that the speed of walking kilometers per hour requires very low physical strength, which is especially suitable for people who cannot exercise for a long time. For example, the elderly and pregnant women with insufficient physical strength are suitable for exercising in this segmented way.
