An analysis has found that engaging in light exercise within 15 minutes after a meal can reduce the rise in blood glucose levels.

On August 26, HLB Lifecare, a subsidiary of HLB Global, analyzed user data from the 'MyPicoRing' app, which syncs with the continuous glucose monitor (CGM) 'PicoRing.' The results showed that users who exercised within 15 minutes after eating experienced an average blood glucose increase that was 33% (16.8 mg/dL) lower than that of users who did not exercise. The analysis utilized data from over 20,000 actual user meal records stored on the service, focusing on records involving 47 foods commonly consumed by Koreans.

There was also a notable difference in the incremental area under the curve (iAUC), which represents the duration of elevated blood glucose exposure over three hours after a meal. The average iAUC for users who did not exercise was 3,681, whereas the group who exercised within 15 minutes after a meal showed a figure of 2,242, indicating a reduction of approximately 39%. An additional analysis comparing instances of the same individual consuming the same food showed that light exercise within 15 minutes after a meal reduced the average blood glucose increase by 11.5 mg/dL and the average iAUC by 864.

In an actual case, a female user in her 30s saw her blood glucose rise by 70.7 mg/dL when resting after eating fruit, but only by 24 mg/dL when she engaged in light exercise within 15 minutes of eating the same food. The iAUC also decreased by approximately 76%, from 4,526 without exercise to 1,068 after exercise. Similarly, a male user in his 40s performed light indoor walking within 15 minutes of eating a Korean set meal and recorded an iAUC of 1,196—about 67% lower compared to the non-exercise group average (3,681).

Cheolwoo Ahn, Professor of Endocrinology at Gangnam Severance Hospital, said, “Recently, the importance of real-time blood glucose monitoring has been increasingly emphasized not only for diabetes but also in managing metabolic syndrome. This analysis is interesting because it demonstrates that, beyond simply eating less, when and how you move can be effective in reducing blood glucose variability.”
