Postprandial walk may improve blood glucose levels

A study of 10 individuals aged around 70 with higher than normal fasting blood glucose levels found 15 minutes on a treadmill at an easy-to-moderate pace after each meal was as effective as one daily 45-minute walk at regulating postprandial glycaemia.

Importantly, walking after the evening meal blunted the usual spike in blood sugar, which can persist overnight.

The intervention was practical, the researchers said, as it could be combined with daily errands or walking the dog.
