Exercise (such as 20 min of walking) has an acute beneficial impact on postprandial hyperglycemia when undertaken as soon as possible after a meal.

Longer intervals between eating and exercising weaken the acute effect on glucose levels.

Exercise prior to a meal does not blunt postprandial hyperglycemia.

Post-meal exercise minimizes glycemic excursions and therefore might lower the risk for low-grade inflammation diseases and cardiovascular diseases.
