Researchers studied 41 adults with type 2 diabetes, a condition that makes blood sugar harder to control. They compared one 30-minute daily walk with 10 minutes after each main meal.
Participants tried each routine for two weeks. Both meant the same daily walking time, but blood sugar after meals was lower with the three shorter walks.
The difference was largest after dinner, when participants ate the most carbohydrates, such as sugars and starches.
