Physical activity plays an important role, too

Exercise is essential to managing your blood sugar. Check with your doctor before starting a new physical activity, especially if you're taking medications that lower your blood sugar. People who have diabetes should aim for at least 150 minutes of moderate to vigorous activity each week. For example, aim to go on a brisk walk for about 30 minutes on most days of the week.

Drink water before, during and after activity to prevent dehydration. And be sure to wear comfortable, supportive shoes.
