5. Exercise regularly.
No matter whether you have type 1 or type 2 diabetes, staying active can help bring down your A1C because activity makes your body absorb more sugar. If you’re type 2, exercise can help counteract insulin resistance by making your body more sensitive to it. Almost any form of exercise is good: walking, aerobic, strength training, or any combination of those. If you’re type 1, exercise when your blood sugar is high, 1 to 3 hours after you eat. If your blood sugar is low when you test it before you exercise, eat a snack before you start.
