Aging can feel like a passive process, one day you’re 25 and the next you’re receiving AARP letters in the mail. Taking control of your health gives you control of aging, especially when it comes to managing health conditions like diabetes. In this article, you’ll learn how diet and exercise are key parts of controlling your diabetes and lowering your hemoglobin A1C.
What is a hemoglobin A1C?
Often abbreviated HgA1C, this is a lab test that serves as a report card. Your HgA1C shows how your blood sugars have been over the past 3 months. This test can only be done every 3 months because that’s the average lifespan of your red blood cell! Sometimes in the hospital we will use your A1C to better see how your blood sugar has been. Illness, stress, diet changes, and other factors can make your blood sugar change, so using your A1C gives your healthcare providers a fuller picture!
What’s normal for me?
Your doctor and dietitian can look at trends for your A1C and develop a custom goal for you, but in
Support a healthy A1C with diet
Diet plays a huge role in blood sugar control. If you’ve never seen a Registered Dietitian, I suggest asking your doctor for a referral. Did you know only a handful of medical schools make doctors take nutrition courses? And when they do, they’re usually only 1-2 classes? Your dietitian can give you specific goals and even a meal plan to help control your blood sugar.
You need “good” carbs
A common myth we hear from people with diabetes is to avoid carbs. If I had a neon sign, this is where I’d put it! Carbs give our brain, muscles, and cells energy. You need carbs! The key is to look at your sources of carbs, and to keep the amount consistent throughout the day.
That’s right, eat carbs!
Aim for 4-6 servings of carbs (60-76 grams of carbs) at each meal.
The carbs I want you to focus on

So, if one serving of carb is 15 grams of carbohydrate, aim for 4 items per meal from this list per meal. This surprises people, it can seem like a lot of carbs. But a diet full of vegetables, fruit, whole grains and good quality fats will help control your blood sugar and bring your A1C down.

Think of it as a 3-month challenge, see how many points you can drop your A1C before your next lab draw!
Adding exercise for blood sugar control
Adding exercise helps decrease your blood sugar. If you are on insulin, ask your doctor how to regulate your sugar before exercise. Exercise and muscle movement shuttles sugar into your tissues and muscles for energy, lowering the amount in your blood!
Start slow, but just go!
If you are sedentary, try adding small amounts of exercise each day. No gym, no problem! Take the stairs instead of the elevator, park further away from the supermarket, or try using a standing desk at work. Once you are comfortable with these changes, try going on a 20-30 minute walk each day. Pairing a consistent carb diet with exercise can help control your diabetes and lower your A1C!
