If your A1C came back at 5.7, 6.0, or 6.3%, you may feel completely normal.
That is common.
Prediabetes and type 2 diabetes often develop without obvious symptoms. For a lot of people, the bloodwork is the first sign that something has started to change.
That number deserves attention. It does not tell you everything about your health, and it does not tell you what the next six months have to look like.
What A1C measures
A1C is a blood test that estimates your average blood glucose over roughly the previous three months. It measures the percentage of hemoglobin in your red blood cells that has glucose attached to it.
The commonly used diagnostic ranges are:
- below 5.7%: normal range;
- 5.7% to 6.4%: prediabetes range;
- 6.5% or higher: diabetes range.
A1C is still one test. If you do not have symptoms and a result falls in the prediabetes or diabetes range, your healthcare professional may repeat the A1C or use another blood-glucose test to confirm what is going on.
Some medical conditions and circumstances can also affect A1C accuracy. That interpretation belongs with your healthcare team.
Why the number matters when you still feel fine
You can still be working, raising kids, running errands, and handling a normal schedule while your blood glucose has been running higher than it used to.
That is one reason appearance alone does not tell me enough about someone’s metabolic health.
What I would look at next
If a parent came to me with an A1C in the prediabetes range, I would start with the week they are already living.
- How much are they moving outside workouts?
- Are they doing regular strength training?
- What does breakfast look like on a workday?
- How much protein are they getting?
- What usually happens at dinner?
- Are weekends completely different from weekdays?
- How much sleep are they getting?
- What has body weight or waist measurement been doing when fat loss is appropriate?
Then I would look for the few changes that can survive a normal week.
The prevention evidence favors repeatable lifestyle change
The Diabetes Prevention Program studied people at high risk of developing type 2 diabetes. Participants in the intensive lifestyle group worked toward about 7% weight loss and at least 150 minutes of physical activity per week.
Over about three years, that group had a 58% lower incidence of developing type 2 diabetes compared with the placebo group.
The useful takeaway is broader than one workout or one food rule.
Where strength training fits
Current adult activity guidance includes regular aerobic activity plus muscle-strengthening work. The American Diabetes Association also recommends resistance training two to three times per week on nonconsecutive days for adults with diabetes.
That does not let us promise a specific A1C drop from lifting. It gives us another reason to build strength into the week alongside walking, nutrition, sleep, and medical care.
Food has to work in your house
Advice for prediabetes often gets reduced to “eat better.” Most parents already know that.
The harder part is Tuesday night when somebody has practice, dinner is late, and you have twenty minutes. I would rather adjust the meal you already make than build a nutrition plan that requires a second kitchen.
Do not judge the whole plan from one number
Your next A1C is useful feedback. I also want to know what changed during those months.
Did you get stronger? Become more active? Lose excess weight when appropriate? Build meals that are easier to manage?
A good lab result followed by a return to the same routine does not solve much.
Your A1C is giving you information. Build a week you can actually repeat.
