If a recent report put your HbA1c somewhere between 5.7% and 6.4%, you have prediabetes. It is an uncomfortable label, and most people hear it as "you are on your way to diabetes."
That is the wrong reading. Prediabetes is the stage where your body is still listening.
What the number actually means
HbA1c estimates your average blood sugar over the previous two to three months. The usual reference points are:
- Below 5.7% — normal
- 5.7% to 6.4% — prediabetes
- 6.5% and above — diabetes
A fasting glucose of 100–125 mg/dL tells a similar story. Neither number means you are ill today. They mean your cells have started responding less efficiently to insulin, and the trend is heading in one direction.
Why this stage matters so much
The landmark Diabetes Prevention Program trial found that structured lifestyle change — modest weight loss and regular activity — cut progression from prediabetes to type 2 diabetes by roughly 58%. That was more effective than medication in the same trial.
Read that again: the intervention that worked best was not a drug. It was changing what people ate and how much they moved, consistently, with support.
For Indians this matters even more. South Asians tend to develop insulin resistance at lower BMIs and with more visceral fat than other populations, which is why a person who does not look overweight can still have a worrying HbA1c.
What actually moves the number
You do not need a dramatic overhaul. In practice, four things do most of the work:
- Change the shape of your plate, not your cuisine. Half the plate vegetables, a quarter protein, a quarter carbohydrate. Roti and rice stay — they just stop being the majority of the meal.
- Walk after you eat. Ten to fifteen minutes after your largest meal blunts the glucose spike that follows it. This is one of the highest-return habits available to you.
- Protect your sleep. Short sleep worsens insulin sensitivity within days. Seven to eight hours is not a luxury here; it is part of the treatment.
- Build some muscle. Muscle is where glucose goes. Two sessions of resistance work a week meaningfully improves how your body handles sugar.
Give it three months, then re-test
HbA1c reflects a rolling two-to-three month average, so there is no point re-testing in three weeks. Make the changes, hold them for twelve weeks, then measure again. Seeing the number move is what turns a chore into a habit.
A note on what we are
Preventians is a coach, not a doctor. We help you build and keep the daily habits that move these numbers, and we will always tell you when something belongs with your physician. Your prediabetes diagnosis, your medication, and your test schedule are conversations for your doctor. What happens at breakfast tomorrow is where we can help.
Prevent it. Reverse it.
