What your number actually means
| HbA1c | What it indicates |
|---|---|
| Below 42 mmol/mol (below 6.0%) | Normal range |
| 42–47 mmol/mol (6.0–6.4%) | Prediabetes — raised risk, usually managed with lifestyle change and monitoring |
| 48 mmol/mol and above (6.5%+) | Diagnostic range for type 2 diabetes — your GP will discuss options with you |
Thresholds follow the ranges used across the NHS. Only your GP can interpret your result in the context of your full health picture.
The four levers that move it most
Put protein and fibre in front of your carbohydrate
Eating vegetables and protein before the starchy part of a meal produces a noticeably flatter glucose curve than eating the same food in the opposite order. Nothing is banned — the potatoes, rice or bread simply arrive later in the meal and in a smaller portion, alongside something that slows them down.
Shorten your eating window at the evening end
Insulin sensitivity falls as the day goes on, so the same bowl of pasta raises blood sugar more at 9pm than at 1pm. Finishing your last meal two to three hours before bed is one of the least disruptive changes you can make, and it often improves both fasting glucose and sleep.
Build a little more muscle than you have now
Muscle is where glucose goes after a meal. From your late forties onwards muscle is lost unless it is actively defended, which is why two or three short resistance sessions a week — bands, bodyweight, or a pair of dumbbells in the kitchen — do more for HbA1c than adding extra cardio.
Look honestly at the evening glass
Alcohol does not raise blood sugar much directly, but it fragments sleep, lowers next-day insulin sensitivity and quietly loosens food decisions. Many women see fasting glucose improve within a fortnight of moving from most nights to two or three nights a week.
Why the same effort works differently now
Two things change after menopause. Falling oestrogen reduces insulin sensitivity, so an identical meal lifts your blood sugar higher than it did in your thirties. And body composition shifts — fat is more readily stored around the middle, where it interferes with insulin signalling, while muscle quietly declines. This is why the advice that worked for a younger colleague can feel useless to you: it was never adjusted for a body with less oestrogen and less muscle.
General information, not medical advice, and no guarantee of any particular HbA1c result. If you take medication for blood sugar or blood pressure, speak to your GP or pharmacist before making significant dietary changes.
