Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
So the question, as narrowly as I can put it: why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Happy to be told the question itself is wrong.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 112 | 106 | 92 | 84 |
| Insulin (fasting) | 18 | 14 | 8 | 7 |
| HOMA-IR | 4.5 | 3.3 | 2.0 | 1.1 |
| Uric Acid | 8.0 | 6.2 | 5.9 | 4.8 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 4.5 to near 1.0 is a metabolic transformation.

Insulin sensitivity test (HOMA-IR) on glycaemic control — arguably the most important metabolic marker most people aren't tracking:
HOMA-IR = (fasting insulin × fasting glucose) ÷ 405
My numbers: Baseline HOMA-IR = 4.6 (insulin resistant) → Current = 1.0 (insulin sensitive)
Anything above 2.0 indicates insulin resistance. The goal is below 1.5. GLP-1 agonists address the root metabolic dysfunction, not just the symptoms. This is why they work so much better than calorie restriction alone.

Same experience, arrived at from the opposite direction. Posting only so the count is not one.
Adding the clinical framing, because it changes how the question reads.
Fasting insulin is the lab my functional medicine doctor cares about most for glycaemic control: it's a much earlier marker of metabolic dysfunction than glucose or A1C.
My fasting insulin: 22 → 14 → 5 uIU/mL over 9 months. Target is <7. By the time your fasting glucose is elevated, your insulin has been elevated for YEARS trying to compensate.
Ask your doctor to include fasting insulin in your bloodwork panel. It's cheap (~$20) and incredibly informative.
