Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
The question I want answered is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Practical detail welcome, however dull — the duller the better.

Patient selection optimization for glycaemic control: emerging predictive biomarkers for GLP-1 agonist response include:
| Biomarker | Association | Evidence Level |
|---|---|---|
| Baseline BMI | Higher BMI → greater absolute weight loss | Strong |
| Fasting insulin | Higher insulin → better response | Moderate |
| GLP1R gene variants | rs6923761 → variable response | Preliminary |
| Baseline hsCRP | Higher CRP → greater CV benefit | Moderate |
| Early weight loss (4 wk) | ≥3% at 4 wks → strong predictor of ≥10% at 68 wks | Strong |
The 4-week early responder criterion is the most clinically actionable: if you haven't lost ≥3% by week 4 at a therapeutic dose, discuss optimization strategies with your provider.

My labs after 9 months on glycaemic control: A1C 6.2%, fasting glucose 77 mg/dL, fasting insulin 4 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 6.9% and fasting glucose was 122 mg/dL. The improvement has been dramatic and consistent.

This is my experience too, for whatever a second data point is worth. Nothing to add that would improve it.
From the other side of the consultation, briefly.
Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 122 | 108 | 90 | 86 |
| Insulin (fasting) | 18 | 16 | 10 | 6 |
| HOMA-IR | 4.5 | 3.8 | 1.8 | 1.1 |
| Uric Acid | 8.5 | 6.2 | 5.7 | 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.
