A1C went from 7.4 to 5.6 over nine months and my prescriber was more interested in the fasting insulin, which I did not expect.
What I actually want to know is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
I would rather have one careful answer than five confident ones.

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 35% to 18%. Target is <36%, with <30% being ideal.
Why this matters more than average glucose: large glucose swings cause oxidative stress, endothelial damage, and promote advanced glycation end-products (AGEs). A flat glucose line at 95 mg/dL is metabolically healthier than oscillating between 60 and 160, even if the average is the same.

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.

This matches mine closely enough to be worth saying so out loud.
Clinical perspective, offered as context rather than as advice.
My labs after 6 months on glycaemic control: A1C 6.3%, fasting glucose 88 mg/dL, fasting insulin 5 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 7.1% and fasting glucose was 123 mg/dL. The improvement has been dramatic and consistent.
