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.

My labs after 3 months on glycaemic control: A1C 5.4%, fasting glucose 79 mg/dL, fasting insulin 8 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 7.3% and fasting glucose was 114 mg/dL. The improvement has been dramatic and consistent.

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 41% to 21%. 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.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.

From the other side of the consultation, briefly.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:

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.
