GLP-1 and beta-cell preservation — looking for input

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 38% to 21%.

Patient selection optimization for glycaemic control: emerging predictive biomarkers for GLP-1 agonist response include:

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.

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 6 months on glycaemic control: A1C 5.1%, fasting glucose 76 mg/dL, fasting insulin 5 uIU/mL. My endo says these are "textbook perfect."

For context, my baseline A1C was 6.7% and fasting glucose was 111 mg/dL. The improvement has been dramatic and consistent.

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.

Following on from PharmD_Rodriguez — and this may be the naive question:

Did your prescriber agree with that reading, and if not what was their objection?

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 = 6.1 (insulin resistant) → Current = 1.1 (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.
