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 = 5.9 (insulin resistant) → Current = 1.5 (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.

A narrower follow-up, since the general answer is now clear:

What would you measure differently if you were starting again?

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.

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.

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.
