LabKate said:Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 39% to 19%.
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 = 4.7 (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.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 129 | 103 | 89 | 87 |
| Insulin (fasting) | 25 | 17 | 9 | 7 |
| HOMA-IR | 5.5 | 3.0 | 1.7 | 1.3 |
| Uric Acid | 7.7 | 6.9 | 5.6 | 5.0 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 5.5 to near 1.0 is a metabolic transformation.

Fasting insulin is the lab my functional medicine doctor cares about most for glycaemic control: it's a much earlier marker of metabolic dysfunction than glucose or A1C.
My fasting insulin: 28 → 14 → 5 uIU/mL over 9 months. Target is <7. By the time your fasting glucose is elevated, your insulin has been elevated for YEARS trying to compensate.
Ask your doctor to include fasting insulin in your bloodwork panel. It's cheap (~$20) and incredibly informative.

PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 10 months: periods became regular for the first time in years, testosterone levels normalized, acne cleared significantly, and — unexpectedly — I got pregnant naturally after 4 years of trying.
GLP-1 agonists address the insulin resistance at the root of PCOS. For PCOS patients, this isn't "just" a weight loss drug — it's treating our underlying metabolic dysfunction.
