Insulin: The Aging Accelerator
Insulin is the master switch
Chronically elevated insulin drives fat storage, inflammation, and activates mTOR — the growth pathway that accelerates aging. Insulin sensitivity may be the single best longevity biomarker.

HOMA-IR — the test you should ask for
HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) uses fasting glucose × fasting insulin ÷ 405. Below 1.0 = insulin sensitive. 1.0–2.0 = average. Above 2.0 = resistance brewing. The test is cheap and most labs run it; HbA1c misses early resistance because glucose looks fine while insulin's working overtime.

Key Takeaway
Keep insulin low and sensitivity high: eat whole foods, walk after meals, practice time-restricted eating, and build muscle.
