Fasting insulin normal range by age: useful zones, not one universal cutoff
Fasting insulin ranges by age, with practical zones for HOMA-IR, lab reference intervals, repeat testing, and safer metabolic trend interpretation.
How often should you measure biological age? Retest timing by clock type
How often to measure biological age, retest cadence by clock type (DunedinPACE, PhenoAge, KDM), blood markers, and the case for wearable tracking.
Perimenopause and biological age: which markers change before menopause
Perimenopause shifts your biological age years before your final period. Learn which biomarkers move first, how to track them, and what changes mean.
Biological age plateau: why your score stops improving
Your biological age score has stopped improving. Here's why plateaus happen, how to diagnose them, and which levers actually restart progress.
Body recomposition and biological age: can your score drop while the scale stays the same?
Learn how body recomposition can lower biological age by reducing visceral fat, building muscle, and improving biomarkers even when weight stays stable.
Shift work and biological age: how night work accelerates aging
Shift work raises biological age acceleration and CVD mortality. See how night and rotating schedules age you faster — and what actually helps.
Strength training vs cardio for biological age: which lowers it more?
Does strength training or cardio lower biological age more? Epigenetic clock data, telomere studies, and a head-to-head comparison of how each modality moves your aging biomarkers.
Biological age vs vascular age: which age metric matters most?
Biological age and vascular age sound similar — but they measure different things. Here's how they compare, when each matters, and which to track.
Biological age vs fitness age: what is the difference and which one matters more?
Biological age vs fitness age: learn how whole-body aging differs from cardio fitness age, why the numbers can disagree, and how to track both.
