What Does ‘Optimizing Your Health’ Actually Mean?

I've been running since high school — 3,000 meters on the track back in Canada, then road running through medical school, residency, fellowship, and 20 years of clinical practice across several cities. There's something about the consistency of it that I find useful. It gives me a baseline for how my body is responding to everything else in my life: sleep, stress, travel, the periods when I'm training deliberately versus just maintaining.
What I've noticed over two decades — and what I've watched in patients — is that “feeling fine” and “functioning well” are not the same thing. Many people arrive at a serious health event after years of being technically fine on every standard metric while the underlying trajectory was quietly moving the wrong direction. Standard medicine doesn't pick this up because it's not designed to. It's designed to catch disease after it crosses a threshold, not to track trajectory.
That's what health optimization is supposed to address. The term has been used in enough different ways that it's worth being precise about what it means at its best — and where it goes wrong.
The Gap Between “Disease-Free” and “Functioning Well”
Modern medicine's core model is reactive: symptoms appear, evaluation follows, treatment targets the diagnosis. The goal is restoration to clinical norms — blood pressure below X, cholesterol within range, glucose not in the diabetic range. This is valuable and it saves lives. It is also, by definition, backward-looking.
A person can be entirely disease-free on every standard check — no diagnoses, all labs in normal range — and still be heading toward a cardiovascular event ten years from now, with fasting insulin creeping up, testosterone declining gradually, hs-CRP sitting persistently elevated, and VO2 max dropping toward a level that will predict functional decline in older age. Standard annual preventive care does not catch this. It isn't designed to.
Health optimization, at its best, is the systematic project of identifying where that trajectory is heading and intervening before it arrives at disease.
What the Evidence Supports
Advanced biomarker assessment. Beyond basic lipid panels and glucose, markers like ApoB, Lp(a), small dense LDL particle number, fasting insulin, HOMA-IR, and hs-CRP provide meaningful cardiovascular risk information that standard panels miss. These aren't exotic tests — they're well-validated, available, and actionable. They're just not standard practice because standard preventive care wasn't designed around them.
Physical performance as a longevity metric. VO2 max is among the strongest predictors of long-term mortality available to clinicians. A 2018 analysis in JAMA Network Open found that men in the lowest VO2 max quintile had all-cause mortality rates roughly 5 times higher than those in the highest quintile over a median 8-year follow-up (Mandsager et al., 2018).[1] The effect size rivals or exceeds most pharmacological cardiovascular interventions in primary prevention. Measuring and actively improving cardiorespiratory fitness isn't an athletic luxury — it's longevity medicine with better evidence than many things routinely prescribed.
Longitudinal biomarker tracking. A single measurement tells you where you are. A series over years tells you where you're going. Testosterone that has declined 25% over three years, fasting insulin trending upward while still in normal range, free T3 consistently at the low end of normal — these patterns tell a clinical story that a cross-sectional snapshot cannot.
Genetic information. Your genome doesn't change. Variants affecting lipid metabolism (PCSK9, LPA), drug metabolism (CYP2D6, CYP2C19), or hereditary disease risk (BRCA, Lynch syndrome) are actionable long before any disease develops. This information changes what you monitor, how aggressively you intervene, and sometimes what you prescribe — whether or not any diagnosis currently applies.
Where Health Optimization Goes Wrong
The term carries enough commercial momentum that the problems are worth naming explicitly.
“The strongest interventions for a longer, healthier life remain vigorous exercise, quality sleep, not smoking, maintaining metabolic health, and close management of cardiovascular risk. None of this is commercially exciting. All of it is supported by decades of robust evidence.”
Supplement maximalism. Most of what is sold as 'health optimization' in the supplement market rests on animal data, mechanistic plausibility, or underpowered human studies rather than rigorous outcomes trials. A short list of supplements has meaningful evidence in specific contexts. The long list promoted across wellness platforms generally doesn't. Taking things based on hope rather than evidence isn't optimization — it's experimentation at your own expense.
Treating numbers rather than patients. A testosterone level in the lower quartile of normal means something different in a symptomatic 50-year-old than in a 40-year-old who feels excellent. Aggressive pharmaceutical intervention for every number at the low end of a reference range is not precision medicine — it's a commercial model that conflates testing with treatment.
Unproven interventions marketed as established. Rapamycin, exogenous NAD+ precursors, senolytics — these are genuine areas of scientific interest with preliminary human data. They are not established therapies. A practice that recommends them routinely is working ahead of the evidence, which is a real risk with real potential consequences.
The Practical Version
Health optimization worth taking seriously involves building a comprehensive picture of where someone is — the things working well, the things drifting in the wrong direction, and the risk factors that haven't become diagnoses — and then making evidence-grounded decisions about what to address, when, and with what level of intervention.
It requires a physician who can distinguish between what the evidence supports and what is being marketed, and who is willing to be honest about both in the same conversation. And it requires the patient to do most of the work outside of clinical encounters — because no supplement, panel, or device substitutes for the fundamentals.
The goal is not a perfect set of numbers. It's a longer, more capable life. Those are related but not the same thing, and the difference matters.
