There is an enormous amount of interest today in longevity. Supplements, peptides, red light therapy, cold plunges, NAD+, rapamycin, nitric oxide boosters, continuous glucose monitors, biological-age testing, and an ever-growing list of technologies and interventions are marketed as ways to help us live longer or age better.
Some of these ideas are scientifically interesting. A few may eventually prove useful. Many are supported by far less evidence than the marketing surrounding them would suggest.
But there is a more fundamental problem with starting there.
Longevity should be the last thing we address, not the first.
The way I approach men’s health and preventive medicine is built around three interconnected levels: Health, Wellness, and Longevity. I think of them as a pyramid. Health forms the foundation. Wellness sits on top of health. Longevity sits at the top.
You cannot build the top of the pyramid before establishing the foundation underneath it.
Health Comes First
The first question is not, What can I take to live longer?
The first question is much simpler: Are you actually healthy?
That question is more difficult to answer than most people realize.
A man may exercise regularly, maintain a reasonable body weight, eat relatively well, and feel perfectly healthy. Those are all important. But they do not necessarily tell us what is happening beneath the surface.
You can look healthy and still have significant coronary atherosclerosis. You can exercise and still have hypertension, insulin resistance, abnormal lipoproteins, sleep apnea, low skeletal-muscle reserve, metabolic dysfunction, or an important hormonal abnormality. Some of the most consequential diseases remain silent for years before producing symptoms.
Looking healthy and being healthy are not always the same thing.
That is why the first part of the process is an objective, comprehensive preventive health assessment. We need to understand cardiovascular risk, metabolic health, body composition, blood pressure, sleep, hormone health, physical capacity, mental health, and the other major variables that influence disease risk, healthspan, and long-term function.
This is the foundation.
If we identify hypertension, we address it. If someone has substantial atherosclerotic cardiovascular risk, we reduce that risk. If he has untreated sleep apnea, we treat the sleep apnea. If he has poor metabolic health, inadequate muscle mass, or another meaningful medical problem, those issues take priority.
There is little value in debating whether a supplement might improve lifespan by some theoretical amount while ignoring a major cardiovascular risk factor that we already know how to treat.
Then Comes Wellness
Once the major health issues have been identified and appropriately addressed, the next level is wellness.
This is where lifestyle becomes much more deliberate and individualized, and where wellness planning becomes an ongoing process of improving health, function, and physiologic reserve.
Exercise
Telling someone to “exercise more” is not much of a prescription. We want to know whether he is performing enough resistance training to preserve muscle and strength, whether he is developing adequate aerobic capacity, whether he is incorporating appropriate Zone 2 work, and whether his training actually matches his current physiology and goals.
Nutrition
Nutrition works the same way. “Eat healthy” is vague. Protein requirements, total energy intake, body-composition goals, metabolic status, training demands, and age all matter. The nutritional strategy that is appropriate for one person may be completely wrong for another.
Sleep
Sleep also becomes something we deliberately optimize rather than simply asking whether someone gets eight hours. Sleep duration, sleep quality, sleep hygiene, circadian habits, and the presence of disorders such as obstructive sleep apnea all matter.
Building Physiologic Reserve
Wellness is therefore about taking the person whose medical foundation we have established and asking: How do we help this individual function better?
How do we preserve muscle? Improve cardiovascular fitness? Maintain mobility? Improve sleep? Support metabolic health? Reduce visceral fat? Maintain cognitive and physical performance? Build enough physiologic reserve that illness, injury, or aging has less ability to knock him down?
These are some of the fundamental components of health optimization and extending healthspan, the years of life spent in good health and with meaningful physical and cognitive function.
These interventions are not glamorous, but they are where much of the meaningful work occurs.
Longevity Comes Last
Only after health and wellness have been addressed does it make sense to talk seriously about the third level: longevity medicine.
This is where we can evaluate the emerging interventions that receive so much attention.
Could a medication such as sirolimus eventually prove capable of slowing aspects of human aging? Possibly. Are there supplements or technologies that may provide small additional benefits in appropriately selected people? Perhaps. There is legitimate and fascinating science taking place in aging biology.
But this area also contains extraordinary amounts of speculation, premature extrapolation, and marketing.
An intervention may improve a molecular pathway in a mouse or alter a biomarker in humans without demonstrating that it meaningfully extends human life or healthspan. Biological plausibility is interesting, but it is not the same thing as a clinically meaningful outcome.
That does not mean we should ignore emerging longevity science. It means we should put it in the proper place: at the top of the pyramid.
Once someone’s cardiovascular risk is controlled, metabolic health is good, blood pressure is optimized, sleep is addressed, body composition is appropriate, skeletal muscle and aerobic capacity are being deliberately maintained, and the major components of health and wellness are in place, then we can reasonably ask whether anything else might provide an incremental benefit.
At that point, the conversation also becomes much more rational. We can look at the evidence behind a particular intervention, its risks, its cost, the magnitude of any plausible benefit, and whether it is worth pursuing.
Sometimes the answer will be yes. Frequently, the answer will be that the evidence simply is not there yet.
Build the Pyramid in the Right Order
The longevity industry has a tendency to reverse this process. It sells people the top of the pyramid first because the top is exciting.
The foundation is less exciting.
Checking blood pressure is not exciting. Treating sleep apnea is not exciting. Lowering atherogenic lipoproteins is not exciting. Building skeletal muscle three days a week for the next 20 years is not particularly novel. Neither is maintaining aerobic fitness, eating enough protein, avoiding obesity, controlling glucose, sleeping consistently, or not smoking.
But these are precisely the things for which we have the strongest evidence.
There may eventually be therapies that substantially alter the biology of human aging. I hope there are. When convincing evidence emerges, we should use it.
Until then, longevity medicine should begin with medicine.
First, establish health. Then optimize wellness. Finally, explore longevity.
That is the order because each level depends on the one beneath it. And if the foundation is weak, no supplement, device, peptide, or longevity technology can compensate for it.
This Health–Wellness–Longevity framework is the foundation of how I approach men’s preventive health, wellness management, and longevity medicine at The Men’s Clinic for Wellness & Vitality in Tucson, Arizona.
