How NOT to Start a Longevity Clinic

Longevity medicine is becoming exceptionally good at measuring things.

We can scan body composition, estimate cardiorespiratory fitness, sequence genes, track glucose, interrogate sleep and produce several competing versions of biological age. Given a quiet afternoon and enough blood, the modern clinic can generate a truly magnificent PDF.

Changing what happens next is harder.

David Luu's conversations with physicians building longevity practices point to some wonderfully ordinary lessons: do not buy expensive equipment before there is demand, do not offer every service at once, and do not mistake a consultation for a system of care.

But suppose your ambition is different. Suppose you want to build a clinic that looks like a spacecraft, produces an almost spiritual quantity of data and changes very little.

Here is the plan.

1 Buy the equipment first

Start with the DEXA scanner. Add a metabolic cart, a body-composition machine, a red-light room and anything with enough brushed aluminium to suggest that ageing has finally met its match.

Only later should you ask whether enough patients need the test, whether the team can interpret it consistently or whether the result changes a decision.

A machine is not a care model. It becomes useful when its information changes an intervention, a priority or a follow-up conversation. Until then, you may simply have bought extremely persuasive furniture.

2 Measure everything. Then measure it again.

Order ApoB, genetics, a microbiome panel, continuous glucose monitoring and several biological-age tests that disagree just enough to justify another appointment.

Give the patient 147 biomarkers, six portals and a low-grade fear that breakfast has become a medical event.

The sensible question is not, “Can we measure this?” It is, “What decision will this measurement change?” Testing can be valuable when it is clinically appropriate and interpreted in context. Testing without a decision attached is mainly a sophisticated way to collect PDFs.

Perhaps leave some blood in the patient.

3 Major in the minors

Debate the second decimal place of biological age while ignoring the fact that the patient is breathless on the stairs.

Study whether blueberries create a tiny glucose excursion, but do not ask whether the person can squat comfortably, carry shopping or get off the floor. Optimise the exact minute of morning sunlight while bedtime remains 1:30 a.m.

Complexity can be a very elegant form of avoidance. It lets everyone feel advanced without having the awkward conversation about sleep, strength, movement, smoking, food or the plan that has not been followed.

Before discussing cellular reprogramming, ask whether the patient can climb the stairs.

4 Tell people to exercise

Tick the box marked “exercise discussed” and move briskly on.

Do not ask about mobility, strength, endurance, balance, pain, confidence, schedule or access. Do not translate the recommendation into something the patient could actually do on Tuesday.

Walking is free, which is commercially inconvenient. Squats cannot be patented. Balance training does not arrive by refrigerated courier. A progressive strength plan over five years is less exciting than a peptide on Instagram.

So prescribe exercise, preferably from under a desk.

In real care, exercise advice should be appropriate to the individual, their health, function and clinical circumstances. “Exercise more” is not yet a programme.

5 Discover the secret of longevity. Again.

The secret may be resveratrol, metformin, NAD, rapamycin, senolytics or peptides. Some are scientifically interesting. Some may prove useful for particular people in particular circumstances. None excuses a clinic from doing the less glamorous work.

The peptide has entered the chat. The patient has not entered the gym.

The foundations remain stubbornly familiar: movement, strength, sensible eating, sleep, not smoking, relationships and management of known risks. The frontier matters. It just should not be confused with the foundation—or offered without appropriate clinical assessment, evidence and monitoring.

6 Give people a beautiful plan. Then disappear.

Run the tests. Deliver the 90-minute explanation. Produce a 14-page plan with impeccable typography. Invite the patient back next year.

This is an efficient way to make the consultation the climax of care, just before ordinary life begins dismantling it.

The useful unit is not the appointment. It is the loop:

Measure → Prioritise → Act → Follow up → Learn → Adjust → Repeat

An ordinary intervention sustained for nine years is likely to matter more than a brilliant one sustained for nine days. The patient eventually goes home, which is where the design problem starts.

7 Definitely do not hire a health coach

Doctors should not spend their days checking whether someone walked four times last week. That does not mean nobody should.

Clinical judgement remains clinical. Diagnosis, treatment and consequential decisions belong with appropriately qualified practitioners. Behaviour change, education, accountability, reminders, progress reviews and translating an approved plan into daily life are different kinds of work.

A clinic that owns only the appointment has episodic care with better branding.

Coaching does not replace medicine. Done properly, it can help people understand and follow a clinician-approved plan, notice obstacles and bring useful information back for review.

8 Avoid measurable targets

Recommend better sleep, more exercise, less stress, improved nutrition and optimal metabolic health.

At the next annual review, agree that the patient is probably more optimised.

A useful plan needs a starting point, a destination and a review date. Not everything important can be reduced to a number, and no metric should be interpreted without context. But selected measures—such as blood pressure, relevant laboratory markers, strength, fitness, function or adherence—can help clinician and patient see whether the plan is working.

Without feedback, personalised medicine is often personalised advice.

9 Make the patient the project manager

Provide six PDFs, three apps, a supplement schedule, a wearable and four referrals. Expect the patient to integrate the information, reconcile contradictions, arrange the appointments and remember what everyone said.

If the system collapses, record “poor adherence”.

Most people do not want another job. A practical care plan identifies the few feasible actions most likely to matter, makes ownership clear and keeps the relevant context together. Five interventions completed at 20 per cent are not automatically better than one completed at 90 per cent.

A plan that requires the patient to become their own doctor, nutritionist, personal trainer and administrative assistant is not much of a plan.

10 Confuse information with care

Collect labs, wearables, imaging, genetics, questionnaires, records, lifestyle data and an AI-generated summary of the other summaries.

Assembly is not care.

Information becomes useful when it changes what happens next:

Fragmented information → Context → Priorities → Action → Measurable progress → Review

Technology can help organise evidence, maintain continuity and surface what deserves attention. It should not quietly replace clinical judgement, invent certainty or turn the length of a report into the measure of success.

The clinic has extended the report by 37 pages. The patient's healthspan remains under review.

The future of longevity care may include extraordinary technology. It should. But a clinic that measures everything and changes nothing is merely an expensive way to document ageing.

When a patient leaves, the useful questions are less glamorous:

• Do they understand what matters?
• Do they know what to change first?
• Is the plan realistic in their life?
• Will someone notice whether it worked?
• What happens when it does not?

Your biological age can wait. What did you actually change?
