The four levers that move healthspan

There is a version of longevity medicine that is mostly about peptides and protocols, and it sells well because it is interesting. The trouble is that it is built on top of a foundation most people have not laid.

Lasting health rests on nutrition, movement, sleep, stress and the load on your body from what it has been exposed to. Get those in order and the advanced work has something to act on. Skip them and you are paying a great deal of money to compensate for six hours of bad sleep.

Nutrition

Not a diet. A pattern you can hold for twenty years without thinking about it, built mostly from food that did not require a label.

Testing is useful here because it moves the conversation off ideology. What your own metabolic markers do in response to how you actually eat is a fact, and it settles arguments that no amount of reading will.

Movement

Two separate things get called exercise. One is cardiovascular capacity, which tracks with how long you live better than almost anything else we can measure. The other is strength, which tracks with whether the last decade of your life is spent independent.

Most people over fifty are undertrained in the second one and know it. Strength responds at any age, which is not true of everything.

Sleep

Sleep is where repair happens, and there is no supplement that substitutes for it. If you are sleeping six broken hours a night, that is the finding, and working on anything else first is a way of avoiding it.

Circadian timing matters alongside duration. Light in the morning, dark at night, and a consistent schedule do more for most people than anything they could buy.

Stress and load

Chronic stress is not a mood. It is a hormonal state with measurable downstream effects, and it is the lever people are most reluctant to pull because pulling it usually means changing something about their life.

Alongside it sits toxin burden, which is the accumulated load from what you have breathed, drunk and lived in. It is testable, it is often reducible, and it rarely comes up in a fifteen minute appointment.

Then, and only then, the rest

Once the foundation is in place, advanced work has a job to do, and the testing tells us which of it is worth your money. Targeted supplementation where a deficiency exists. Support for the specific system your own results say is struggling.

Anyone who sells you the advanced work before the foundation is selling you something. Ask why.
