Asprey applies the entrepreneur's metrics mindset to the body: if you track ROAS, website traffic, and podcast downloads, you should track thyroid, testosterone, and inflammation with equal seriousness. His Upgrade Labs facilities deliberately have no mirrors — 'your only mirror is your data' — to strip out self-deception and marketing-driven belief. He stresses you now have a right to your own data through direct-to-consumer blood panels and whole-body scans, without needing a doctor's gatekeeping. The key is to establish a baseline while you feel good, re-test over time, and act on what changes, treating biology as a managed variable of the business.
Origin
Asprey traces this to discovering in his 20s, after making millions building early data centers, that his testosterone was lower than his mother's — a fact that was very hard to uncover then and which convinced him everyone should own their biomarker data.
Core principles
- 01Manage your biology with the same rigor you manage business metrics like ROAS, traffic, and downloads.
- 02Data is the honest mirror — it removes self-deception and belief-based decisions about your health.
- 03You have a right to your own data and no longer need a doctor's permission to get it.
- 04Know your numbers even when you feel great, so you have a baseline to defend as you age.
- 05The three variables that matter most: thyroid (energy), testosterone (motivation), and inflammation (wasted effort).
How to run it
- 1
Adopt the metrics frame
Decide to manage your biology like a business dashboard, tracking thyroid for energy, testosterone for motivation, and inflammation for wasted effort.
Pro tip If you know your ROAS and download counts, you already have the discipline — point it at your body.
- 2
Get the data directly
Order an advanced longevity blood panel through direct-to-consumer services that draw blood at your home, without needing a doctor's sign-off.
Pro tip An advanced longevity panel runs a few hundred dollars — less than many entrepreneurs spend daily on ads.
Watch out A doctor may dismiss you as 'too young to test' — you have a right to your own data anyway.
- 3
Baseline while healthy
Capture your numbers when you feel great so you know where you function best and can restore that range as you age.
Pro tip Knowing your best-feeling levels at 27 lets you keep hormones there at 47.
- 4
Re-test and act on change
Repeat testing (and optionally an annual whole-body scan) over time and intervene only on the variables that actually move.
Pro tip With a whole-body scan you watch year-over-year change rather than panicking over a single congenital finding.
Watch out A one-time scan may flag something harmless; the value is in tracking whether it changes.
In the wild
In his 20s, after making $6 million building data centers that held early Google servers, Asprey discovered through hard-to-get testing that his testosterone was lower than his mom's.
→ The finding drove his conviction that everyone should own and act on their biomarker data early.
The founders of a whole-body scan company told Asprey a single podcast episode led perfectly healthy-looking listeners to get scanned, uncovering aneurysms and stage 3 cancers with no symptoms.
→ They credited the episode with saving 25 lives by surfacing silent, treatable conditions.
Common mistakes
Only testing when something is wrong
Without a healthy baseline you have nothing to compare against, so you can't tell what changed or restore your best-functioning levels.
Deferring to how you look or feel
Relying on the mirror, energy, or advertising instead of numbers lets self-deception and belief drive health decisions.
Is it for you?
Best for
Data-driven entrepreneurs already comfortable managing business metrics who neglect their own biomarkers.
Not ideal for
People prone to health anxiety who may spiral on ambiguous single-point results without guidance.

“At Upgrade Labs, your only mirror is your data. How am I actually doing? There's no self-deception.”
“If you know your ROAS, if you know the amount of traffic going to your website, how many downloads for your podcast, how dare you…”
“It's silly to run a business and not manage your biology.”
