The Die Pie — What Share of People Actually Treat Their Body Deliberately
How deliberately does the population actually treat the body? Four tiers, drawn to scale.
Everyone is somewhere on this chart. Most people are on the default trajectory — not by choice, but by not choosing. Each tier up is a smaller, more deliberate slice, and the cost of entry rises fast. The last one is a sliver you can barely draw.
The interesting number is not the big slice. It is that 97.3% of adults never get past “moderately healthy” — and that the gap between tier 2 and tier 3 is not effort, it is deliberateness. Tier 2 is someone who goes to the gym. Tier 3 is someone who has made a decision about their cookware, their detergent, their fabrics and their water. Almost nobody crosses that line.
Share of adults by tier
Segments drawn to true angle — no scale breakGo with the flow
Mostly processed food, alcohol on a regular basis, short sleep, largely sedentary, polyester and synthetics, takes whatever the doctor prescribes without a second opinion.
73.6% of US adults do not meet both the aerobic and muscle-strengthening activity guidelines — the inverse of the 26.4% who do. CDC / NCHS, 2024.
Casually healthy
Exercises regularly, eats moderately well, and is mostly under 50 — the age band where meeting the guidelines is roughly twice as common as it is past 65.
26.4% meet both activity guidelines (32.1% among 18–44), minus the 2.7% who also clear every healthy-lifestyle criterion.
Deliberately clean
Exercises, uses non-toxic products, wears natural fibres, takes bioavailable supplements daily, and eats mostly fresh or organic. Every one of these is a purchase decision made against the default.
2.7% of US adults meet all four healthy-lifestyle characteristics at once, minus the longevity-protocol subset above. Mayo Clinic Proceedings, 2016.
Longevity protocolEstimated
Everything in tier 3, plus regular hyperbaric oxygen, red light, sauna and cold exposure. Roughly 1 person in 200 — a 1.8° slice of the circle.
Derived, not published: ~3% report regular biohacking-tool use, but only a fraction of those also run the full tier-3 stack.

How each boundary was set
Three of the four boundaries come straight from published surveys. They are stitched from separate studies taken in different years, so treat this as a considered composite rather than a single piece of fieldwork.
- Tier 1 / 2 — 26.4%. US adults meeting both the aerobic and muscle-strengthening guidelines in leisure time, 2024 National Health Interview Survey. Highest at 32.1% among 18–44, which is why tier 2 skews under 50. CDC / NCHS
- Tiers 3 + 4 — 2.7%. Adults meeting all four healthy-lifestyle characteristics at once: good diet, sufficient activity, healthy body-fat percentage, non-smoker. Loprinzi et al., Mayo Clinic Proceedings, 2016. PubMed
- Tier 4 — ~0.5%, estimated. Around 3% of adults report regular use of biohacking tools and 18% have tried sauna, cold plunge, red light or cryotherapy. Most of them are not also running the full tier-3 stack, so the overlap is smaller than either figure.
- Tier 1 behaviours. 53.0% of adult calories come from ultra-processed foods; 30.5% sleep under seven hours; 62% drank alcohol in the past year. Supplement use is not a tier marker — 60.2% of adults take one. NCHS
Companion pieces: The Personal Power Pie asks whether the thinking is yours at all, and the Cognitive-Motivational Bias Matrix sets out the structure of systematic error that it measures against. Sleight of Mouth is the conversational tool for taking one of those beliefs apart.
On the one estimated figure. No survey measures “does the full clean-living stack and runs longevity protocols”, so the 0.5% is an estimate of the overlap between two measured groups rather than a published number. It is the right order of magnitude, not a fact — and it is flagged as such on the chart itself.
