On the same shelf
One book for the whole body
Most books on evolution and health take one slice: food, breath, exercise, metabolism. Spiral Staircase covers the whole body and the mind, and for every part asks the same four questions: what did it evolve to expect, what does it get now, what happens in the gap, and what should you do about it?
Every part of you was shaped for a particular world. Feet for uneven ground. Eyes for daylight at a distance. A gut for dirt and fibre. A stress response for short, sharp danger and long recoveries. A mind for a village of people who knew your name. Health advice usually starts from the symptom. This book starts from the design: work out what each system was built to expect, and you have a specification for the conditions it needs to thrive.
That is the thread through all 16 chapters, and as far as we can find no other book follows it across the whole body and mind. The science books tell the evolutionary story and stop short of personal advice. The practical books give advice for one system. This one does both, system by system, and grades every recommendation so you know which to act on first.
The same four questions, for every system
- 1
Built for
What the system evolved to expect: the ground, light, food, movement, company.
- 2
Getting now
What modern life actually supplies, day to day.
- 3
The gap
What goes wrong in between, from flat feet and myopia to allergies and anxiety.
- 4
The protocol
What to do about it, starting with the one to three actions that matter most, each graded strong, probable or emerging.
What that looks like, in three chapters
Taken from the Mismatch Cards the book prints in each chapter, 15 in all.
Chapter 3 · The Body That Moves
The Body That Walks
The walking body: leg muscles and joints, heart and blood vessels, lymph, back and feet.
- Built for
- Hours on foot most days, rest in squats and on the ground, little salt and plenty of potassium, and use of a sore body while it heals.
- Getting now
- Nearly eight sedentary hours a day and about 5,100 steps for the average American, about 11 g of salt a day worldwide, and rest, scans and fear after injury.
- The gap
- Higher blood sugar within hours of sitting, blood pressure that climbs with age, knee arthritis in American skeletons that has doubled beyond what age and weight explain, and back pain that hardens into disability.
Chapter 6 · The Body That Eats
The Gut That Expects Dirt
The gut's microbes and the immune system's learned tolerance.
- Built for
- Tens of grams of fiber a day from many plants; microbes from siblings, animals, soil and food; early tastes of lifelong foods; fever and care while sick.
- Getting now
- About 17 g of fiber a day (the US adult average), small families and indoor lives, needless antibiotics, delayed allergenic foods until recently, and fear of the thermometer.
- The gap
- Fewer gut species, more allergy, autoimmune disease diagnosed in about one person in ten in the UK over two decades (mostly women), resistant bacteria and returning measles.
Chapter 8 · The Body That Reads Signals
Sleep
The circadian clock and the sleep it schedules, tuned by light, temperature and routine.
- Built for
- A bright day, a dark night that cools, and the same timing tomorrow; enough sleep, with room for naps.
- Getting now
- Dim days, lit evenings, a bedroom at one temperature with a phone in it, a schedule that lurches at weekends, afternoon caffeine, and for some, work through the night.
- The gap
- Sleep moves later and grows irregular; insomnia is common and often untreated; night workers live against their own clocks; apnea goes undiagnosed, especially in women after menopause.
Everything the book covers
Six parts, from the short version, through the body that moves, eats and reads its signals, to the social animal and the life course. Each line is a chapter, and the number is how many graded recommendations it carries.
Part 1. The Short Version
Part 2. The Body That Moves
Part 3. The Body That Eats
Part 4. The Body That Reads Signals
Part 5. The Social Animal
Plus a 30-day protocol with 7tracks for particular lives, a “where to start” map keyed to problems, a glossary, a further-reading list, and 488 notes citing 1,027 works. Behind it on this site sits a reference library of longer entries on every topic.

Page counts are the publisher's stated print length. Scope is judged from each book's full table of contents and published reviews; no book was read cover to cover for this table. Several of these books go deeper on their one subject than any single chapter here can, which is why four of them are on this book's reading list.
Why it is the better buy
Ten books' worth of ground
Walking, strength, food, the gut, light, sleep, heat and cold, green space, relationships, attention, stress, addiction and grief, women's health and aging, in one 343-page book from $12.99.
From why to what to do
Every part of you gets the evolutionary story and the practical fix: 53 recommendations, each in the chapter that explains it.
You know what to do first
Each recommendation is graded: 17 strong, 28 probable, 7 emerging. Every chapter opens its protocol with where to start.
A plan, not just a read
A 30-day protocol turns the book into a month of changes, one layer a week, with 7 tracks for particular lives and the cautions beside each step.
It shows its work
488 numbered notes citing 1,027 works, printed in the book, with every one also in the register on this site.
Dip in anywhere
Chapter 1 is the whole book in short. After it, every chapter stands alone, and the Prologue's map sends you straight to the chapter for what is bothering you.
Good company
4 of the ten are recommended inside this book, for readers who want to go deeper on one subject after seeing the whole map.

Common questions
- What makes Spiral Staircase different from other evolutionary health books?
- Scope and follow-through. Most books in the category take one slice of the body: food, breathing, exercise or metabolism. Spiral Staircase covers the whole body and the mind, from walking, strength and food to sleep, stress, relationships, women's bodies and aging, and for each sets out what it evolved to expect, what it gets now, what happens in the gap, and what to do about it. Its 53 recommendations are each graded by the strength of the evidence.
- Is there another book that covers the evolution of the whole body and turns it into advice?
- Not that we could find. Lieberman's The Story of the Human Body covers the evolutionary history broadly, but its prescriptions are mainly about society and policy. The practical books each cover one area. Spiral Staircase is, as far as we can find, the first to do both across the whole body and mind: the evolutionary story of each part of you, and graded, personal advice for giving it the conditions it evolved for.
- Is Spiral Staircase good value compared with other health books?
- The Kindle edition is $12.99 and the paperback $22.99, in the same range as the books compared here, for 343 pages, 16 chapters, 53 graded recommendations, 39 popular claims tested, and a 30-day protocol with 7 tracks for particular lives. Most of the books in the table are 280 to 500 pages on a single subject.
- Are the other books in the comparison bad books?
- No, and four of them are recommended in this book's own further-reading list. The comparison is about scope, not quality: several of them go deeper on their one subject than any single chapter here can.
