Sleep. Eat. Exercise.

Hype examined

Eighty-three pages on the few things that change health outcomes, and nothing else. Every claim is traced to a primary source and carries a grade for how good that source is.

Where this is right now. The book is a manuscript out for review with clinicians and researchers. It is not on sale yet. When it is, it will be printed and nothing else: no ebook, no PDF. Leave your email below and I will tell you when you can order one. If you are a reviewer, start here.
What it is

A short list, not a long book

You already know the basics. Sleep more, eat better, exercise more. What you do not have is a way to tell which parts of the noise are worth anything: the cold plunges, the peptides, the fasting windows, the shelf of supplements. This book reads the research, keeps the short list of things that change outcomes, and cuts whatever did not survive the evidence.

Four promises it keeps:

No miracle supplement
No glucose panic
No anti-aging pill
No 30-day fix
The method

Why you could believe any of it

Because the method is the credential. Almost every claim in the book is traced to a study, and every study carries a grade for how good it is. Where the evidence is thin, the book says so. Where a number is a working rule rather than a trial result, the book says that too.

GradeWhat earns it
StrongMeta-analysis or systematic review of randomized trials, large enough to settle the direction.
EstablishedAt least one well-conducted randomized trial, or evidence settled enough that the direction is not in dispute.
ModerateProspective cohorts, or more than one small trial. Most useful lifestyle evidence sits here.
EmergingCross-sectional or mechanistic work, animal studies, or one small trial on its own.
GuidelineA clinical body reviewed the evidence and made a recommendation, and the book says which body.
BackgroundReading that informs the argument without being a study, so it carries no grade.
What is in it

Three pillars, one system

The book treats sleep, food and training as one loop rather than three separate lists, because that is how the evidence behaves. Twelve pathways connect them. Five are established and drawn solid; the other seven are associations and drawn dashed.

Sleep · the base

A fixed wake time, morning light, caffeine and alcohol timing, and what each stage of the night does.

Eat · the fuel

Protein and plants, the six nutrients that matter, fiber, and the gut as something you feed rather than test.

Exercise · the engine

Strength, an easy aerobic base, a little hard work, balance, and where recovery happens.

Then what sits on top: which numbers are worth tracking, which extras earn their place, whether any of it lasts, and thirteen situations for when life lands on you.

The conflict

Where I sit, and where that might show

I work in wellness, so I sell into the same space this book covers. Read all of it knowing that.

I grade supplement categories on the evidence like everything else, and I grade most of them down, including the ones I work in. Support comes last in the book, is graded hardest, and sits behind a screen designed to talk you out of most of it. Wherever a free basic does the job, the book says to do that instead.

The place my interest is most likely to show is sleep. It goes first and gets as much room as any pillar, partly because of the evidence and partly because it is what I know best.

Paper only

There will be no ebook

This book will be printed and sold as a printed object. No ebook, no PDF, no app.

That follows from what it argues. The whole book says to fix the foundations before buying anything clever, and it would sit badly to deliver that as one more tab you never go back to. Two of the pages are designed to be torn out and kept, which only works on paper. And a book you can read in an afternoon is a book worth sitting down with.
