Ultra-Processed People (Hardcover)
Van Tulleken on food that isn’t food — the factory, not your willpower
Physician Chris van Tulleken’s 2023 US hardcover: most calories now come from ultra-processed food, defined as industrial formulations you would not cook at home. He ate an 80% UPF month under lab watch. Pair with Lustig, Guyenet, and Fiber Fueled. Hardcover ASIN 1324036729 is in the buy box.
Typical price: $18 – $32 USD
How It Works
UPF as hyper-palatable, cheap, and engineered for overeating. Strongest as a shopping rule. Weaker as a clinical protocol — diabetes drugs stay with a clinician.
Not Food
If it is wrapped in plastic and has an ingredient you would not keep in a kitchen, treat it as a product, not a meal.
The Month
The self-experiment is the hook. The point is the food environment, not a 30-day cleanse you post.
Not a Diet Book
No macros. Drop the factory food, keep walking and protein. See Metabolical for the liver/gut rule.
What You'll Experience
Reading
A weekMost people clear the pantry of bars and sodas, not start a peptide.
After
MonthsIf the only change is a new ‘clean’ protein bar, you bought another UPF.
Benefits
Pairs With Lustig
Moderate EvidenceMetabolical is liver and gut; this book is the ingredient list.
Anti-Shame
Moderate EvidenceUseful if you have been told obesity is a character flaw.
Risks & Considerations
Not a Drug-Stop Card
high riskDo not quit metformin or a GLP-1 because a hardcover explained cereal.
Orthorexia Trap
medium riskA homemade meal beats a perfect label. Do not turn ‘no additives’ into a fear of fruit.
Community Reviews
Synthesized consensus from Reddit, forums, and expert sources.
Praised as the clearest UPF explainer. Some wanted more recipes. The definition chapters are the part people cite.
