The Longevity Diet (Hardcover)
Valter Longo on fasting-mimicking, pescatarian patterns, and periodic resets
USC longevity researcher Valter Longo’s book on a mostly plant, pescatarian-leaning pattern plus periodic fasting-mimicking diet (FMD) cycles. Less biohacker-stack, more Mediterranean-plus-reset. ProLon is the commercial FMD; the book explains the research story and everyday plate.
Typical price: $18 – $28 USD
How It Works
Longo’s lab links periodic fasting and FMD to reduced IGF-1, autophagy signals, and metabolic reset in animals and some human trials. Everyday diet is the other half. ProLon is a food kit, not in this product listing — the book is the primer.
Everyday Longevity Plate
Vegetables, legumes, nuts, olive oil, some fish — closer to Greger/Li than to keto.
Periodic Fasting-Mimicking
Multi-day low-calorie, low-protein cycles studied for metabolic markers. Clinic or kit, not a DIY water fast.
Protein by Age
Longo is conservative on protein in midlife and more liberal later to protect muscle — compare with our protein-longevity guide.
What You'll Experience
Reading
1 weekReaders usually tighten the daily plate before booking an FMD cycle.
Optional Cycle
5 days, a few times a yearFMD is fatiguing for some. Medical clearance if you have metabolic disease or take meds.
Benefits
Research-Lab Voice
Moderate EvidenceMore fasting-mimicking science than most popular diet books.
Compatible With EVOO / Plants
Moderate EvidenceStacks cleanly with Li, Greger, and olive-oil habits.
Risks & Considerations
DIY Multi-Day Fasts
high riskDo not invent a 5-day water fast from a book if you have medical conditions.
Low Protein in Older Adults
medium riskSarcopenia risk if you under-eat protein after 65 — see the protein guide.
Community Reviews
Synthesized consensus from Reddit, forums, and expert sources.
Clear everyday diet; FMD chapters drive kit purchases. Protein-by-age advice is the usual debate with Attia readers.
