Executive summary

Dr. Michael Greger is a physician, New York Times bestselling author, founder of NutritionFacts.org, and a high-profile advocate for whole‑food, plant‑based nutrition; his site and book releases show heavy activity in late 2025 including a 10th‑anniversary edition of How Not to Die due Dec. 9, 2025 and frequent webinars and speaking dates [1] [2]. He runs an active public program—podcast, webinars, books, documentaries and live events—while donating proceeds from books and talks to charity, which shapes how his work is distributed and promoted [2] [3].

1. Who is Dr. Greger and what does he promote?

Michael Greger, M.D., FACLM, is described across his official sites and press materials as a physician, author, and internationally recognized speaker who promotes evidence‑based nutrition with a strong emphasis on whole‑food, plant‑based diets; he is the founder of NutritionFacts.org and the author of How Not to Die and its spin‑off titles [2] [3].

2. Recent and upcoming publications set the public agenda

Press releases and retail listings show a flurry of new or revised works in late 2025: a revised 10th‑anniversary edition of How Not to Die scheduled for Dec. 9, 2025 (available for preorder) and other titles including a book on ultra‑processed foods and a How Not to Age cookbook discussed in 2025 materials [1] [4] [5]. These release dates and preorders are central to his public visibility and to marketing campaigns highlighted on his platforms [1] [4].

3. The NutritionFacts platform: reach, content and formats

NutritionFacts.org publishes videos, blog posts, podcasts, and webinars summarizing nutrition research; the site lists recent posts and dates in late November–early December 2025 and advertises live webinars and recordings that expand Greger’s reach beyond books into multimedia education [2] [6]. The platform emphasizes translating peer‑reviewed evidence into practical advice, a framing repeated in promotional blurbs [2].

4. Live events, charity and commercial strategy

Dr. Greger appears frequently at conferences and public events (e.g., speaking at the 2025 International Conference on Nutrition in Medicine and other summits), and his team notes that proceeds from books, DVDs and speaking go to charity—an explicit institutional choice that shapes public perception and distribution channels [5] [7] [3]. Ticketing marketplaces and event listings portray him as a top public speaker in 2025, underscoring a commercialized public presence alongside charitable claims [8] [7].

5. How he frames the science—and controversies that can follow

Greger’s messaging repeatedly frames chronic disease as largely preventable through diet, citing broad claims—e.g., that the 15 leading causes of death claim 1.6 million Americans annually and that diet and lifestyle can prevent many such deaths—language that appears in book copy and promotions [1] [9]. Available sources do not mention specific academic disputes or critiques of Greger’s interpretations, though the promotional tone and choice of emphatic assertions suggest a public‑health advocacy stance rather than a neutral literature review [1] [9].

6. New projects: documentary and ultra‑processed foods book

The Greenbaum Foundation‑commissioned documentary about Greger’s life and work has an advanced screening referenced on NutritionFacts.org tied to the 10th anniversary of How Not to Die, indicating institutional efforts to curate his public image [10]. Separately, a forthcoming book on ultra‑processed foods (released Jan. 21, 2026 per trade press) narrows his focus to a current hot topic in nutrition research—the book promises to examine 16 proposed mechanisms linking ultra‑processed foods to health risks [4].

7. What’s missing from the current reporting

Available sources do not mention independent evaluations of the accuracy of Greger’s summaries against the wider scientific literature, detailed critiques from major nutrition authorities, or independent sales figures beyond bestseller labels; they do not provide peer‑reviewed assessments of any claims in his books [1] [2] [4]. For readers seeking balance, those independent appraisals are not found in the current reporting.

8. Practical takeaways for readers and consumers

Dr. Greger’s work is packaged across books, webinars, podcasts and live events to influence public eating behavior; those packages are backed by a charitable‑proceeds narrative and active promotion through preorders and screenings [1] [7] [10]. Readers should treat his summaries as an advocacy‑driven distillation of research and seek independent, peer‑reviewed sources and clinical guidance for individual medical decisions—current reporting does not supply third‑party critiques to fully corroborate every claim [2] [4].

Limitations: this analysis uses only the supplied search results and cites them directly; independent academic reviews, critiques, and sales data were not included in the provided material and so are not addressed here [1] [2] [4].
