The 11 questions

  1. 1.

    Perlmutter argues that much of the dementia epidemic is preventable through diet. How credible do you find this claim, and what would it take to persuade you?

  2. 2.

    The book implicates whole grains — long considered a health food — as a driver of brain disease. How do you update your beliefs when expert consensus gets challenged this directly?

  3. 3.

    Have you noticed any connection between what you eat and how clearly you think or how stable your mood is? What was the context?

  4. 4.

    Perlmutter distinguishes between non-celiac gluten sensitivity and celiac disease. Does the former feel like a real clinical entity to you, or a trend diagnosis?

  5. 5.

    If a 60-gram daily carbohydrate limit would protect your brain in the long run, would you do it? What would be hardest to give up?

  6. 6.

    The blood sugar-cognition link is probably the best-supported part of the book. How much of the broader argument rides on that specific connection?

  7. 7.

    Perlmutter is a credentialed neurologist making heterodox dietary claims. Does that combination make you more or less skeptical than if the same argument came from an alternative health practitioner?

  8. 8.

    The book argues conventional medicine consistently misses dietary causes of neurological disease. Do you think that's a systemic failure, a function of evidence standards, or something else?

  9. 9.

    Perlmutter recommends a diet similar to what became keto and paleo trends. Does the overlap with fad diets affect how seriously you take his neurological argument?

  10. 10.

    What would you want to see in a clinical trial that would either confirm or refute Perlmutter's main thesis?

  11. 11.

    If dietary choices made in your thirties significantly shaped your brain health at seventy, how would that change the trade-offs you make today?

How to run the discussion

  • Pick six to eight, not all of them. An hour of real discussion covers fewer questions than anyone expects, and racing the list is what makes a book club feel like homework.
  • Open with what people noticed, not what they concluded. Asking for a verdict first hardens opinions before anyone has heard each other.
  • Let the disagreement run. The questions below that split a room are the ones worth the time; the ones everyone answers the same way can be skipped.
  • Ask the quiet person a specific question. A direct, narrow question is far easier to answer than an open invitation to contribute.

Themes worth steering toward
