Dr. Gurpreet Padda reframes dementia as a metabolic disease in new book

Dr. Gurpreet Padda’s new book, The Starved Brain, argues that dementia and age-related cognitive decline are often driven by overnutrition, nutrient deficits and metabolic dysfunction rather than fixed genetics. Released July 23, 2026, the book pairs a clinical framework with research citations and points readers to companion resources at thestarvedbrain.com and regen.md.

Why it matters: - The book argues that dementia is often treatable as a metabolic problem, which could change how clinicians think about prevention and early intervention. - Padda’s central claim is that many people are overfed on calories but undernourished in the nutrients the brain needs. - The book frames lifestyle, nutrient status and insulin-related dysfunction as potential levers for slowing cognitive decline.

What happened: - Dr. Gurpreet Padda, MD released The Starved Brain: How the Malnutrition of Excess Is Shrinking the Modern Mind — and How to Reverse It on July 23, 2026. - Regen.MD published the book and launched a companion resource at thestarvedbrain.com. - The book presents dementia and age-related cognitive decline as a predictable result of a brain “starved of what it needs and poisoned by what it gets instead.”

The details: - The book opens with two contrasting patient examples: a famine victim and a 58-year-old man in a Missouri waiting room who is not hungry but shows low vitamin B12, low omega-3 index, elevated homocysteine and declining cognitive screening scores over three years. - Padda describes that pattern as a “double burden of malnutrition,” and cites estimates that more than 80% of the population shows signs of metabolic dysfunction. - The book organizes cognitive decline around four measurable failures: fuel, structure, nutrients and inflammation. - In the fuel category, the book says the Alzheimer’s brain loses the ability to burn glucose years before symptoms appear, while ketone use is largely preserved. - In the structure category, the book says the brain contains more than a quarter of the body’s cholesterol and uses cholesterol and dietary fat to build myelin and synapses. - In the nutrients category, the book says a vitamin B12 level inside the lab “normal” range can still be associated with faster brain shrinkage. - In the inflammation category, the book links fructose, industrial seed oils, glycation and chronic gum disease to low-grade “metaflammation” tied to neurodegeneration. - The book says excess fructose can activate a biological starvation program that evolved to help animals survive famine. - Padda writes, “Excess doesn't merely coexist with starvation. Excess can switch on the starvation program itself.” - The book includes inline citations for substantive claims and grades the evidence as strong, preliminary, mixed or based on small studies. - The book cites ketogenic therapy as a standard of care for drug-resistant epilepsy and describes a meta-analysis of 10 randomized trials in 691 Alzheimer’s patients as showing modest cognitive benefit. - Padda writes, “A book that only tells you the good news is not a book you can trust with your brain.” - The book is positioned as a reference book, not a diet plan. - The book says major dietary change should be treated as a medical event and done with physician supervision, especially for people taking diabetes or blood-pressure medication. - The Starved Brain has ISBN 979-8-90600-156-6 and is the companion volume to a five-part video masterclass of the same name. - Additional information is available at thestarvedbrain.com and Regen.MD.

Between the lines: - The book is trying to move dementia discussions away from fatalism and toward modifiable risk factors. - Its evidence-grading approach suggests an effort to distinguish established science from emerging or contested ideas. - By emphasizing medical supervision, the book avoids presenting itself as a simple wellness or diet trend.

What's next: - Regen.MD says the book is part of a broader five-part video masterclass. - Readers and clinicians can follow the companion materials online for more context and supporting resources. - The book’s core test will be whether its metabolic framing gains traction in mainstream dementia prevention and care.
