Dr. Gurpreet Padda’s new book links dementia to overnutrition

Dr. Gurpreet Padda has released The Starved Brain, a new book that argues cognitive decline is often driven by metabolic dysfunction, not just age or genetics. The book, out July 23, 2026, frames dementia as a modifiable condition tied to excess calories, nutrient deficits and inflammation.

Why it matters: - The Starved Brain argues that dementia and age-related cognitive decline are often driven by metabolic dysfunction that may be modifiable. - The book’s core claim is that many people are overfed on calories but undernourished in the materials the brain needs to function. - The framing could shift how patients and clinicians think about prevention, screening and treatment.

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 is presented as a clinical framework for understanding cognitive decline as a metabolic disease of overnutrition.

The details: - The book argues that dementia is not a fixed genetic outcome for most people. - Dr. Padda writes that the brain can be “starved of what it needs and poisoned by what it gets instead.” - The opening chapters compare a famine victim with a 58-year-old Missouri patient who has never gone hungry but shows low-normal vitamin B12, a low omega-3 index, elevated homocysteine and declining cognitive screening over three years. - The book calls that pattern a “double burden of malnutrition,” a term the World Health Organization has used for years. - The book cites estimates that more than 80% of the population shows signs of metabolic dysfunction. - The book organizes cognitive decline into four measurable failures: fuel, structure, nutrients and inflammation. - In the fuel category, the book says the brain’s ability to burn glucose falls years before Alzheimer’s symptoms appear, while ketone use is largely preserved. - The book describes that pattern as “type 3 diabetes.” - In the structure category, the book says the brain contains more than a quarter of the body’s cholesterol and makes its own cholesterol. - The book says cholesterol and dietary fat are structural materials for myelin and synapses. - In the nutrients category, the book says a vitamin B12 result inside the lab “normal” range can still be linked to faster brain shrinkage. - In the inflammation category, the book points to fructose, industrial seed oils, glycation and chronic gum disease as drivers of low-grade “metaflammation.” - The book says research on fructose shows it can activate an ancient starvation-response program, lower cellular energy and drive foraging behavior. - The book states, “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 century-old standard of care for drug-resistant epilepsy. - The book says a meta-analysis of 10 randomized trials in 691 Alzheimer’s patients showed modest cognitive benefit from ketogenic therapy. - Dr. Padda writes, “A book that only tells you the good news is not a book you can trust with your brain.” - The Starved Brain is described as a reference book, not a diet plan. - The book says major dietary change should be supervised by a physician, especially for people taking diabetes or blood pressure medication. - The Starved Brain is the companion volume to a five-part video masterclass of the same name. - The book’s ISBN is 979-8-90600-156-6. - Additional information is available at thestarvedbrain.com and regen.md. - Regen.MD also shared a YouTube link: Regen.MD on YouTube.

Between the lines: - The book tries to position itself between popular anti-aging claims and clinical skepticism. - Its emphasis on evidence grading suggests an effort to build credibility in a crowded wellness category. - The medical-supervision warning signals that the book is not promoting unsupervised diet changes.

What’s next: - Regen.MD says the book is paired with a five-part masterclass, which could extend its reach beyond print. - The companion website appears to be the main hub for follow-up material and additional information. - The book’s clinical framing may invite more debate about how much dementia prevention is tied to metabolism, nutrition and inflammation.

The bottom line: - The Starved Brain makes a clear case that cognitive decline may be more preventable, and more metabolically driven, than many readers assume.
