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

Dr. Gurpreet Padda’s new book, released July 23, 2026 through Regen.MD, argues that dementia and age-related cognitive decline often stem from overnutrition, nutrient deficiency and metabolic dysfunction rather than fixed genetics. The book pairs that thesis with a clinical framework, cites research throughout, and points readers to a companion site and video masterclass.

Why it matters: - The Starved Brain argues that cognitive decline may be more preventable and modifiable than many patients assume. - The book frames dementia as a metabolic disorder tied to overnutrition, nutrient deficits, inflammation and insulin dysfunction. - The message could affect how patients think about brain health, diet and when to seek medical supervision for major dietary changes.

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, along with its companion resource at more information. - The book is described as a reference work, not a diet plan. - The book is the companion volume to a five-part video masterclass of the same name. - Additional information is available at the companion site and Regen.MD. - The ISBN is 979-8-90600-156-6.

The details: - The central thesis says most dementia and age-related cognitive decline are not a fixed genetic verdict, but a modifiable outcome of a brain starved of what it needs and overloaded with what it does not. - Dr. Padda says, “Genes load the gun. But lifestyle, nutrient deficiency, chronic hyperinsulinemia, and metabolic inflammation are what pull the trigger.” - The book opens with a famine victim and a 58-year-old Missouri man who has never gone hungry but shows low-normal vitamin B12, a low omega-3 index, elevated homocysteine and declining cognitive screening scores over three years. - The book uses that contrast to argue for 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. - Under fuel, the brain’s ability to burn glucose falls years before Alzheimer’s symptoms appear, while ketone use is largely preserved, a pattern researchers have called “type 3 diabetes.” - Under structure, the book says the brain contains more than a quarter of the body’s cholesterol and makes its own cholesterol, which helps form myelin and synapses. - Under nutrients, the book says a vitamin B12 result in the “normal” lab range can still be linked with faster brain shrinkage because reference ranges reflect averages, not optimal levels. - Under inflammation, the book points to fructose, industrial seed oils, glycation and chronic gum disease as drivers of low-grade “metaflammation” linked to neurodegeneration. - The book says excess fructose can trigger an ancient biological starvation program that lowers cellular energy and increases foraging behavior. - Dr. Padda writes, “Excess doesn't merely coexist with starvation. Excess can switch on the starvation program itself.” - The book says every substantive claim carries an inline citation and grades its own evidence as strong, preliminary, mixed or based on small studies. - The book also notes places where data contradict claims made by some advocates of similar arguments. - Ketogenic therapy is presented as a century-old standard of care for drug-resistant epilepsy. - A meta-analysis of 10 randomized trials in 691 Alzheimer’s patients is described as showing real but modest cognitive benefit. - Dr. Padda writes, “A book that only tells you the good news is not a book you can trust with your brain.” - The book emphasizes that significant dietary change is a medical event that should happen under physician supervision, especially for people taking diabetes or blood pressure medication.

Between the lines: - The book tries to split the difference between a popular wellness narrative and strict medical caution. - Its evidence-grading approach is meant to make the argument more credible than books that overstate certainty. - The “malnutrition of excess” framing gives a simple label to a growing cluster of metabolic risk factors that may shape brain aging.

What's next: - The book’s companion video masterclass is expected to extend the same framework in a five-part format. - Regen.MD and thestarvedbrain.com are the main places readers can find additional material. - The release may push more attention toward metabolic testing and medically supervised nutrition changes as part of cognitive health discussions.
