Why Alzheimer’s May Be a Metabolic Disease

from The Metabolic Classroom with Dr. Ben Bikman

📢 Ask Dr. Bikman’s Digital Mind (multilingual):https://benbikman.com/ben-bikmans-digital-ai-mind📢 Dr. Bikman’s Community & Coaching Site: https://insuliniq.comTopic:Alzheimer’s disease has traditionally been explained by the buildup of amyloid plaques in the brain, but growing evidence suggests this theory does not fully account for the disease or lead to effective treatments. A metabolic perspective proposes that Alzheimer’s may instead be driven by brain insulin resistance, which disrupts neuronal energy metabolism—while the brain’s ability to use ketones as an alternative fuel remains intact, offering potential strategies for prevention and support.Summary:For decades, Alzheimer’s disease has largely been understood through the lens of the amyloid plaque hypothesis, which proposes that sticky protein deposits in the brain trigger neurodegeneration and cognitive decline. In this Metabolic Classroom lecture, Ben explains why that theory is increasingly being questioned. He reviews the historical origins of the plaque hypothesis and the repeated failure of drugs designed to remove amyloid plaques to meaningfully improve patient outcomes. The controversy surrounding manipulated data in influential Alzheimer’s research further highlights the need for a new framework to better explain the disease.Ben then presents a compelling alternative: Alzheimer’s disease as a metabolic disorder driven by brain insulin resistance. Drawing from mechanistic studies, epidemiological data, and genetic insights, he explains how impaired insulin signaling in the brain can disrupt neuronal energy metabolism, increase tau tangles, impair amyloid clearance, and ultimately contribute to neurodegeneration. This concept has led some researchers to refer to Alzheimer’s as “Type 3 diabetes.”The lecture also explores a hopeful implication of this metabolic framework. While glucose metabolism is impaired in Alzheimer’s brains, research shows that the brain’s ability to use ketones remains intact. This suggests that strategies that improve insulin sensitivity or increase ketone availability—such as carbohydrate restriction, fasting, exercise, or exogenous ketones—may offer promising avenues for prevention or metabolic support.References:For complete show notes and references, we invite you to become an Insider subscriber.
