Does Obesity Shrink Your Brain? The Neurodegeneration Debate | Confounding vs. Causal Mechanisms

from The Muscle Building and Fat Loss Podcast · host Circle Of Insight Productions

Is obesity truly reprogramming your brain and accelerating dementia, or is the link mostly genetics and family environment? We dive into Eric Topol’s March 2026 Nature Metabolism perspective on brain-wide damage mechanisms versus the 2023 sibling study showing associations vanish within families—plus the key limitations of both studies. Balanced, evidence-based take on one of health’s hottest controversies. (Ideal for longevity, metabolic health, and science podcast fans.)
