Podbit · The Diary Of A CEO with Steven Bartlett
During Alzheimer's, the brain loses its ability to metabolize glucose — it enters a metabolic crisis. The brain responds by breaking down the myelin sheath to produce ketone bodies. A ketogenic or exogenous ketone strategy can supply the alternative fuel the brain is desperately seeking.

The episode's final chapter is a thought experiment with real practical weight. Bartlett asks: if Louisa Nicola herself were diagnosed with Alzheimer's tomorrow, what would she do? She responds without hesitation and with striking specificity [1] — Louisa Nicola "During Alzheimer's, the brain loses its ability to metabolize glucose — it enters a metabolic crisis. The brain responds by breaking down t…" 29:08 . First: aggressive, consistent exercise. Second: a ketogenic diet, or exogenous ketone supplementation. The reasoning is mechanistic — in Alzheimer's, the brain enters a metabolic crisis where it loses the ability to metabolize glucose effectively. Starved for fuel, it begins cannibalizing the myelin sheath. Astrocytes respond by producing ketone bodies as an emergency fuel source. A keto diet bypasses the broken glucose pathway and feeds the brain what it can still use. Third: aggressive lipid management and high omega-3 fatty acid intake, both of which support vascular and neuronal health. Finally: social engagement, hard conversations, going outside, and even throwing tennis balls against a wall — any activity that keeps the brain's plasticity alive for as long as possible. It's a protocol that circles back perfectly to everything discussed: the primacy of exercise, the importance of metabolic health, and the underrated power of keeping the brain active and connected.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
