Podbit · The Diary Of A CEO with Steven Bartlett
A Mayo Clinic study showed people on a fat-based diet (fish, avocado, nuts) had 42% less Alzheimer's risk, while those on a standard American carbohydrate diet had 400% more risk. Sugar and foods that rapidly convert to sugar are the core culprit.

The diet-Alzheimer's connection is where the BRIGHT MINDS framework becomes most actionable. A Mayo Clinic study that compared dietary patterns found a dramatic gradient: people eating primarily healthy fats (fish, avocado, nuts, seeds) had 42% less Alzheimer's risk; those on a protein-dominant diet had 21% less risk; and those on the standard American diet — bread, pasta, potatoes, rice, fruit juice, sugar — had a staggering 400% increased risk. [1] — Dr. Daniel Amen "A Mayo Clinic study showed people on a fat-based diet (fish, avocado, nuts) had 42% less Alzheimer's risk, while those on a standard Americ…" 1:09:15 The mechanism is the insulin-diabetes type 3 hypothesis: chronic high blood sugar makes blood vessels brittle and prone to rupture, slowing healing and vastly increasing stroke risk. And having a stroke increases Alzheimer's risk tenfold. Fat cells themselves produce adipokines — inflammatory molecules that further damage the brain. Amen cites his 33,000-person study confirming that as body weight rises, brain size and function fall. He is not fatphaming, he insists — he is reporting science. For those designing a brain-protective diet, he favours a paleo approach with healthy fats, quality protein, and an abundance of plants over pure keto, which he worries may be insufficiently plant-diverse for a healthy gut microbiome.
A Mayo Clinic study found that people who primarily ate a fat-based diet (fish, healthy oils, avocados, nuts) had a 42% lower risk of developing Alzheimer's disease.
A Mayo Clinic study found people eating a primarily simple carbohydrate diet (bread, pasta, sugar) had a 400% increased risk of getting Alzheimer's disease versus those on a fat-based diet.
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.
