Podbit · On Purpose with Jay Shetty
Every human culture has practised fasting as either a healing or religious ritual for millennia. Science is now revealing why: fasting triggers profound metabolic and cellular renewal processes. The ketogenic diet works by tricking the body into a fasting state without actual starvation.

Nutrition, Palmer says, is where the 'give me three recommendations for everyone' framing breaks down irretrievably. Different gut microbiota, genetics, epigenetics, food sensitivities, and preferences mean that what thrives one person destroys another — someone with celiac disease cannot follow whole-grain guidance; someone with severe nut allergies can't follow the nut-consumption advice. [1] — Dr. Chris Palmer "Eat real whole foods that your great-grandparents may have seen on their table, on a plate somewhere, somehow. And you can process them you…" 41:40 Rather than paralysing listeners, Palmer offers a practical framework: think about nutrition in terms of getting adequate nutrients, achieving or maintaining a healthy weight, identifying and eliminating food sensitivities, and — for more compromised people — using dietary interventions therapeutically. The one near-universal principle he lands on: eat real whole foods that your great-grandparents might have seen on their table. The enemy isn't cooking or spices — it's the plastic-wrapped product with 15 unpronouceable ingredients.
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.
