Podbit · The Diary Of A CEO with Steven Bartlett
Extended fasting windows don't just restrict calories — they send a famine signal to a woman's ovaries, which contain roughly 100,000 mitochondria per egg and are constantly scanning the environment for safety. The result: suppressed ovulation, disrupted cycles, and cascading hormonal damage.

Dr. Estima's third myth targets long fasting windows — 20, 24, 36, 72 hours and beyond. The female body is uniquely sensitive to energy availability because it has to decide each cycle whether conditions are safe for pregnancy. With 100,000 mitochondria per egg cell, ovaries are extraordinary energy scanners. Prolonged fasting signals famine, shutting down ovulation. Rather than extended fasts, Dr. Estima recommends a natural overnight fast: stop eating 2–3 hours before bed, sleep 8–9 hours, eat breakfast — totalling 10–11 hours of fasting. Pushing the eating window further compresses the space available to consume sufficient protein, calories, and macros.

Women have 10 to 20 times less testosterone than men, which is why even identical training programmes produce far less muscle mass in women.
Fasting windows of 20, 24, 36, or 72+ hours can signal famine conditions to the female body, suppressing ovulation and disrupting hormonal cycles.
Each human egg cell contains approximately 100,000 mitochondria, making female ovaries acutely sensitive to energy availability and fasting signals.
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.
