Podbit · The Diary Of A CEO with Steven Bartlett
Dr. Estima competed at 11% body fat — at the very floor of essential fat for women — following every rule: restrict calories, do cardio, earn recovery. She lost her period for months, gained all the weight back, and hated herself throughout. The experience became the foundation of everything she now teaches.

The conversation shifts personal as Dr. Estima describes the arc that shaped her philosophy. She studied neuroscience and psychology at the University of Toronto, trained as a personal trainer, then spent 20 years in chiropractic practice seeing tens of thousands of patients. But the moment that crystallised everything was competing in a figure competition at 11% body fat — right at the bottom of what's biologically essential for women (10–13%). She had followed every rule: restrict calories, do lots of cardio, earn your recovery. She lost her period for 2–3 months before stepping on stage. Ironically, strangers were showering her with compliments as she starved — a confusing and ultimately damaging experience she now sees as the ur-example of how women hitch their worth to external validation.

Dr. Estima competed in a figure competition at 11% body fat — right at the bottom of essential fat range — and lost her period for 2–3 months before stepping on stage.
Women's essential body fat is approximately 10–13%; dropping below this threshold causes serious hormonal disruption, including loss of menstrual cycle.
A healthy body fat percentage for most women falls between 18 and 25%, well above the dangerously low levels often pursued through restrictive dieting.
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.
