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.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
