Diary of a CEO
11 episodes — every digest for Diary of a CEO.

In this interview, Dustin Poirier opens up about his Father’s Day arrest at the Atlanta airport, explaining that he started drinking that day, got into a confrontation, and was charged with public intoxication. He reveals he has not watched the viral video and deleted all social media afterward to avoid public mockery. Poirier traces his struggles back to childhood trauma, noting he began drinking at age 12–13, was expelled from school, and grew up with an alcoholic father who is now homeless. He retired from the UFC on July 30th, leaving his gloves on the mat, and describes an ongoing identity crisis and emotional void, with some days feeling certain about retirement and others believing he can still beat top fighters. Poirier shares that a brain scan with contrast showed scarring, thinning in the back of his brain, and a separated septum that may impair communication between hemispheres. He also notices increased impulsivity, such as placing large bets or deciding to get drunk, but is unsure if this stems from head trauma or normal personality changes. He estimates only a 5% chance of returning to the UFC, a figure that continues to decline. On a positive note, Poirier discusses his Good Fight Foundation, which started by auctioning fight gear to support a fallen officer’s family and now runs an annual back-to-school drive providing 1,300 backpacks with supplies, operating with no paid staff to maximize impact. He also talks about his broadcasting contract with Paramount/CBS, expressing a fear of losing the desk role because fighting gave him and his family everything. Throughout the conversation, Poirier takes full responsibility for his actions, emphasizes he does not want to use mental health as an excuse, and shares that he is back in therapy, journaling, and working on maintaining stability.

This episode presents a comprehensive framework for understanding health, aging, and disease through the lens of mitochondrial function and energy dynamics. The central thesis is that most diseases, including Alzheimer's, diabetes, and mental illness, can be understood as states of energy resistance, where cells cannot efficiently process or utilize energy. The guest challenges the long-held amyloid hypothesis for Alzheimer's, noting that people can have significant plaque buildup without cognitive decline, and instead points to early hypermetabolism followed by hypometabolism in specific brain regions as a key mechanism. Gray hair is presented as a reversible symptom of energy allocation, with evidence that stress reduction, such as during a vacation, can restore color. The discussion emphasizes that mitochondria are not just energy producers but also signalers, acting as a distributed brain within cells. Practical advice includes eating according to mitochondrial needs rather than hunger cues, restricting eating windows, and challenging the necessity of breakfast for older adults. The episode also explores the link between purpose and mitochondrial efficiency, the role of focus in conserving energy, and the emerging field of metabolic psychiatry, where a ketogenic diet has shown life-changing results for some with treatment-resistant mental illness. The guest concludes with the philosophical and scientific statement that "we are energy," framing the body's biological processes as a coherent energy system.

Dr. Stephanie Estima argues that women should shift their fitness focus from weight loss to gaining muscle, bone density, and metabolic capacity. She identifies common archetypes, with "skinny fat Sophie" and "Exercist Emily" representing unhealthy patterns of under-eating and over-exercising, while "Dialed In Diana" is the ideal who fuels properly and uses exercise for self-care. Estima debunks several fitness myths: the fear of carbohydrates (which are needed for mood, sleep, and performance), the fear of lifting heavy (97% of women cannot hormonally bulk up), and the narrow post-workout anabolic window (muscle protein synthesis lasts 10–72 hours as long as total daily protein is sufficient). She recommends 3–4 strength training sessions per week and highlights sprinting protocols like the Norwegian 4x4 to improve VO2 max, which declines 10% per decade if not maintained. A study of postmenopausal women (average age 58) showed a 10% increase in VO2 max in 8 weeks, with mitochondrial efficiency improving 69%. The episode emphasizes that the scale is not a measure of worth, that calorie restriction is hard to sustain and spikes hunger hormones, and that increasing movement is often a healthier strategy. Resistance training is framed as building mental resilience, and the pursuit of thinness is linked to serious health consequences like osteoporosis.

In this episode, the speaker issues a stark warning about an impending economic crash, advising investors to sell all US stocks and technology holdings and instead allocate 60% to non-US equities, along with precious metals, real estate, and bonds. He argues that the US market's 20-year dominance is cyclical and not guaranteed, citing emerging markets' recent 65% gain versus the S&P's 25%. He dismisses cryptocurrency as "nonsense" that facilitates crime and predicts Bitcoin will go to zero. Real estate is also criticized as a poor investment due to an affordability crisis, with house prices rising from 3.4 times family income in 1994 to over 10 times today. AI is labeled the biggest investment bubble in history, comparable to railroads and the internet, with a collapse expected within days to years. The discussion then shifts to environmental toxins—phthalates, BPAs, PFAs, microplastics, and atrazine—and their verified links to declining fertility, sperm count, and reproductive capacity, citing Harvard and Mass General studies. The speaker shares a personal story of embryo freezing due to these concerns and argues for reforming capitalism to support raising children. Advice for average people includes bracing for tougher times, saving cash, upskilling in practical fields, and building strong social networks. The overall themes blend financial pessimism, environmental health warnings, and a call for long-term societal and personal resilience.

Dr. Rachel Rubin argues that a systemic failure in medical education and practice has left women's sexual health neglected, with profound consequences for their well-being and relationships. She highlights that simple, cheap interventions like vaginal estrogen cream—which can reduce pain, dryness, and UTIs while improving arousal—are not prescribed to over 75% of women who could benefit. A key educational gap is the omission of the clitoris from OBGYN training checklists as of 2026, despite most women requiring clitoral stimulation to orgasm. The episode explores how misunderstanding arousal styles (spontaneous vs. responsive) can damage relationships, with data showing men have roughly 70% spontaneous arousal versus 10-15% in women. Verified claims include that up to 27% of birth control users report decreased libido, no published studies exist on GLP-1 sexual side effects in women, and global consensus supports testosterone therapy for postmenopausal libido. Vaginal hormones are proven to prevent UTIs and are safe for all ages. The discussion also covers the prevalence of painful sex (up to 75% of women at some point, with 10-20% suffering chronic pain), the myth that sex should be spontaneous, and how body image issues block pleasure. Dr. Rubin calls for better doctor training, self-advocacy, and open communication, noting that even high-profile women like Melinda Gates, Oprah, and Halle Berry were misdiagnosed. The episode frames the current "sex recession" as a crisis of education and connection that can be reversed.

In this episode, Vice President JD Vance reflects on his political evolution, admitting he was wrong about Donald Trump and that his earlier characterization of Trump as a failed president was mistaken. He discusses the U.S.-Israel relationship, describing Israel as a junior partner while acknowledging shared strategic interests, particularly in weakening Iran’s conventional military power, though he cautions against turning Iran into a failed state. Vance expresses personal guilt over the impact of his public life on his son, who initially hated the attention but has since adjusted. He credits Charlie Kirk for helping him navigate that conversation. On economic issues, Vance argues that manufacturing job losses were driven by outsourcing and immigration, not automation, and predicts AI will boost productivity without causing mass unemployment, though he warns it could increase inequality and enable surveillance, likening AI-powered monitoring to a communist technology. He cites Pope Leo XIII’s encyclical on collective bargaining as a Christian alternative to Marxist class conflict. Vance also expresses lingering anger at George W. Bush over the Iraq War, discusses Iran’s internal fractures and willingness to negotiate, and confirms the Trump team had contingency plans for a Strait of Hormuz disruption. Verified claims include his past private message calling Trump “America’s Hitler,” his mother’s 11 years of sobriety, and his son’s evolving feelings about being the vice president’s child.

In this episode, Dr. Darren Candow discusses the science of creatine supplementation, emphasizing its benefits for metabolically stressed brains, muscle recovery, and functional ability in older adults. Verified claims include that creatine takes about a month to wash out of skeletal muscle, enhances recovery and training volume, increases lean mass by roughly 1.2 kg (with only half being skeletal muscle), reduces protein breakdown, and improves muscle performance across all ages when combined with weight training. A loading phase of four scoops daily saturates muscles faster but may cause gastrointestinal issues, while a steady 5 g per day is effective and well-tolerated. Creatine also improves functional tasks in older adults and, in one study, helped young females sleep an hour longer on training days. Dr. Candow notes that lighter weights taken to fatigue can build muscle mass similarly to heavy weights, though heavy weights are better for strength. He cautions against overhyping creatine, describing it as a multifunctional tool rather than a cure-all, and stresses that weight training is superior to cardio for overall health. Partially supported claims include creatine’s potential role in rehabilitation and its wide safety profile, though pregnant women and children require more research before firm recommendations can be made. The episode presents creatine as a safe, evidence-based supplement that works best as part of a broader health regimen centered on resistance training.

In this episode, Graham Hancock presents his case for a lost advanced civilization destroyed by a global cataclysm around 12,800 years ago, framing his arguments with a sense of personal urgency due to an upcoming surgery. He argues that anatomically modern humans have existed for at least 315,000 years, yet recognizable civilization only emerged about 6,000 years ago, suggesting a missing chapter in human history. Hancock points to the Younger Dryas impact hypothesis, Göbekli Tepe, and ancient maps like the Orontius Finaeus map as evidence of sophisticated knowledge and organized labor long before conventional timelines. He claims the Great Pyramid encodes advanced astronomical and mathematical knowledge, such as precession and Earth’s dimensions, which he believes was inherited from a lost civilization. Hancock also critiques mainstream archaeology for dismissing global flood myths and ancient traditions as local exaggerations, arguing they are memory banks of a real cataclysm. He advocates for open-minded investigation into phenomena like telepathy and telekinesis, and reflects on mortality, family, and the need to live a positive life. While some claims, such as the 315,000-year timeline for modern humans, are verified, many others—including the existence of a golden-age civilization 20,000 years ago and the Orion correlation theory—remain unverified or partially supported, with low to moderate confidence. The episode’s overarching theme is a challenge to modern scientific arrogance and a call to reconsider humanity’s ancient heritage.

This episode presents a wide-ranging debate on the structural decline of the middle class, driven by AI, automation, globalization, and tax policies that favor the wealthy. Verified claims show that top income shares have tripled since 1980 while bottom shares fell, and that the current "K-shaped" economy mirrors the early 1800s "Angles Pause," where technology enriched owners but harmed workers. Speakers agree that widespread ownership—of homes, businesses, and shares—is key to fixing the middle class, but disagree on the path: one side champions entrepreneurship and optionality, while the other argues that workers lack bargaining power and that markets must be harnessed through democracy and standards, not left to oligarchs. AI is seen as both a threat (replacing entry-level jobs and outsourced labor) and an opportunity (augmenting small businesses), but the transition period is expected to be painful. The debate contrasts trickle-down versus middle-out economics, with one speaker arguing that foundational beliefs about how prosperity is created determine policy outcomes. Socialism is rejected as merely redistributive, while markets are praised as evolutionary systems that must be governed for broad benefit. The episode concludes that explaining the rules of the digital economy and teaching entrepreneurship can restore hope, but systemic change requires confronting corporate tax avoidance and rethinking ownership.

In this episode, mathematician and Christian apologist John Lennox argues that faith in God is grounded in evidence and reason, not blind belief, while warning against treating artificial intelligence as a godlike entity. He emphasizes that consciousness—including appreciation of life, beauty, and God—is a "hard problem" that AI cannot replicate, as machines lack qualia, senses, and genuine understanding. Lennox contrasts Christianity with other belief systems, noting that while devout Muslims and Hindus may experience similar psychological peace, he questions whether subjective feeling proves truth. He asserts that Christianity is unique in offering grace and forgiveness rather than merit-based salvation, and that rejecting this grace is a form of arrogance. The discussion also touches on transhumanism, the historical trial of Jesus for political terrorism, and C.S. Lewis's observation that the golden rule appears across many religions, suggesting a moral hardwiring. Lennox draws on Iain McGilchrist's work to critique the West's overemphasis on left-brain rationalism at the expense of context and beauty. Ultimately, he presents faith as a reasoned trust based on personal evidence, analogous to trusting a spouse or science, and argues that reductionist materialism leads to meaninglessness, pointing instead to a larger reality beyond the physical.

In this episode, Mo Gawdat, a former Google officer, presents a mixed outlook on technology and society. He argues that AI itself is not the enemy; the real danger lies in how humans direct it, a claim verified as accurate. Gawdat reflects on his time at Google, noting that while the company built tools with altruistic intentions, the world often misuses them for capitalist ends—a verified observation. He reaffirms his prediction that artificial general intelligence (AGI) will arrive by 2027, though this remains unverified. The primary challenge, he says, is economic: job loss among knowledge workers could trigger a downward spiral, a claim needing further research. Gawdat advocates for nations to invest in AI sovereignty rather than relying on imported technology, and suggests that open-source AI can handle 80% of tasks, enabling local innovation. He envisions a future where entrepreneurship replaces traditional employment, and universal basic income (UBI) could revive barter and small community economies. However, these predictions are speculative. Ultimately, Gawdat expresses optimism about the long-term future but warns of imminent near-term disruptions, emphasizing that human connection and resonance will become the ultimate skills if economies remain stable.
