Podbit · The Diary Of A CEO with Steven Bartlett
Poirier has never been a casual drinker — when he drinks, he drinks until the bottle is gone. He envies people who can stop at two. After the arrest and a conversation with his wife, he's made the definitive decision: alcohol is out of his life permanently, because it has never benefited him and he refuses to replicate his father's legacy.
Where this was said

Bartlett presses Poirier to describe depression in visceral terms, and Poirier delivers one of the most candid accounts in the episode: everything has its own gravity pulling toward the negative, like a cloud he can't escape. [1] — Dustin Poirier "Poirier describes depression as a state where everything has its own gravity pulling toward the negative — a cloud in your head you can't e…" 16:30 He traces the first recognisable onset to after a second fight loss to Justin Gaethje, when he began to notice deep emotional volatility. Therapy helped — he started unpacking childhood trauma he didn't know he was carrying, including the absence of his father, the domestic violence, and the burden of growing up with an addicted parent. But he made a critical mistake: when he started feeling better, he stopped practising what therapy taught him. The airport incident was partly the result of that lapse.
After 20 years of professional fighting, Poirier had no roadmap for who he was without it. The gym was therapy, competition was purpose, and the fight camp was structure — strip all three away and you're left with long, empty days and no dopamine equivalent. He always feared becoming 'that guy,' and then he did.
Poirier retired from UFC on July 30 in New Orleans after over two decades in the sport, having promised his wife he would retire by 35.
Poirier confirmed there is no formal support or roadmap provided by the UFC to help fighters navigate the psychological transition out of professional fighting.
Elite athletes pour everything into one thing — their entire nervous system calibrated to competition. When it ends, they're left chasing that same peak intensity in anything they can find, and it's often destructive. Poirier always said he'd never be 'that guy.' Then he was. He understands now why the pattern keeps repeating.
Spike your cortisol in the first 1–3 hours of your day — with sunlight, hydration, exercise, or caffeine — and you set up elevated mood, focus, and stress resilience for the rest of the day. Miss that spike and you get a flat cortisol curve: brain fog, poor learning, and bad sleep. The bookend is equally important: dim lights, no caffeine, and wind down the final hour.
Bottom-up impulses — just eat the cookie, keep scrolling — are driven by deep brain structures. Top-down prefrontal control is the thing that lets you wait, learn, and grow. Every small act of choosing the harder thing, from picking up trash to doing the workout you dread, greases that top-down circuit — and it transfers to everything else.
A Washington University in St. Louis study found that the attention-improvement effects of Ritalin are effectively equal to a great night's sleep. Stimulants also stunt growth and reduce sleep quality. The new direction is combining lower medication doses with genuinely better sleep — not replacing sleep with pharmacology.
Two big inhales through the nose, then a full exhale to empty — that's the physiological sigh. It fires a specific vagal pathway to slow your heart rate, offload CO2, and tip the autonomic nervous system toward calm instantly. Doing just 10 deliberate exhales throughout the day measurably elevates HRV by nighttime.
Presence isn't a state you fall into — it's something you actively produce by anchoring perception to the immediate environment. Ask 2–3 trivially specific questions about your surroundings (how many cans, what does it smell like) to pull your brain out of past/future mode. Then deliberately choose what to think or say next. That's it.
Acknowledge the thing, feel all of it, uncouple the emotion from the memory, then transmute the experience into something meaningful. Most people stall at step 2 — feeling the feelings — and never reach uncoupling. An entire generation is stuck there, confusing emotional processing for healing. Moving through all four is the actual path out.
Nicotine creates a uniquely alert-and-calm state ideal for learning — but only at low doses used occasionally. If you're using 3–6 mg pouches multiple times a day, you're not getting a cognitive enhancement, you're just rescuing yourself from withdrawal. For a genuine performance effect, use it once or twice per week at most.
Two injections of BPC-157 (100–200 mcg) eliminated shoulder pain Huberman couldn't shift for months. The peptide pinealon gave him 2.5–3 hours of REM sleep inside 6 hours — an effect that persisted into subsequent nights and scaled down to just once per week. Neither is in the book because the human data aren't there yet, but the animal evidence is strong.
Long, slow cardio builds capillary networks and mitochondrial richness; high-intensity intervals push VO2 max. You don't need huge volumes of either. Huberman's protocol: one 45–60 minute long slow session, one near-maximal effort HIIT session (Airdyne 20-on/10-off for 6–8 rounds), and one medium 30-minute effort per week. That's the complete cardio picture.
