The Diary Of A CEO
Every question is a chapter.
166 episodes from 10 Feb 2025 – 14 Sep 2026 · 334 hours.
What it is
Steven Bartlett interviews scientists, doctors, founders and performers about how bodies and businesses work — sleep, hormones, cancer research, cold exposure, dopamine, what a career costs. The thumbnails promise more than the conversation does, but the conversations themselves are long and specific, and the guests are usually the person who ran the study.
Who's on it
Hosted by Steven Bartlett. Guests are predominantly researchers and clinicians, with entrepreneurs and public figures alongside them.
What it's good for asking
- What have experts said about vitamin D dosage?
- What does the show say about VO2 max and lifespan?
- Which guests disagreed about fasting?
Questions are answered only from these episodes' transcripts, and every answer cites the episodes and timestamps it used — so you can go and check it. Things a search box can't do: "what did they say they were worried about?", "has their position changed?", "which episode was that mentioned in?"
