EP 98: What Is Your Digital Diet Doing to Your Brain? with Jocelyn Brewer
We talk a lot about what we eat, how we move and how we sleep. We talk far less about what we consume digitally. In this episode I sit down with Jocelyn Brewer, Sydney-based psychologist and founder of Digital Nutrition, to explore what our digital diet is really doing to our brains. I had just come back from hiking the Camino with almost no access to technology, so this conversation was very much on my mind. Jocelyn has spent over a decade translating complex research into practical, human-friendly language. We get into why screen time is far more nuanced than “good” or “bad”, what technology is doing to loneliness and friendship, how short form content trains our attention, and why we need to think carefully about outsourcing our thinking to AI. We also cover simple, realistic ways to design a digital diet that works for your life, without going cold turkey. KEY TOPICS What digital nutrition is and why the “virtual vitamins” analogy keeps getting stronger Why screen time is more complicated than the hours on your phone What technology is doing to loneliness, friendship and our tolerance for human discomfort Why short form content trains our brains for short bursts and how to rebuild attention How AI is changing the way we think, work and relate to each other What leaders can do to reduce digital overwhelm in their teams Why digital detoxes often fail and what a healthy day to day digital diet looks like The one change Jocelyn would encourage everyone to make tomorrow ABOUT JOCELYN Jocelyn Brewer is a Gadigal Sydney-based psychologist and the founder of Digital Nutrition.
