E385: Peter Attia

World’s #1 Longevity Expert: What Fitness & Diet Should Look Like After 30 (E385)

We’re delighted to welcome back Dr Peter Attia to High Performance, one of the leading voices in modern medicine and longevity. Known for his rigorous, evidence-based approach to health, Peter has built his work around a simple but demanding question: how do we live longer and better?

In this episode, Peter dives deep into what truly drives long-term health. He explains why exercise remains non-negotiable, how strength and cardiovascular fitness underpin independence as we age, and why the new wave of metabolic drugs are changing the conversation around heart health, cognition, and disease, without replacing the need for movement and training.

Peter also shares how he thinks about aging in practical terms, introducing the idea of “backcasting” from later life to guide the choices we make today. He breaks down which supplements actually matter, why he’s sceptical of health fads, and how balance, adaptability, and emotional wellbeing play a bigger role in longevity than most people realise.

Grounded, thoughtful, and highly practical, this episode offers a clear framework for protecting your body, your mind, and your quality of life, now and in the decades to come.
