The Method - Health in the Real World

We all know that eating well matters; but what does that actually mean for you, specifically? Low-fat, low-carb, mediterranean, keto, intermittent fasting… What if the reason no single diet works for everyone is because no single diet should?

In this episode, Greg and Charlie sit down with Dr. Lucia Aronica, an epigenetics and nutrigenomics scientist at Stanford University School of Medicine, who has contributed to the DIETFITS study, one of the best-known trials in the field of personalised nutrition. 

Lucia will break down what factors shape personalisation, and what the research really shows. We discuss the findings of the DIETFITS study, explain how individual responses vary, and break down what variables really matter for a healthy diet. We then zoom out to ask the bigger question: is there actually compelling evidence that a personalised nutrition plan beats a well-designed, healthy, generic one?

From there, we move into our practice segment, where Lucia shares what this all means day-to-day. We cover:
  • The healthy eating principles that apply to all of us, whatever our goals (21:41)
  • Why testing insulin is crucial (25:06)
  • Why pleasure is the key to adopt long-lasting healthy eating habits (29:21)
Finally, in the experience section, we pick up on your questions. From the future of DNA-based nutrition to the truth about keto and your microbiome, meal timing, insulin spikes, and whether that daily tablespoon of olive oil is as good as people say, Lucia gives her take on some of the most common (and most debated) questions in nutrition today.

Personalised nutrition is a genuinely exciting scientific territory, but at times, it can be overhyped. This episode helps you figure out what the evidence actually supports, and what practical steps you can take right now.

What is The Method - Health in the Real World?

There’s no shortage of health advice out there, but how much of it actually works? Cold plunges, glucose monitors, protein timing, strength training, avoiding microplastics… How do we figure out what’s worth our time? Now there’s a method.

The Method – Health in the Real World unpacks the science and real-world application behind modern-day health. We speak with leading voices to help you make sense of your health, and we find out how we can live better now, and for longer.

Each episode, long-time friends Greg Potter and Charlie Edmondson will interview leading experts to put key health topics under the microscope, and unpack health questions through three lenses:
- The science: What the experts, data, and scientific research say.
- The practice: How to turn theory into habit and sustainable behaviour change.
- The experience: How the practice lives up to expectation in real life.

In an often chaotic world, we want to keep an eye on the long game: maximising your healthspan, not just your lifespan.

Whether it’s eating better, moving with intention, or getting quality sleep… We help you build good, evidence-based habits that stick. Let’s find out what works for you. The Method gives you the tools to chart your own path towards health confidence.

Expect deep dives into the science of health. We’ll cover topics like: supplements, brain health, personalised nutrition, biomarker tracking, zone 2 training, stress management, but also explore psychological wellness, the power of social connection, and good emotional resilience.
Whether you’re new to proactive health, or already experienced and looking for nuanced conversations and fresh insights, The Method will empower you to push what really matters when it comes to your health.
