In Episode #224, I sit down with Dr Tim Spector to discuss eating to optimise your specific biology.
“There’s a middle ground, an interaction between the genes and the environment that doesn’t depend on genetics.”
When we place so much focus on population-level data for health outcomes, it can be easy to lose sight of the unique biology that defines the way each person interacts with food. Dr Tim Spector joins me today to discuss how personalised nutrition may be the key to unlocking the healthiest version of ourselves.
“All of us process our food differently, [which] adds to that individuality.”
Dr Tim Spector is a medically qualified professor of epidemiology, director of the TwinsUK Registry, and co-founder of data science company ZOE. He is ranked as one of the top 100 most cited scientists, having published more than 900 research articles. His current work focuses on the microbiome and nutrition, positioning him as an expert in the field.
“We’re gaining more knowledge each week about how important the microbe processes are.”
In today’s episode, we establish what personalised nutrition is and why it is so important. We discuss research on twins, exploring nature versus nurture; the role of the microbiome in health outcomes; and whether conditions such as obesity and Type 2 diabetes are genetic. Dr Spector also offers advice on adapting your diet to your specific needs.
Specifically, we discuss:

This episode adds important nuance to a broader conversation. As Dr Tim Spector says in this episode, individualised nutrition is another tool you can use to feel your best. It represents an important mindset shift in nutrition conversation and can help people feel more empowered in their food choices.
Nutrition science can be overwhelming, especially with so much conflicting information available. I hope you gained value from this conversation as we draw focus away from calories and towards other factors including gut microbes, nutrients, and food quality.
