Episode notes

We all kind of know someone who seems to not have too much trouble at all staying thin, and then some one else who is. How much of that could be down to genetics versus other factors like the microbium? I'm sure it's a mixture, a but there's deftly some genetic component, because we all know families where everybody stays skinny and they can see to overy. But i think there's colla middle ground, an interaction between the genes and the environment, and don't depend on genetics.

In Episode #224, I sit down with Dr Tim Spector to address the significance of eating for your specific biology. 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.

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.
