Professor Tim Spector is one of the most cited scientists in the world and a leading expert in gut health, nutrition, and the microbiome.

In this conversation, we break down why much of what we’ve been told about food is wrong - from calories and dieting, to why two people can eat the same meal and have completely different biological responses.

We talk about the connection between the gut and the brain, how your mood and energy might be more shaped by what you eat than we've ever been taught, and why habits like flossing could even have an enormous impact on your risk of dementia.

Tim also explains how modern food systems are designed to keep us hooked, why willpower isn’t the issue, and what simple changes can actually make a difference.

This is a conversation about how your body really works - and what you can do about it.

Interviews that might just change your life. And if not…? You’ll probably enjoy them anyway.

While we're all trying to be better versions of ourselves, this podcast asks: 'what's truly possible?'

Project Possible, hosted by me, Rich Leigh, explores this with incredible guests from the world of business, sport, entertainment and academia.

Between the second and third series, I made the decision to go full-time on this show.

I sold my successful 10 year old PR agency after my youngest brother Jordan took his own life.

I realised that I needed to run towards passion and purpose, and my dream of sharing positivity and possibility as a career - this podcast is my effort to do just that. Subscribe wherever you watch or listen.
