Today’s bonus guest is Dr Chris van Tulleken, he's the author of the bestselling book Ultra Processed People, an infectious diseases doctor and broadcaster. Now for anyone who’s been listening to Big Fish for a while, you’ll know that this book absolutely changed my life. It’s an eye-opening exploration into ultra processed food and why we can't stop eating it. He looks at how this industrially processed food is designed and marketed to be addictive, why exercise and willpower can't save us and what UPF is really doing to our bodies and our health. I absolutely loved this conversation with Chris - you’ll find it utterly fascinating.

Frankie Bridge is best known for her pop career - she was a member of one of the UK’s most successful girl bands, The Saturdays, and pop group S Club Juniors, which she joined at just 12-years-old. She’s also the Sunday Times bestselling author of OPEN: Why Asking for Help Can Save Your Life and GROW: Motherhood, Mental Health and Me. In this episode we talk about the power of self-belief, her experience of being a child star and its impact on her life, and the challenges of comparison when you're in a girl band.
