Cold-pressed juices, quitting sugar, Paleo, hot yoga, mindfulness … if you embrace these things you will be happy, you will be well – just ask Instagram. Wellness has become a global mega-industry. But does any of this stuff actually work? Feeling exhausted, anxious and out of shape, journalist Brigid Delaney decides to find out – using herself as the guinea pig. Starting with a brutal 101-day fast, Brigid tests things that are meant to make us clean, lean and serene. Travelling the world, she tries colonics, meditation, silent retreats, group psychotherapy and oodles of yoga, working out what is helpful and what is just expensive hype. And she's documented it all in her new book, . Brigid Delaney is a senior writer for Guardian Australia. She has previously worked as a lawyer and journalist at the Sydney Morning Herald, the Telegraph (London), ninemsn and CNN. She is the author of two books: This Restless Life and Wild Things. ********** A quick note about supporting the podcasts!
