The inspiration for a Netflix series starring Celeste Barber, Wellmania is an in-depth, entertaining, laugh-out-loud-funny exploration of wellness culture.

Now with a new preface by the author.

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 a bit flabby, 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.

In monasteries and health farms, on hiking trails and massage tables, she asks, she asks, why do so many of us swing from indulgence to detox and back again? Is it possible to integrate good habits into your daily life? What does our obsession with wellness say about us? And why do you smell so bad when you haven't eaten in seven days?

Wellmania is the highly entertaining and occasionally dangerous exploration of one of the most fascinating trends in our culture.
