What to expect

“This superb book is an essential guide to the wild world of internet health.” —Chris van Tulleken, author of Ultra-Processed People

When did we start trusting influencers over doctors?

You used to see a doctor. Now you go online.

Want to track your blood sugar? Your heart rate? Your sleep? You can. Need to focus? Want to lose weight fast? Everything is a click away.

But who is regulating this?

As hospital wait times grow ever longer and some patients are priced out of medical care altogether, influencers have filled the gap. From doctors promoting new therapies, to entrepreneurs selling solutions, these self-styled experts glow with good health and guarantee results.

But they are not familiar with our medical history. They don’t owe us a duty of care. And they’re rarely either qualified or impartial. So why do we trust them?

Critics Review

  • “This superb book is an essential guide to the wild world of internet health—a series of cautionary tales, brilliantly told.”

    Chris van Tulleken, author of Ultra-Processed People

  • “This book tackles one of the most important health issues of our time. It is brilliant, thorough and vital. Empowering for anyone who has ever come across health information, stories, or advice online—which is pretty much all of us.”

    Daniel M. Davis, Professor of Immunology at Imperial College London and author of Self Defence: A Myth-Busting Guide to Immune Health

  • “Bad Influence arrives at a moment when fascination with health, longevity, and ‘optimized living’ has never been greater…With a reporter’s eye and a scientist’s precision, Deborah dissects the interventionist claims of the wellness industry and exposes the shaky evidence underpinning it. Her diagnosis is uncomfortable but urgent: that those selling us control over our health may, in fact, be the ones making us sick. Bad Influence is a must-read for anyone who has ever turned to the internet in search of better health—and a timely warning about the seductive power of bad influencers.”

    Natasha Loder, Health Editor, Economist
