Elsa Richardson uncovers the early history of the wellbeing industry and introduces Eustace Hamilton Miles, a diet guru who made his name selling health to Edwardian Britons. Reformers promoted the ‘simple life’, one that emphasised fresh air, exercise and the consumption of ‘sun-fired’ foods such as wholegrains, fruits and vegetables but this ‘simple life’ was also a highly profitable enterprise.

Elsa Richardson teaches on the history of the emotions and is a Chancellor’s Fellow at the University of Strathclyde, Glasgow. The Essay was recorded at this year's Free Thinking Festival with an audience at Sage Gateshead.
