History's weirdest fad diets
A government minister is the latest to warn people of the dangers of fad diets, but people have been following them for centuries. Why?
As early as the Greeks and Romans people have been dieting. But while it was largely about health and fitness back then, it's the Victorians who really kick started the fad diet.
"The Greek word diatia, from which our word diet derives, described a whole way of life," says Louise Foxcroft, a historian and author of Calories and Corsets: A History of Dieting Over 2,000 Years.
"Dieting back then was about all-round mental and physical health. People really got a taste for fad dieting in the 19th Century. It is during this time that things tip over into dieting more for aesthetic reasons and the diet industry explodes."
So what are the weirdest and unhealthiest fad diets from history?
