Self-scrutinising fictional heroines could be bad for your health.
Research by Virginia Tech found that reading "chick lit" books in which the protagonist worried about her weight made women uncomfortable about their own body image.
It looked at "the effect of protagonist body weight and body esteem on female readers' body esteem" and concluded that "scholars and health officials should be concerned about the effect chick lit novels might have on women's body image".
The report's authors took passages from two chick lit novels in which the protagonists have "healthy body weight" but "low self-esteem".
They then adapted the text from chapters of Something Borrowed and Dreaming in Black and White into nine versions in which the heroine's self-body image was distorted. One variation read "I'm 1.6m, 63.5kg and a size 6", and another, "I'm 1.6m, 47.6kg, and a size 0".
