People with anorexia have a distorted body image
The brain naturally distorts body image - a finding which could explain eating disorders like anorexia, say experts.
Scientists at University College London discovered people tend to think that their hands are wider and their fingers are shorter than they truly are.
They say the confusion may lie in the way the brain receives information from different parts of the body.
Distorted perception may dominate in some people, leading to body image problems, a US journal reports.
Susan Ringwood, chief executive of the eating disorders charity Beat, said: "We know that one of the features of anorexia nervosa can be distorted body image.
"People affected can truly believe that they are grossly fat, even when they are dangerously underweight.
"They are able to judge other people's bodies quite accurately and would describe someone else the same size as themselves correctly, but still not be able to do that about their own weight and shape.
