Thinness and obesity: it's in the genes

Study suggests 'genetic advantage' keeps some people slim and healthy

As many people have long suspected, the genetic dice are loaded in favour of thin people when it comes to staying slim.

Researchers at the University of Cambridge have discovered that they have a genetic advantage over their overweight friends who live and eat in the same way that they do.
