People who suddenly start fighting the flab while they're in an apparently steady relationship are secretly preparing to drop their other half, the Daily Mail reported a study as claiming.



According to sociologists, happy couples don't worry about their expanding waistlines because there is less pressure to look attractive.

Thomas Klein, who studied the link between happiness and body weight, said the warning signs could include a sudden obsession with the gym or getting involved in sports and diets.



"When you are on the lookout for a new partner people try to be as thin and attractive as possible,' Klein, of the University of Heidelberg, said.



Klein added: "People in a relationship feel less pressure and often put on weight as they do not watch their weight so much."



Researchers studied more than 2,000 people aged between 16 and 55. Among the findings was that people in couples generally weighed more than single people hoping to attract a partner in a competitive dating market.
