The RCP asked the media to stop promoting unhealthy body images and "glamorising" eating disorders.
It has asked the government to set up a new ethical editorial code and urged the media to use more diverse body shapes and stop using underweight models.
The RCP also argued that articles that criticise the bodies of celebrities can make readers more dissatisfied with their own bodies. It has proposed a scheme which tells the reader when an image has been digitally manipulated to make models appear perfect.
Liberal Democrat MP Jo Swinson is starting a parliamentary motion this week in support of the RCP.
