France have proposed a new law where it is illegal for modelling agencies to hire models who are underweight and malnourished this law would be set based on a models BMI as well as this magazines must state if an image has been photoshopped.
If this law isn't obeyed they risk a six month prison sentence and a fine. However I find that using only your BMI won't work as some people are naturally skinny due to high metabolism, they should also consider the models mental state along with the symptoms of anorexia.
I think this is just a step to improve views on models in the eyes of young girls who aspire to be them. I think at the moment you will struggle to see it making a difference but as time goes on I think you will see a bigger outbreak of the extreme measures these models go to to stop agencies to hire these models. On the other hand I think this has always been an issue and a lot of the fashion industry want skinny models and I feel they will still find a way of bending the rules to allow these girls to model.
