New Israeli law bans underweight models in ads | ajc.com, but basically what the article says is that if a model has a BMI below 18, she can't be shown in advertising, that models have to provide medical documentation that they're not malnourished, and that it must be disclosed if photos have been altered.
Wow, big step!
