A lot of the Fat Acceptance movement addresses this idea.
Thanks for the links! I was telling her to look into fat acceptance, as well as disabled feminist stuff, and feminism in general. Her concern was the size of this Facebook group she was invited to - about a million people signing up to tell all the "girls" they know that they're beautiful, without any critique of the use of the beauty myth as oppression - and so she wanted to set up an alternative and see if it goes anywhere. Which she's done. She's now contacting the press to see if she can get some interest going around this subject, to tie in with Valentine's Day.
Edited to remove a link I put up for a limited time, because of contact details.
