Well, thank you all for your kind words.
This experiment (as she calls it) was wonderful, her self esteem grew a lot, and now she really knows that a lot of people see beauty on the curvage girls. She's embracing her body, eating without worries, no matter if she gains or loses (personally and she knows it, I prefer if she gains, it's like getting more of her).
Anyway, on behalf of her and me, thanks.
By the way she's from Colombia.
