Demi Lovato shares dramatic before-and-after photos of her eating disorder recovery.

When she's not making music, Demi Lovato is a mental health warrior, keeping it super-real with her fans about living with bipolar disorder, and recovering from addiction and an eating disorder. The 25-year-old star first sought help at 18 and is now five years sober and still working on her body image and food issues.
