The 24-year-old aspiring doctor has struggled with her own weight problem and suffered from bulimia - Davuluri lost nearly 30 kilos to get back in shape.
"People who've been overweight, especially women, feel like at a moment's notice we can go back to where we were," she told the Syracuse Post-Standard.
"It makes you more sympathetic, more empathetic. You don't judge. I've been there, and if I can pull myself out of where I've been, anyone can."
Bulimia is an eating disorder characterised by binge eating and then vomiting it out because of an extensive concern for body weight.
