Demi Lovato
Along with being vocal about her struggles with addiction and an eating disorder in the past, plus advocating for mental health awareness and reform, former Disney Channel star Demi Lovato has never been afraid to address the issue of body shaming. And that's whether it's coming from Internet trolls or the media.

But sometimes, her choice of response to body- and fat-shamers is also no response at all. Lovato told Glamour in 2016, "If somebody calls me fat, even in a vulnerable moment, I laugh to myself and think, I’m doing everything I can, so there’s nothing I can do about it. I don’t have a six-pack. Maybe I don’t even want a six-pack. It doesn’t sound very appealing."
