Healthy bodies "have got flesh on them, they're soft, they're athletic, they're all sorts of things," says Field, who is encouraged by strides some of the outspoken younger actresses and musicians are making in changing up these stereotypes.
"Some of the young actresses today, like Jennifer Lawrence and Amy Schumer, are telling the media and advertising and whomever else to go f--- themselves," she says. "I could not applaud them more. And the only reason they're heard is because they're all so frigging talented."
"Look at Adele," Fields adds. "She's saying, 'Hey, you know what? This is what women look like.' Wow!"
