The 27-year-old made the comments as she recalled people being left “shocked” by her refusal to diet for roles, especially at the beginning of her career.
She explained: “Body image for women is a major thing.
“From the moment you start growing thighs and bums and boobs and all of it, everything starts changing. And your relationship with food starts changing.
“I had a weird chapter at the beginning of my career, but that was because I wasn’t complying. I think that was confusing to people, especially in Hollywood.”
She added: “Women in Hollywood, especially young women in Hollywood, are obviously putting themselves in all these ways in order to get whatever opportunity that they need to get because that’s just the way that it’s been.
“When I went, and I did that project it was expected that you would be on whatever diet you needed to be on and for me that was shocking because I’d never done that before.
“It’s not to say other people can’t do that but I think I definitely put my foot down in that aspect. I love food.”
Her latest comments come after she hit back at trolls who criticised her for going braless in a sheer gown at the Valentino fashion show in Rome in July.
At the time, Pugh spoke out against remarks she received from “vulgar” men and those who chose to “publicly destroy a woman’s body”.

Reflecting on the criticism she received, the Little Women star said the response she received over her fashion choices proved that there is still “so much more work to do” in this month’s Vogue.
She told the outlet: “I’ve never been scared of what’s underneath the fabric. If I’m happy in it, then I’m gonna wear it.
“Of course, I don’t want to offend people, but I think my point is: How can my nipples offend you that much? It’s very important that we do this.
“I know that some people might scoff at me saying that, but if a dress with my breasts peeking through is encouraging people to say, ‘Well, if you were to get raped, you would deserve it,’ it just shows me that there’s so much more work to do.”
