The 30-year-old Girls creator stopped by The Ellen DeGeneres Show, airing Wednesday, where she talked about being criticized for losing weight. Dunham admits she's "frustrated" by some people's response, especially since she was used to being called cruel things on the internet precisely because of her weight.
"It's just so crazy because I spent six years in my career being called things like 'bag of milk' on the internet ... and 'baby cow, aging cow' ... and I just never felt self-conscious about it," Dunham says. "Anybody that was going to take the time to say something negative about my weight on the internet wasn't someone I was going to particularly be keen to impress anyway."
"But then I had this experience of my body changing, and I got all these people saying, 'You're a hypocrite. I thought you were body positive. I thought you were a person embracing bodies of all sizes,'" she continues. "And I was like, 'I do,' I just understand that my body's changed. We live a long time, things happen."
Dunham points out the double standard women in the public eye go through.
"I was frustrated about it because it really is evidence that as a woman in Hollywood, you just can't win,'" she says.
