When it comes to "pleasing" trolls, Lena Dunham just can't win. 

Throughout her career, the "Girls" star has been called everything from a "cow" to an actual monster. 

Most of these cruel comments were aimed directly at her fuller figure. And even now, as she's losing weight through a health plan that helps control her endometriosis, the criticism is still pouring in. 

Dunham recently appeared on "The Ellen DeGeneres Show" to express her frustration.

She told DeGeneres that after years of dealing with fat shamers, she now has to contend with trolls picking her apart over her weight loss. 

“It’s just so crazy because I spent six years of my career being called things like ‘bag of milk’ on the internet," Dunham said.

“I was frustrated by it, because it really was evidence that as a woman in Hollywood, you just can’t win."

But Dunham refuses to let the haters affect her self-esteem.

“I also just never felt self-conscious about it,” she added. “I was like, anyone who’s going to take the time to say something negative about my weight on the internet I wasn’t particularly keen to impress anyway.”

She wants people to understand that she's not a "hypocrite" because she slimmed down.

“I had this experience of my body changing and I had all these people being like, ‘You’re a hypocrite, I thought you were body positive, I thought you embrace bodies of all sizes.’ And I was like, I do, I just understand that bodies change. We live a long time. Things happen."

Her weight loss was actually essential to her health and well-being.

"I had to adapt some new healthy lifestyle choices because I have endometriosis, and that's an illness one out of 10 women have," Dunham told DeGeneres. "It's a reproductive illness. It's chronic, and there's ways you can manage it through diet and exercise."

She continued, "So when I was getting all that flack for having lost weight, I was like, 'Actually, I'm just trying to take care of my body so that I can keep doing what I do."

But Dunham doesn't owe anyone an explanation: Her body is her body, at every phase and at every weight.

"Right now I'm struggling to control my endometriosis through a healthy diet and exercise," she wrote on Instagram last week. "So my weight loss isn't a triumph and it also isn't some sign I've finally given in to the voices of trolls. Because my body belongs to ME — at every phase, in every iteration, and whatever I'm doing with it. I'm not handing in my feminist card to anyone."
