"It’s not good for me to see pictures of myself every day," she shared.
"It’s only happened a few times, and I’m not in any way proud of it, [but I'll see] a picture of me where I feel like I looked like my tummy was too big, or... someone said that I looked pregnant... and that’ll just trigger me to just starve a little bit – [to] just stop eating."
Taylor said she would often feel like she might to pass out during performances, would make a list of everything she put in her mouth each day and exercised constantly.
"I would have defended it to anybody who said 'I’m concerned about you,'" the You Need To Calm Down singer continued.
"I don’t think you know you’re doing that when you’re doing it gradually. There’s always some standard of beauty that you’re not meeting. Because if you’re thin enough, then you don’t have that ass that everybody wants, but if you have enough weight on you to have an ass, then your stomach isn’t flat enough."
"It’s all just f---ing impossible."
Speaking to Variety magazine about why she included her eating disorder struggles in her documentary, Taylor explained:
"I didn’t know if I was going to feel comfortable with talking about body image and talking about the stuff I’ve gone through in terms of how unhealthy that’s been for me – my relationship with food and all that over the years."
"I’m not as articulate as I should be about this topic because there are so many people who could talk about it in a better way. But all I know is my own experience."
"I think I’ve never really wanted to talk about that before, and I’m pretty uncomfortable talking about it now. But in the context of every other thing that I was doing or not doing in my life, I think it makes sense [to have it in the film]."
