“I’ve been completely changing the way that my life is involving fitness,” the Grammy-winning artist told Zane Lowe during an Apple Music interview in September 2024. “I started working out at a gym for the first time every day. And I know that’s a pretty — like a lot of people do that. But that was not a thing I did, and it’s become such an incredibly huge part of my life and it makes me feel so much better as a person and the way that I can move on stage now,” Billie continued.

Let’s dive into the timeline of Billie Eilish incredible weight loss transformation and see how she has evolved over the years.

2019: The Beginnings

In 2019, Billie rocked the stage at the Los Angeles stop of the iHeart Jingle Ball tour. That year, she explained the reasoning behind her love for baggy outfits. “Nobody can have an opinion because they haven’t seen what’s underneath,” the Grammy winner said as part of Calvin Klein’s ‘I Speak My Truth In #MyCalvins’ campaign.

“Nobody can be like, ‘she’s slim-thick,’ ‘she’s not slim-thick,’ ‘she’s got a flat ass,’ ‘she’s got a fat ass. ‘ No one can say any of that because they don’t know,” Billie added.

2020: The Evolution of Style and Comfort

In 2020, Billie matched her bright green loose T-shirt and long shorts with her hair streak while on tour. Reflecting on the early days of her career, she revealed, “I wasn’t trying to have people not sexualize me. But I didn’t want people to have access to my body, even visually,” in a 2023 interview with Variety.

“I wasn’t strong enough and secure enough to show it. If I had shown it at that time, I would have been completely devastated if people had said anything,” she added.

2021: Met Gala and Marilyn Monroe Vibes

The musician served up Marilyn Monroe vibes at the Met Gala in a flowing peach tulle gown. Billie said of her time as a platinum blonde, “I was really excited for the blond era — like, Blond Billie is gonna be so cool. But it did not go how I wanted it to go,” in a November 2023 interview with the Los Angeles Times.

“I completely had no idea who I was,” she recalled. “I came up with this whole aesthetic, and I just got swallowed up into it.”

2022: Embracing Comfort and Confidence

In 2022, Billie’s baggy wardrobe still applied during a gym session selfie. After posting a bikini photo in 2020, the “Happier Than Ever” singer told Dazed magazine, “I saw comments like, ‘How dare she talk about not wanting to be sexualized and wear this?’ It was trending. There were comments like, ‘I don’t like her anymore because as soon as she turns 18, she’s a whore.’ Like, dude. I can’t win … If there’s a day when I’m like, ‘You know what, I feel comfortable with my belly right now and I wanna show my belly,’ I should be allowed to do that.”

December 2023: Showcasing Transformation

Billie wore a fitting two-piece striped set that featured a floor-length skirt and oversized blazer with a plunging neckline. The ensemble highlighted her tiny waist. In a 2021 interview with Vanity Fair, the Los Angeles native sadly said about online discussions over her figure, “I thought that I would be the only one dealing with my hatred for my body, but I guess the internet also hates my body. So that’s great.”

2024: The Peak of Fitness and Fashion

The Oscar winner wore a form-fitting black corset dress over a long-sleeved white blouse to the 29th Annual Critics Choice Awards, showing how her weight loss in 2023 and commitment to hitting the gym had continued into the new year.
