Billie Eilish Opens Up About Her Weight Loss Journey and 'Gym Rat' Lifestyle: 'Feel So Much Better'
The "Bad Guy" hitmaker continued, noting to Lowe that at the time, she "started working out at a gym for the first time every day."
She added: "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."
In 2019, Eilish was memorably featured in Calvin Klein's ‘I Speak My Truth In #MyCalvins’ campaign, where she expressed her preference for oversized clothing.
She discussed her desire to prevent others from objectifying her body, using her attire to maintain her privacy as she gained fame during her teenage years. In a 2023 interview with Variety, the Grammy winner reflected on her career beginnings and style choices.
Eilish explained: "I wasn’t trying to have people not sexualize me. But I didn’t want people to have access to my body, even visually."
The "Everything I Wanted" crooner continued: "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."
Since then, the singer-songwriter has showcased her athleticism through gym selfies and red carpet events, choosing outfits that emphasize her toned figure.
Eilish's commitment to fitness has clearly paid off, and as fans have pointed out, she has grown more confident in her appearance. This transformation has inspired many devotees, who frequently express their admiration in the comments beneath her social media posts.
