Billie Eilish's weight-loss journey has stirred quite a buzz. But behind her transformation lies a darker tale.

As a fitness trainer and holistic nutritionist, I believe it's crucial to approach weight loss from a place of positivity, not negativity.

And after researching her interviews, social media, and celebrity chatter, here's the scoop on Billie's weight loss.

Let’s get started.

Billie Eilish’s Weight Loss Journey

A photo of Billie in a green tank top went viral, sparking public interest.

With limited images of her in form-fitting attire, the internet had a field day commenting on her body. Negative feedback and her own self-image issues drove her to shed pounds.

But her dedication to health and self-care at such a young age is commendable.

Her Battle With Pills

In a candid 2021 Vanity Fair interview, Billie Eilish shared her challenges with body image, echoing the struggles I witnessed among young people during my initial years as a fitness trainer.

Billie's early aspirations in dance were derailed by a severe injury—a torn growth plate fracture in her childhood—which may have played a role in her subsequent weight gain during her teens. This setback pushed her toward unhealthy measures that are ill-advised for a developing body.

At just 12 years old, she turned to weight-loss pills, a decision she later recounted as being psychologically overwhelming.

“I wasn’t really eating. I was, like, starving myself. I remember taking a pill that told me that it would make me lose weight and it only made me pee the bed — when I was 12.”

Her Current Fitness Goals

In a new interview, Billie declared her new gym rat status. It's a title I proudly wore during my early fitness days, understanding the dedication it requires.

So this year, Billie commented that she’d been spending more time in the gym “pumping iron.” Her reason for this also has to do with the physical intensity demanded by her musical performances.

Having suffered injuries in the past, Billie mentions that she now works out to strengthen her muscles and prevent future injuries.

Diet Routine and Principles

There’s not much revealed about Billie Eilish’s diet routine, except that she currently follows a plant-based diet. From my own year-long vegan experimenting, I can tell you—it's no walk in the park!

Having been raised vegetarian all her life, Billie went vegan in 2014.

Her go-to foods are vegan burritos, tofu, and ramen [1]. And while Billie hasn’t attributed her weight loss to the vegan diet, it’s safe to say that making healthy vegan choices could’ve helped her drop extra weight.

Combating Disordered Eating

Eating disorders are among the most harmful culprits in the pursuit of weight loss. If you're facing challenges with body image or eating habits similar to those Billie Eilish has discussed, it's important to reach out for professional support [2].

To further support a healthier lifestyle, consider the following:

  • Eat a Balanced Diet: Prioritize a diet rich in protein and fats and low in carbs to burn fat more quickly, as suggested in a 2014 study published in the Nutrition & Metabolism journal [3]. And more importantly, ditch the junk food; it's a mood killer [4].
  • Drink Up: Drinking water may enhance satiety, according to findings from a study in the Clinical Nutrition Research journal [5]. Yet another reason to stay hydrated is the positive impact water has on your emotions [6].
  • Sleep Tight: A study from JMRI Mental Health states that quality sleep aids weight loss, muscle recovery, and mood [7]. So, make sure to catch those Zs.
  • Natural Fat Burners: These could complement your weight loss journey, curbing cravings and boosting energy.


How Does Billie Eilish Keep Fit?

Billie Eilish keeps fit by going to the gym every day. Although she hasn’t publicly revealed her workout routine, it’s safe to assume she does cardio every day and eats a balanced diet.

Why Does Billie Wear Loose Clothes?

Billy wears loose clothes because she doesn’t “want the world to know everything about” her. She doesn’t want people making comments on her body type, and wearing big baggy clothes is the best way for her to hide her body.

Has Billie Eilish Revealed Her Workout Routine?

No, Billie Eilish has not revealed her workout routine. Following the transformation, Billie Eilish’s fans and the media swarmed her with questions about her workouts.

Taking the Positives From Billie Eilish’s Weight Loss

Billie Eilish’s weight loss journey may have started out on a bad note, but it seems that her relationship with fitness and losing weight is in the right place today. It has sparked a positive transformation in her relationship with her body, promoting self-acceptance and confidence about body image.
