At one point, Kate Moss was almost as famous for her wild partying as she was for her modeling career, but at 45 years old, the British supermodel has ditched her bad habits for a healthier lifestyle — and she looks amazing.

The star has spent 30 years in the modeling industry, staying at the top of her game while working and playing hard. These days, however, she's in a new phase of her life. Moss has hung up her party shoes and overhauled her health, swapping alcohol, cigarettes and junk food for yoga, juicing and salads.

Exercise: 'I Actually Started Working Out'

Moss and exercise never used to mix. In fact, the model — who was discovered at age 14 — used to feel physically sick at the thought of working out. She once admitted to The Guardian: “I’ve never been a gym bunny or anything like that. I was always, like, ‘Ugh.' It made me feel ill.”

And yet now Moss doesn’t just do it for her health; she does it because she likes it. “I’ve actually started working out, I’m really quite into it,” she told The Guardian, adding the gym makes her feel “really good."

“I worked out for an hour every consecutive day for a couple of weeks and it was enough that I really started to see the benefits, which I’d never really done before. I always thought, ‘This is agony, I’m not coming back. This is torture.' But this time I just kind of pushed through. I honestly lost an inch off my waist in about 10 days. Now I really enjoy it."

Yoga: 'I Do It Every Day’

Moss doesn’t just work up a sweat on the treadmill; she also Zens out by practicing yoga on a daily basis. “I’ve learned to take care of myself a bit more,” she told Harper's Bazaar. “I do yoga every day.”

Moss has yoga teacher and health guru Nadia Narain to thank for putting her through her mindful paces. Moss has heaped praise upon Narain — who has a host of celebrity clients, including Reese Witherspoon and Rachel Weisz — and gushed, "Nadia's teaching is food for the soul, and her classes for me feel like home.”

Body Image: ‘I Was So Thin’

While genetics plays a large part in Moss’ slender, 5-foot-7 frame, she admitted there was a phase during her modeling career when she was too thin. “I was never bony-bony. But I remember thinking, 'I don't want to be this skinny,’” she told Interview Magazine. "I didn't eat for a long time. Not on purpose. [I was constantly] doing shows and flying economy... nobody ever fed me.”

Moss added that she looked in the mirror and didn’t like what she saw. "I was so thin! I hated it.” That's why the supermodel is relieved the modeling world is now embracing more shapes and sizes.

“There's so much more diversity now, I think it's right," she told Megyn Kelly during an interview with NBC. "There's so many different sizes and colors and heights. Why would you just be a one-size model and being represented for all of these people?”

Diet: 'I Try to Eat Healthily’

Despite decades of partying, Moss has put her boozy days behind her. Her younger sister, Lottie Moss, confirmed to the Mail on Sunday: “Kate is not drinking anymore. She is fully clean.”

In addition to her sobriety, she’s found a passion for healthy eating, too. “Food is really important. I try to eat healthily,” Moss told The Guardian. “I do cook, but not as much as I’d like to because I’m busy, but I cook a good roast. I do good breakfasts — eggs are my forte. I really enjoy food, proper food, but I do try to eat more healthily than I used to."

And she's noticed the benefits of her healthier diet. "My skin looks better when I eat well, too. Obviously if you eat all that grease, skin just doesn’t look as healthy. I’ve really noticed an improvement since I’ve been more ‘on it’ with food, like eating salads and all that stuff . I never used to really eat salads. And now I’m like, juicing!” she said.

Beauty Regimen: 'I'm Not Obsessed'

Considering she’s a supermodel, Moss’ beauty routine is remarkably low maintenance. Although she spent years sunbathing on yachts or on the beaches of Ibiza, Moss told Harper's Bazaar her skin has "somehow held up."

But now, she's definitely taking better care of it. “Don’t get me wrong, I love beauty products more than ever — as you get older, you have more to hide —but I’m not obsessed,” she said.

Moss is also the creative director for Japanese beauty brand Decorté, and the brand's products make up her simple morning skincare routine. “My daily routine is quite simple,” Moss told The Evening Standard. “I wash my face with Decorte’s Clean & Pure Foam Wash, then add a few drops of Vitality Tincture to the brand’s AQ Meliority Intensive Cream to really hydrate my skin.”

Self Care: ‘You Have to Put in the Work’

It certainly looks as though Moss’ new lifestyle is working for her, and she’s happy to put in the effort to keep it that way. “The bad things I have done usually take their toll,” she told Harper's Bazaar. “I’ve been quite lucky in that respect, but you have to put in the work."

Of her new, healthier lifestyle, Moss told Megyn Kelly, "I'm a good girl now." And those habits extend beyond eating well and exercising. "I go to bed, I drink lots of water, not too much coffee, and I’m trying to cut down on cigarettes. I take care of myself now."
