With his chiselled good looks it is hard to believe that Dallas Buyers Club star Jared Leto turned 50 on Boxing Day.

The actor and musician could pass for half that age and wowed fans once again last night at a special fan screening of his film Morbius in Berlin.

He channelled a 70s vibe with a flared suit, a mesh shirt which showed off his toned physique with his signature flowing locks and shades helping him defy the years.

But the House of Gucci star credits his dedicated healthy lifestyle of almost daily workouts and a mainly plant-based diet for helping to hold back the hands of time.

When asked about his youthful appearance by Rolling Stone in 2016, he credited his plant-based eating regimen.

“It’s probably just down to sleep and diet. If you travel long haul a lot or don’t sleep much, it’s not going to last very long, that’s for sure,” he said at the time.

“I’m pretty healthy so I think that helps a lot. I’ve been that way for a long time – 20 solid years of eating vegetarian/vegan and taking care of myself. That probably helps the preservation process.”

But he also revealed he is prone to the odd cheat - sometimes eating fish or dairy. “I’m actually a ‘cheagan’ — a cheating vegan,” he clarified to the publication. “I don’t eat meat ever. But if someone’s mom made a cookie and handed it to me, I’d probably take a bite, or if I’m in Alaska and there’s wild salmon out of the river, I’d probably eat it.”

The Joker star has managed to maintain his physique throughout his career - unless a role demands change.

He gained 70lbs eating bucket loads of ice cream, olive oil and soy sauce to play John Lennon's killer Mark David Chapman in the film Chapter 27.

He famously dropped down to a painful 116lbs to play a transsexual woman battling AIDS in the film Dallas Buyers Club by fasting for a whole month. The role earned him a Best Supporting Actor gong at the Oscars.

The rest of the time health is his goal mixing up yoga, hiking, climbing and cycling with regular gym workouts.

But in an interview with Men's Health, he said that looks really don't matter.

"Really, honestly, at the end of the day, it doesn't really matter," he explained of people's obsession with his youthful appearance, noting that Hollywood’s fixation on youth can be quite toxic.

"People started talking about my age and that sort of thing ten years ago," he said. "As you get older, people start saying, ‘Ah, you're still young.’ And then there's this age where they go, Really? "

"Unfortunately, I'm not getting movie roles where I play, like, 'a rather young-looking old man,'" he said. "Maybe I'm doing something wrong — not taking advantage of it enough. It just doesn't matter. You can be 30 years old and live an amazingly exciting, interesting, fulfilling life, or you can be 60 and having a crisis."
