Orlando Bloom Says His 52-Pound Weight Loss Made Him Feel Like ‘a Horrible Person’

Orlando Bloom shares how his weight loss transformation for a role heavily impacted his mental health.

The 48-year-old actor recently opened up about losing 52 pounds for his role as a retired boxer in The Cut. He confessed on the Wednesday, Aug. 27 episode of This Morning that he was only eating tuna and cucumber leading up to the film’s production.

“I was just exhausted,” he said, noting that he had “no energy or brain power.”

“Just mentally, physically, I was hangry,” he continued. “I was a horrible person to be around.”

Bloom said he worked with nutritionist Philip Goglia, the same nutritionist Christian Bale used, and Goglia advised Bloom to reduce his meals from three to two.

“Suddenly, all these foods were being taken away from me, and my protein powder was the last one,” he added. “I was like, ‘No! Don’t take that one.’ Then basically I came down to [eating] just tuna and cucumber for the last three weeks.”

He explained that because his mental health was impacted, he also suffered from “paranoia” and “intrusive thoughts.”

The Pirates of the Caribbean star also said that Goglia would regularly check his blood. “We’re supposed to eat and sleep and take care of ourselves,” he continued. “It’s really a commentary on the lengths a person will go to have that second shot. I think that’s so relatable.”

He noted that while athletes are known to cut weight “on the regular,” actors tend to “take it to the extreme” in the short period before they star in the role. While filming, he would still do what he could to look his best on camera, Bloom said, recalling that he would be “lying down in between takes on set,” and then get up to do push-ups “to look a little bit bulkier.”

Although he was able to push through the “intense” diet, he doesn’t “recommend” it to “anyone at home.”

He previously told PEOPLE he was “excited by the challenge” of transforming himself for the role. He confessed that his lack of sleep caused such a mental toll on him, adding, “Turns out you can’t sleep when you’re hungry!”

In the upcoming film, Bloom stars as an ex-boxer who suffered a defeat that ended his career in the ring. Then, when he “trains for redemption,” a synopsis teases, an “obsession takes hold and reality unravels — and he may be spiraling into something far more terrifying.”
