Sydney Sweeney shares brutally honest weight loss journey for 'Christy'

Sydney Sweeney recently opened up her drastic transformation for her role in the boxing film Christy.

In a candid conversation with PEOPLE magazine, the 28-year-old actress revealed the strict regimen she followed to prepare for character, which helped her lose 30 pounds.

"I had to be really strict with myself," Sydney recalled, describing how she lost the weight for her latest project.

She continued, "When I was training, it was really hard to put on all the weight. I was eating so much food. Like, everything you could possibly imagine."

"And then I was downing protein shake after protein shake and taking a lot of creatine, which just makes you bloat," the Euphoria star added.

To get back to her pre-Christy shape, Sydney had to cut out all of that.

"When you stop working out and taking all your protein shakes, you lose muscle super fast," she explained.

The Anyone But You actress stated, "It's the first thing to go before fat. So, I dropped within two weeks.”

Christy, starring Sydney Sweeney and based on boxer Christy Martin’s true story, premiered at TIFF on September 5 and was released in the U.S. on November 7, 2025.
