Sydney Sweeney is allowing fans to be voyeurs into her transformation journey.
The “Euphoria” star shared insight into how she gained roughly 30 pounds to portray real-life boxer Christy Martin in her new movie, “Christy” — and it included a diet heavily made up of fast food.
In two photos shared to her Instagram Story Nov. 10, Sweeney wore two different costumes — a military uniform and a blue oversized T-shirt and jeans — while on set of the drama. In one of the snaps, she’s eating an entire pizza pie herself, while in the other, she’s enjoying a personal order from Chick-Fil-A.
Reflecting on her efforts to transform into the athlete, she wrote atop the shots, “Trying hard to keep your calories up lol.”
However, a carb-intense diet isn’t the only lifestyle change Sweeney made for her part in the film, which hit theaters Nov. 7 and also stars Ben Foster, Merritt Wever and Katy M. O’Brian.

In a separate Instagram Story, the “Anyone But You” actress shared a video of herself doing “workouts between takes.” In the clip, Sweeney — wearing Christy’s white-and-red boxing uniform and curly-haired brown wig — performed some bicep curls with a pair of hot pink eight-pound dumbbells.
Indeed, the 27-year-old adopted a grueling fitness regimen ahead of stepping on set for “Christy.”
“I came onboard to play Christy, and I had about three and a half months of training,” she told W magazine in an interview published in June. “I started eating. I weight-trained in the morning for an hour, kickboxed midday for about two hours, and then weight-trained again at night for an hour.”
By the end of her 30-pound transformation, Sweeney admitted she “didn’t fit in any of my clothes.”
“But it was amazing,” she clarified. “I was so strong, like crazy strong.”
