Don’t you just hate it when you accidentally lose a bunch of weight while filming a movie?

In a new interview with E! News, Olivia Munn revealed that losing 12 pounds was an “unintentional” side effect of preparing for her role in X-Men: Apocalypse.

“It was not intentional,” she said. “I was trying to learn how to do all of the stunts.”

Munn, 35, took on the challenge when she found out her stunt person had never done any martial arts or swordfighting – two areas in which her character, Psylocke, excels.

“She was very capable and very athletic, but she had never done any stunts before, and I had grown up doing Taekwondo,” Munn said. “This is Psylocke’s entry into this world. I’m not Jennifer Lawrence: If they don’t have it, they’re not gonna make sure to get it in there somehow. If there’s not a fight scene being shot, if they don’t have it, they’re not gonna use it.”

The actress continued: “If I wanted the fans to see Psylocke and get a good fight scene for her and for the fans, I knew I had to go do it myself. So I started training every day with Taekwondo and sword and the stunt and wire work and I just ended up losing 12 pounds just from working out every day.”

After filming finished, Munn admits she put back on a few pounds – but didn’t seem to mind.

“As soon as I finished, I went back to Green Bay, where my boyfriend [NFL quarterback Aaron Rodgers] was, and I literally just ate chips and salsa,” she said. “There’s a really great Mexican restaurant called Margarita’s, and I just massive chips and salsa and just ate that all day long until I fell asleep. And then I’d wake up and eat chips and salsa again.”

X-Men: Apocalypse hits theaters May 27.
