Actor Lee Jung-jae has revealed the reason behind his extreme diet.

On June 3rd, during an appearance on "Sung Si-kyung's Meet and Greet," Lee Jung-jae shared, "I'm on a strict diet because I'm filming 'Squid Game.'"

Lee Jung-jae is set to appear in the upcoming Disney+ series "The Acolyte." He attracted attention at a promotional event for the series due to his noticeably slimmer appearance.

Sung Si-kyung commented, "You seem a bit thinner. Is it because of your current project?" Lee Jung-jae responded, "I've lost a lot of weight. While filming 'Star Wars,' I did a lot of martial arts training and exercises to portray a strong, force-using Jedi."

He continued, "These days, I'm filming 'Squid Game.' The concept involves getting thinner as the games progress, so I'm on a very strict diet to fit the role."
