Popular Actor Shocks With His Extreme Weight Loss Transformation

He wants to have only 5% body fat!

Beloved actor Yoon Shi Yoon has surprised fans and viewers with his intense body transformation, revealing that he currently maintains a body fat percentage of just 6.5 percent, with a goal of reaching 5 percent.

But this extreme level of physical conditioning isn’t just for show. It’s all part of his preparation for the upcoming SBS K-Drama Taxi Driver 3, where he will take on a role that demands a physically and emotionally drained appearance.

In a recent episode of My Little Old Boy, Yoon Shi Yoon opened up about his lifestyle and how he approaches work. For this role, he lost 10 kilograms and admitted that he’s aiming to look “sunken and hollow” to better match the character’s emotional state. The level of detail he’s applying to his preparation has impressed many, not just for the visual transformation, but also for the mindset that comes with it.

I want to give off a gaunt, hollow look… as if I’ve completely wasted away.

The actor also shared a rare look into his personal space and daily routine. Notably, his home doesn’t have a sofa—a deliberate decision he made to avoid falling into laziness.

I’m actually a very lazy person. That’s why I need a plan. I get energy from following a routine. The sofa is the number one reason people get lazy, so I got rid of it. I want my home to fully welcome and support me. No matter how busy I get, I never allow things to be messy.

His day starts at 7 AM with a schedule planned down to the minute. “If I don’t make a plan, I’m afraid I’ll waste the day,” Yoon admitted.

As anticipation builds for Taxi Driver 3, fans are eager to see how Yoon Shi Yoon’s hard work and transformation will translate on screen—and what kind of character could demand such commitment.
