This wasn’t just any regular diet. Yoon Si Yoon went full commitment mode for his upcoming role in “Taxi Driver 3.” The 177-cm tall actor started at 67.4 kg with only 6.7% body fat. That’s already super lean! But he wanted to look even more gaunt and sharp for his character.

Yoon Si Yoon Weight Loss Method Was Extreme

The water-cutting diet he used sounds intense. For 24 hours straight, Yoon Si Yoon didn’t drink any water at all. Zero. Nada. He ate completely dry dumplings made with dried tofu sheets. Plus, he munched on asparagus because it helps your body get rid of extra water.

But that’s not even the wildest part. Three days before his big weigh-in, he cranked up his workouts like crazy. Sweat was pouring off him during every session. Then came the sauna torture – sitting in 45-degree heat to sweat even more.

Like those tough UFC fighters, he soaked in super hot water for 20 minutes. Talk about dedication! Everyone around him was amazed by his commitment. One cast member said his discipline was “seriously incredible.”
