On the June 22 episode of SBS’s "My Little Old Boy," actor Yoon Si Yoon took on an extreme water-cutting diet in preparation for his upcoming drama "Taxi Driver 3."
Yoon Si Yoon revealed his body stats: 177 cm tall, weighing 67.4 kg, with a body fat percentage of just 6.7%. Seo Jang Hoon commented, "At that level, it’s practically no body fat."
Previously, Yoon Si Yoon had shared, "I want to show a completely different physicality in 'Taxi Driver 3.' I’m aiming for a gaunt, sunken look, so I’m currently working on weight control."
Yoon Si Yoon explained, "Today is my 24-hour water-cutting day." He abstained from drinking any water and followed a "no-water diet," preparing completely dry dumplings made with dried tofu sheets and eating a meal of asparagus, known for its diuretic effect.
Three days before filming, Yoon Si Yoon intensified his workouts to increase sweat output and completed a full dehydration session in a sauna heated to 45 degrees Celsius. Like UFC fighters, he soaked in hot water for 20 minutes to further sweat and cut water weight, impressing those around him.
Spending the day as the "water-cutting king," Yoon Si Yoon achieved a miraculous result, losing 5 kg in just one day, dropping to 62.3 kg and 3.6% body fat. The other cast members were stunned, exclaiming, "That’s seriously incredible. Amazing."
Visiting a photo studio, Yoon Si Yoon said, "I wanted to test how I would look on camera in this state. I want to look sharp, with piercing eyes, showing a side of me I’ve never shown before." Seeing his completely transformed appearance, Shin Dong Yup praised him, saying, "You’re a total professional."
