On the June 22nd episode of SBS’s 'My Little Old Boy', viewers got a raw look at his extreme preparation. Standing at 177cm and weighing 67.4kg with only 6.7% body fat, Yoon Si Yoon was already in top shape. Still, he wanted a gaunt, hollow look for his new character, so he embarked on a 24-hour water fast—a method so intense that even his saliva dried up. Fans and fellow celebrities alike were stunned by his discipline and the visible transformation, with his face growing noticeably sharper and more shadowed.

Inside the Extreme Routine: Waterless Diet and High-Intensity Training

Yoon Si Yoon’s method wasn’t just about skipping water. He also adopted a 'waterless diet,' eating only dehydrated foods like dried tofu dumplings and asparagus, famed for their diuretic properties. While eating, he joked about the dryness, using self-hypnosis to push through the discomfort. His day was packed with high-intensity workouts, designed to sweat out every last drop of water. This routine, inspired by professional fighters, included running, strength training, and even setting his home gym to high temperatures to maximize dehydration.

The Final Push: Sauna and Complete Dehydration

Three days before filming, Yoon Si Yoon took things to another level. He entered a 45-degree sauna, soaking in hot water for 20 minutes to induce complete dehydration. This method, commonly used by UFC fighters for rapid weight cuts, left him dizzy and exhausted. Despite the physical toll, he continued with household chores, impressing the production staff and viewers with his relentless work ethic. By the end of the day, he had dropped to 62.3kg and achieved a body fat percentage of just 3.6%.
