Actor Yoon Si-yoon revealed a remarkable transformation through a 6% body fat ultra-low diet on 'My Little Old Boy.'
The SBS entertainment program 'My Little Old Boy' aired on the 1st, showcasing Yoon Si-yoon as he visited the gym early in the morning ahead of his return to the drama 'Taxi Driver 3.'
Appearing with a gaunt face, he said, "I want to give off a gaunt feeling, so I'm currently controlling my weight," and noted, "I have lost 10 kg, and my body fat percentage is 6.5%. My goal is 5%." Seo Jang-hoon expressed surprise, saying, "Kim Jong-kook is at 9%, and Ronaldo is at 7%, but 5% is nearly no fat at all," and when Yoon Si-yoon revealed his defined six-pack, Shin Dong-yup exclaimed, "I want to live with that body for just one day."
Yoon Si-yoon, who has become so gaunt that his youthful image has faded, stated he is undergoing extreme weight management, saying, "I am currently at 6%, but I am adjusting day by day to lower it to 5%." He had lost more than 4 kg during his language study in the Philippines last year. At that time, people remarked, "His jawline has regained definition, and the reactions were positive."
That evening, Yoon Si-yoon finished a simple meal of 'three finger foods' and satisfied his hunger by only savoring the scent of whiskey. In fact, he did not drink the whiskey but dropped a few drops on his tongue before immediately spitting it out. Regarding this, Yoon Si-yoon said, "Robert Downey Jr. enjoys only the scent during his works. I received help from that," and explained, "Alcohol interferes with body fat management."
He continued, "I've been abstaining from alcohol for six months. Because of that, my body fat percentage has dropped below 10% for the first time," and shared, "I have a lazy personality, so if I don't decide on this, I become complacent. Given that I'm receiving a lot of love at a young age and am in a good environment, living recklessly would bring me a big sense of guilt."
The thorough self-management of Yoon Si-yoon wowed the 'My Little Old Boy' MCs, who remarked, "Even Jong-kook would be envious," and viewers were deeply impressed by the actor's passion and sincerity.
