J.Y. Park reveals 18-hour fasting is the secret to maintaining 9.2% body fat

Singer J.Y. Park is maintaining an extreme self-discipline regimen to deliver flawless stage performances. As revealed on the recent MBC broadcast of "Omniscient Interfering View," J.Y. Park has pushed his body fat percentage down to 9.2% this year, surpassing the 11% he recorded during last year's Waterbomb Festival stage. To achieve the physique he displays on stage, he is pushing himself through rigorous dietary management.

Extreme Management: Maintaining an 18-Hour Fast

J.Y. Park revealed that he maintains an 18-hour fasting period to reach his peak physical condition. While expressing how tedious, difficult, and hungry the 18-hour fast can be, he explained the physiological benefits of the process. He noted that once the fast exceeds 12 hours, Human Growth Hormone is secreted, providing a healing effect for the body. "I'm so sick of being hungry. I'm so sick of the hunger," he confessed candidly regarding the struggles of repeated fasting.

To soothe his intense hunger, he has chosen a combination of lemon juice, black coffee, and salt. On-site, he was seen drinking a mixture of lemon juice and salt to curb his appetite. He shared his routine, saying, "Lemon juice on-site, and my friends are black coffee, salt, and lemon juice." Adding that hunger actually aids his performance right before a show, he expressed confidence that being hungry leads to better results on stage, stating, "I perform much better when I'm hungry."

Perfectionism: Directly Involved in Costume Concepts

J.Y. Park also demonstrated extraordinary passion during the costume preparation process. Collaborating closely with his stylist, he directly contributes ideas for stage outfits, such as preparing neon-colored costumes designed to captivate the audience when paired with stage lighting. In particular, this year's outfits were designed to emphasize his physique, showcasing the toned body achieved through his 9.2% body fat. The intention was to create an intense neon effect that becomes mesmerizing when combined with the lights.

The details of the costume design were equally striking. The design, intended to highlight his body lines, delivered a visual impact on-site. The design was bold enough that the glimpses of his physique were even more prominent than intended—a result of J.Y. Park's own ideas developed alongside his stylist. The intense colors and design were so striking that some on-site reactions included, "It's blinding to the eyes."

A Perfect Physique That Needs No Body Makeup

On-site, admiration poured in as people observed his lean, flawless physique. By maintaining 9.2% body fat, he achieved a physical condition so perfect that no additional body makeup was required. His toned muscles and lean lines, which prompted reactions like, "There's no need for body makeup; his body is just too good," served as proof of his rigorous self-discipline.

J.Y. Park suggested that he has poured all his energy into this performance. With the remark, "Get ready again next year," he hinted that he will return to a new management regimen following this stage. His physique, perfected through this year's intense discipline, is more than just an outward appearance; it is the product of fierce effort to elevate the quality of his stage performances.
