[Edaily Starin YUN GI BACK Reporter] At this point, it’s like “reversing biological age.” Actress Uhm Jung-hwa (57) performs her own stunts in movies, while singer Park Jin-young (54) delivers a powerful performance on the Waterbomb stage wearing a mesh outfit. These two, who naturally elicit exclamations like, “Are you really in your 50s?” recently revealed their personal health secrets on a TV show. One follows a “low-sugar diet,” while the other embraces an “organic lifestyle.” Though their approaches differed, they shared a common thread: minimizing strain on the body and consistently sticking to their own routines for decades.

Eom Jung-hwa appeared on KBS1’s “Morning Plaza” on the 4th and revealed that during a health checkup last year, she was told her biological age was in the early 30s.
“I’ve been cutting back on carbohydrates and sugar as much as possible for several years now, and my physical condition has definitely improved,” she said. “Every time I get a blood test or physical exam, I’m told my biological age is getting younger and younger.”
Currently, she follows a one-meal-a-day regimen while ensuring she gets enough protein and vitamins. In the morning, instead of coffee, she drinks warm water with salt or consumes lemon tea and olive oil. “I do get sugar cravings sometimes, but once you get into the habit of not eating it, you naturally crave it less,” she said, citing a low-sugar diet as the key to her health management.
This self-care extends to her work as well. In the movie “Okay Madam 2,” which opens on the 13th, Uhm Jung-hwa performs most of the action scenes herself, demonstrating her unwavering physical stamina.

Park Jin-young’s philosophy on health is slightly different. He recently revealed his own health management principles on MBC’s “Omniscient Interfering View,” stating, “It’s more important to avoid unhealthy foods than to eat healthy ones.”
Having maintained an organic diet and lifestyle for over 20 years, he is known for his meticulous approach—not only does he follow a vegetable- and fruit-centered diet, but he also uses certified organic products for everything from cosmetics to toothpaste, shampoo, and laundry detergent. In the past, when Suzy, a singer under JYP Entertainment, was suffering from allergies, he even studied the issue himself to advise her on how to manage it.
The results are evident in the numbers. Park Jin-young stated, “My body fat percentage was 11% during last year’s Waterbomb, but I’ve lowered it to 9.2% this year. This is my best physical condition since turning 25.” He went on to express confidence, stating, “The most important thing about this outfit is my physique,” and indeed, at last month’s ‘Waterbomb 2026,’ he drew attention by delivering a powerful performance while wearing a mesh outfit.
The secret to performing action scenes and dominating the Waterbomb stage even in his 50s wasn’t anything grand. Rather than adding one more thing that’s good for his body, he gradually eliminated one thing at a time that put a strain on it—and maintained that habit for decades. Ultimately, the secret to “reversing the aging process” wasn’t a special diet, but rather unremarkable consistency.
