Red Velvet’s Joy Steals Hearts with Her “Blood Sugar Diet” Reveal – Tops Ratings on “I Live Home Alone”

Red Velvet’s Joy showcased her unique blend of expertise and charm on the April 11 episode of MBC’s “I Live Alone,” leaving viewers both impressed and moved by her honest and relatable approach to self-care.

According to Nielsen Korea on April 12, the broadcast recorded a 5.0% household viewership rating in the Seoul metropolitan area ranking No. 1 in its time slot and across Friday entertainment programs. Among the key 2049 demographic, the show achieved a 3.3% rating, again securing the top spot.

“Best 1 Minute” – Joy’s Viral Blood Sugar Diet

The show’s most-watched moment aired at 23:33, when Joy revealed her meticulously curated “blood sugar diet.” The diet included lemon water in the morning, peanut butter, peeled apples, high-protein soy milk, and cheese, highlighting her focus on both nutrition and glycemic index. This segment pushed ratings to a peak of 5.9%.

Living alone for six months, Joy’s home offered a delightful duality, part stylish “SNS zone” filled with aesthetically curated furniture and personal touches, and part “real-life zone” with everyday clutter that made audiences smile.

Joy also wowed viewers with her over 3-hour-long self-care routine, including stretching, skin care, meditation, and home treatments she’d researched online. Her passion for health and self-love earned her the nickname “Dr. Joy” from her fellow Rainbow Club members.

Joy opened up, saying, “I envy people with naturally slim builds. I wish I could be born with one in my next life.” She added, “In my 20s, I cared too much about how others saw me. That caused a lot of stress. When I shifted focus to taking care of myself, not for others but for me, my mental health and body improved.”

Real Friendship with IVE’s Rei

Joy also spent time with her close friend IVE’s Rei, offering heartfelt advice as Rei shared her concerns. Their endless chatter and spontaneous content-making session, including a short-form take on the viral “Exploding Guinea Pig Challenge,” showed off their fun chemistry. Joy even prepared a gift for Rei, melting hearts with her thoughtfulness.

Joy concluded, “There’s still so much I don’t know. Every day feels like a tree ring building up inside me. I don’t think I should ever stop learning about or caring for myself. And it’s honestly really fun.”

Jun Hyun-moo’s Battle with Laryngitis

The episode also featured Jun Hyun-moo, who was battling severe laryngitis. Struggling alone for a week, he leaned on fans’ supportive comments on social media for comfort. Despite eating only powdered grain meals, he managed to cook up healthy konjac noodles and ramen with vegetables. Even while fighting illness, he stayed committed to his recovery.

His friends Lee Joo-seung and NCT’s Doyoung gave conflicting advice cold vs. hot food which led to some comedic moments. Lee Joo Seung even personally drove Jun Hyun-moo to the hospital, deeply moving him. Later, Hyun-moo sent a coffee and snack truck to the set of Lee Joo-seung’s drama to return the favor.

After receiving IV treatment and devouring a hearty bowl of pork bone stew, Jun Hyun Moo was visibly revived. Fellow Rainbow members were relieved to see him back to his usual healthy self.

Coming Up Next Week

Next week’s preview teased the return of Code Kunst, who revisits his alma mater as a superstar, and Danny Koo, showing off his “super sexy” new routine, heightening anticipation for another exciting episode of “I Live Alone.”
