Every girl has probably gone through a period when stress makes her desperately crave high-calorie foods, only to realize her body has quietly changed. AKMU member Lee Su-hyun, who had been going through a severe slump, recently returned to the public eye looking energetic and noticeably slimmer. It’s truly so wonderful to see her looking so radiant. This remarkable transformation isn’t simply about a lower number on the scale; it’s an inspiring journey of rediscovering balance in body and mind.

Breaking free from binge eating and a slump: How did AKMU’s Lee Su-hyun make up her mind to lose weight?

For a time, Lee Su-hyun admitted that she lived like a shut-in, caught in a vicious cycle of binge eating due to poor mental health that caused her weight to rise sharply. When she recently appeared with a new look, speculation even arose over whether she had relied on a well-known weight-loss drug. In response to these false rumors, she addressed them head-on on social media and firmly denied using any medication.

Her courage in facing the public so openly deserves praise. She candidly admitted that the only way she lost weight was by watching what she ate and exercising. Acknowledging that she went through a slump and bravely getting back on her feet reflects a shift in mindset that is often more valuable than dieting alone. Her recovery in terms of mental health was undoubtedly the strongest foundation for her successful loss of more than 10 kg.

Giving up malatang was key to her success

Controlling your diet is always the hardest hurdle in losing weight. Sharing her weight-loss journey, Lee Su-hyun specifically mentioned having to painfully give up her favorite malatang and tteokbokki. Though delicious, these dishes are calorie bombs loaded with refined carbohydrates, sodium, and fat, making them a definite no-go for anyone hoping to shape their body.

Giving up these intensely flavored foods must have been difficult at first, yet it was a necessary step in resetting her metabolism. Taste buds accustomed to bold flavors need time to adjust to the lighter taste of whole foods. By strictly controlling calorie intake and replacing processed foods with protein-rich foods and plenty of dietary fiber, the body will naturally give the most direct response. Looking at her lighter physique now, giving up those late-night snacks was clearly well worth it.

Brother Lee Chan-hyuk’s Spartan training was the perfect ally

A key figure behind this weight-loss plan was her brother Lee Chan-hyuk, whom she lives with. The two shared amusing stories from their life together on a tvN program. Lee Chan-hyuk became an extremely strict personal trainer, requiring his sister to wake up early to exercise, manage herself, and stick to a regular routine of going to bed at 10 p.m.

Being asked every day whether she’d done cardio, run on the treadmill, or sent in her food log may sound suffocating, yet this high-pressure supervision was the best cure for laziness. Lee Su-hyun joked that her brother never stopped nagging her, to the point that all she could see was his mouth moving. This seemingly merciless physical training also offered tremendous mental benefits. Having someone by your side to keep pushing and supporting you is key to getting through a weight-loss plateau.

Along with a regular schedule, her high-intensity workout routine was another major highlight. Lee Su-hyun often shares posts of herself drenched in sweat after running on social media. Jogging is an excellent full-body cardio exercise: maintain a moderate-to-high intensity for more than 30 minutes, and the brain releases endorphins, producing the so-called runner’s high. This can have remarkable effects on easing depression and relieving stress.

Even more admirable, she has set her sights on competing in a boxing match and recently posted a D-1 countdown update. Boxing is an explosive workout that combines aerobic and anaerobic exercise, burning an average of 400 to 700 calories per hour. Sweating it out and punching a heavy bag can quickly burn fat, define muscle, and let you punch away the negative emotions that build up in daily life. It’s a highly recommended exercise option for people under modern-day pressures.

What moves people most about Lee Su-hyun’s transformation isn’t how many kilograms she lost, but the confidence she radiates. Losing weight should never be about conforming to society’s beauty standards; it should be about finding your energetic, healthy, happy self again. Through her actions, she has shown that rather than relying on quick-acting remedies that can harm your health, it’s better to steadily adjust your diet and build an exercise habit.

Her family’s support and encouragement also played an extremely important role in this process. If you’re currently struggling with your body or a sense of being in a slump, try finding a workout partner who’s strict yet loving. Keep each other accountable and sweat together, turning the painful weight-loss process into fuel for growing together. That’s the ultimate secret to maintaining a healthy physique over the long term.
