Sun Dam-bi Lost 13kg Postpartum — But Should You Follow Her Plan?
South Korean singer and actress Sun Dam-bi recently made headlines for shedding 13 kilograms (about 28 pounds) just three months after giving birth. Her secret? Intermittent fasting — a method increasingly popular among celebrities and wellness enthusiasts alike.
According to Sun, she didn't resort to extreme dietary restrictions. Instead, she practiced a simple form of intermittent fasting: eating two meals a day and maintaining a fasting period from 6 p.m. until the following morning. She emphasized balance over restriction and flexibility over fads.

Intermittent Fasting: Smart Health Strategy or Risky Trend?
The Case For: A Balanced and Achievable Approach
Supporters of intermittent fasting point to scientific evidence suggesting it helps regulate insulin levels, enhances fat burning, and improves metabolic health. In Sun’s case, she found that a consistent routine of just two meals a day helped keep both her appetite and stress levels in check.
More importantly, this method suited her new role as a mother. Postpartum weight loss can be physically and emotionally taxing, and Sun’s story offers hope to women looking for sustainable solutions that don’t involve grueling workouts or complex diet plans. Her choice to eat what she enjoyed — in moderation — underlines a realistic standard many can relate to.
In an age where “bouncing back” after birth is often glorified, the fact that she prioritized health and balance, rather than trend-driven methods, makes her approach noteworthy.
The Case Against: Oversimplified and Potentially Harmful
Medical experts caution that intermittent fasting isn’t a one-size-fits-all solution — especially for new mothers. After childbirth, a woman’s body requires sufficient nutrients to recover, and longer fasting periods can disrupt this delicate process.
Particularly in cases where a mother is breastfeeding, skipping meals for long hours can lead to nutritional deficiencies. It may lower milk supply and impact both maternal and infant health.
Critics argue that Sun’s success might not translate to the average mother, who may not have access to tailored meal prep, domestic help, or the flexibility to focus exclusively on weight loss. They worry that promoting such methods could pressure other moms to emulate celebrity standards unfit for their lifestyles.
Further concern surrounds society’s increasing glamorization of post-baby slim-downs. When celebrities rapidly lose weight post-delivery, it can reinforce unrealistic beauty norms and lead to damaging behaviors in the general public.
Navigating Postpartum Diet Culture With Caution
While Sun Dam-bi’s story might inspire, health professionals emphasize that postpartum weight loss should never come at the cost of well-being. Every woman’s body responds differently — what works for one might harm another.
Fad diets or strict regimens might seem effective short-term, but their longer-term impacts on energy levels, mental health, and metabolism should not be ignored. New moms need support, not pressure to shrink into smaller sizes overnight.
The ideal approach respects individual needs — considering factors like lactation, hormone fluctuations (hormonal changes), mental health, and existing health conditions. Consulting with a doctor or nutritionist is always preferable to following open-ended internet advice or copying celebrity routines.
Understanding Public Sentiment — Inspiration or Pressure?
Many online users celebrated Sun Dam-bi’s discipline and transparency. “It’s great to hear she didn’t starve herself — just made sensible changes,” one fan commented. Others, however, urged caution. “Not every mom can afford to focus on two meals a day. Some of us are barely eating enough because of stress and fatigue,” another wrote.
Part of the divide stems from differing expectations: fans want to see positive progress, but also worry that such announcements can set unattainable standards. The internet age makes it easy to compare, but hard to contextualize.
In any case, Sun’s story ignites essential conversations around postpartum health, how we frame beauty, and what truly constructive support for mothers looks like.
Final Takeaway
Sun Dam-bi’s postpartum transformation showcases a method of weight loss that she found empowering and effective. But it’s crucial to remember she did it in a way that worked for her — within her body’s unique needs and lifestyle circumstances.
Rather than mimic her strategy blindly, new mothers should consider what balance means for them — not just in terms of diet, but in self-compassion, recovery time, and personal goals. Health, not haste, should lead the way.
