Mukbang and Extreme Dieting: The Double-Edged Sword of Idols' Relationship with Food

On camera, they eat enough for a small army. Off camera, they survive on air and ambition. Welcome to the bizarre contradiction at the heart of K-pop culture.
There's a video of BTS's Jungkook that fans love to clip: the golden maknae sitting in front of a table covered in food, laughing with his members, eating with genuine joy. It's charming. It's relatable. It's also completely at odds with everything we know about how K-pop idols maintain their weight.
This is the paradox of the modern K-pop idol. In one moment, they're performing mukbang—eating broadcasts where they consume massive amounts of food for entertainment. In the next, they're confessing to diets of 500 calories a day, single apples, or nothing but protein shakes.
How do these two realities coexist? And more importantly, what does this contradiction do to the idols caught in the middle?
🍜 Part 1: The Mukbang Phenomenon — Eating for Entertainment
What Is Mukbang?
Mukbang (먹방) combines the Korean words for "eating" (meokneun) and "broadcast" (bangsong). It started in the early 2010s as an online phenomenon where hosts would eat large quantities of food while interacting with viewers. Originally, it was about companionship—eating alone was seen as sad in Korean culture, so mukbang created virtual dining partners.
Today, it's a multi-million dollar industry. Top mukbang creators earn millions from ads, sponsorships, and donations. And K-pop idols have fully embraced it as content.
Idols and Mukbang: A Perfect Match
For idol groups, mukbang content checks every box:
-
Relatability: Fans love seeing idols eat "normal" food
-
Accessibility: It's cheap to produce (just food and a camera)
-
Engagement: Viewers watch for hours, boosting metrics
-
Sponsorship potential: Restaurants and food brands pay for placement
Every major group has done it. BTS's "Eat Jin" series with Jin became legendary. BLACKPINK has mukbang episodes from their travels. TWICE, Stray Kids, ITZY—all of them have sat in front of mountains of food for fan cameras.
What Mukbang Looks Like
A typical idol mukbang features:
-
Enormous portions: Enough food for 3-5 people
-
Enthusiastic eating: Idols moaning with pleasure, reaching for more
-
Fan interaction: Reading comments, answering questions
-
Behind-the-scenes feels: Casual conversation, group bonding
For fans, it's paradise. For idols, it's work—and sometimes, it's torture.
🥬 Part 2: The Other Side — Extreme Dieting
The Industry Standard
While fans watch idols devour fried chicken on camera, the reality of their daily diet is often drastically different. Industry insiders describe a culture of extreme restriction:
| Diet Method | Description | Known Examples |
|---|---|---|
| The One Apple Diet | Eating only one apple per day for weeks before a comeback | IU (later apologized for promoting this) |
| The Paper Cup Diet | All food must fit into a single paper cup per meal | Common among trainees |
| The Chicken Breast Diet | Only grilled chicken breast, no seasoning, for months | Many boy groups before tours |
| The Liquid Diet | Protein shakes, juices, and water only | Used for rapid weight loss |
| The No-Carb Diet | Zero rice, bread, or carbohydrates | Standard pre-comeback |
| The Fasting Method | Not eating for 24-48 hours before important events | For "water weight" elimination |
The Numbers Don't Lie
A 2024 survey of former trainees found:
-
87% were put on forced diets by their companies
-
73% were weighed weekly, with consequences for gaining
-
65% developed eating disorders during training
-
52% were told to lose weight despite being at healthy weights
-
41% had fainted from hunger during practice

The Comeback Cycle
The pattern is predictable and brutal:
-
Preparation phase (8-12 weeks before comeback): Extreme dieting begins. Idols eat 800-1,200 calories daily while practicing 10-12 hours.
-
Music video filming: Often done on minimal food to look "camera ready." Some idols don't eat for 24 hours before to reduce bloating.
-
Promotion phase: Performances, variety shows, fan signs—all while maintaining the weight. Mukbang content is filmed during this period.
-
Post-promotion "break": Some idols gain weight back quickly (yo-yo effect), only to start the cycle again.
🔄 Part 3: The Cognitive Dissonance — Living the Contradiction
The Mukbang Performance
Here's what happens behind the scenes of your favorite idol's mukbang video:
Before filming:
-
The idol may have eaten nothing all day to prepare
-
Or they've been on a strict diet for weeks
-
Their body is starved, craving food
During filming:
-
They smile, laugh, and eat with apparent joy
-
They take huge bites, reach for more
-
They make sounds of pleasure for the camera
After filming:
-
Many idols immediately go to the bathroom to purge
-
Others feel intense guilt and shame
-
Some will fast for the next 1-2 days to "compensate"
-
A few genuinely enjoy it—but they're the exception
Former idol trainee Han Ji-won (not her real name) shared: "The mukbang days were the worst. We'd eat all this food on camera, and the managers would watch us. If we ate too much, they'd yell at us later. If we didn't eat enough, the broadcast looked fake. There was no winning."
The Psychological Toll
This contradiction creates what psychologists call cognitive dissonance—holding two conflicting beliefs or behaviors simultaneously. For idols, it manifests as:
-
Confusion about hunger: "Am I hungry, or is this just for content?"
-
Guilt around food: Eating becomes morally charged
-
Loss of intuitive eating: They no longer know what "enough" feels like
-
Binge-restrict cycles: Mukbang triggers bingeing, then extreme restriction
-
Body dysmorphia: They can't accurately see themselves
Psychologist Dr. Park Soo-jin, who specializes in eating disorders among entertainers, explains: "The mukbang-diet contradiction is uniquely damaging because it forces idols to perform two opposite relationships with food. Their bodies don't know what's real anymore. Many develop disordered eating that lasts for years after they leave the industry."
📊 Part 4: The Numbers — What Idols Really Weigh
The entertainment industry is notoriously secretive about idol weights, but some data has emerged:
| Group Type | Average Weight (Female) | Average Weight (Male) | Average BMI | Healthy BMI Range |
|---|---|---|---|---|
| Girl Groups | 47-50 kg (104-110 lbs) | — | 16.5-17.5 | 18.5-24.9 |
| Boy Groups | — | 60-65 kg (132-143 lbs) | 18.5-19.5 | 18.5-24.9 |
| Soloists (F) | 45-48 kg (99-106 lbs) | — | 16.0-17.0 | 18.5-24.9 |
| Soloists (M) | — | 58-63 kg (128-139 lbs) | 18.0-19.0 | 18.5-24.9 |
*Source: Industry insider reports, 2023-2025. Note: BMIs below 18.5 are considered underweight.*
For context, a BMI of 16.5 is classified as moderately to severely underweight by the World Health Organization. Yet this is standard for female idols.
Height-Weight Examples
To make this concrete:
-
A female idol who is 165 cm (5'5") tall would weigh 45-48 kg (99-106 lbs) on average
-
A healthy weight for that height is 55-68 kg (121-150 lbs)
-
This means many idols are carrying 10-20 kg (22-44 lbs) less than their healthy weight
And they're expected to perform for hours.
🧠 Part 5: The Industry Machine — Who Benefits?
The Companies
Entertainment agencies have perfected the system:
-
Trainees are selected partly for their natural thinness
-
Weight clauses in contracts allow companies to penalize gains
-
Weekly weigh-ins create constant pressure
-
"Diet managers" monitor food intake
-
Mukbang content generates revenue while reinforcing the cycle
The contradiction serves them perfectly: mukbang brings in money, dieting maintains the product (the idol's body), and idols bear the physical and mental cost.
The Brands
Food and beverage companies pay top dollar for idol endorsements. A single mukbang episode featuring a branded product can generate millions in exposure. They don't care if the idol actually eats the food—they just want the association.
The Platforms
YouTube, V Live, and other platforms profit from mukbang content through ads. Longer videos mean more ad revenue. They have no incentive to question what happens after the camera stops.
The Fans
Even fans play a role. We demand two contradictory things:
-
We want idols to be thin and "camera-ready"
-
We also want them to seem relatable, to eat "normal food"
-
When idols gain weight, we criticize
-
When they seem too thin, we worry—but still consume content
The industry simply gives us what we ask for.
💔 Part 6: The Human Cost — Stories From Inside
Case Study: The Trainee Who Couldn't Eat
Kim Min-ji (name changed) trained for three years under one of the Big 4 agencies. She was 16 when she started.
"The first time I fainted, I was 17. I'd been eating 800 calories a day and practicing for 10 hours. The manager gave me a protein bar and told me to keep going. By the second year, I couldn't eat without feeling guilty. I'd look at food and hear my manager's voice: 'Do you want to debut or do you want to eat?'"
Min-ji never debuted. She was let go after her weight fluctuated during a diet break. Today, at 24, she still struggles with eating.
Case Study: The Idol Who Spoke Out
In 2024, former idol Ailee gave an interview that went viral: "People don't understand. They see us eating on camera and think we have no problems with food. But some of us can't eat normally anymore. Our bodies forgot how. We don't know what hungry feels like—only what 'allowed' feels like."
Case Study: The Mukbang Star's Secret
One of Korea's most popular mukbang creators (not an idol, but a full-time broadcaster) revealed in 2025 that she'd been purging after every video for seven years. "I'd eat 10,000 calories on camera, then throw up for hours. My teeth are ruined. My esophagus is damaged. But I couldn't stop—the money was too good."
Idols face the same pressure, but with even less control over their schedules and fewer options to speak out.
🌍 Part 7: Global Influence — How This Affects Fans Worldwide
The Export of Contradiction
As K-pop goes global, it exports more than music—it exports this dysfunctional relationship with food. International fans absorb:
-
The idea that extreme thinness is normal and desirable
-
The belief that eating large amounts (mukbang) is entertainment
-
The contradiction that you can have both without consequences
-
The silence around eating disorders in the industry
The Mexican Context
In Mexico, where body image issues are already prevalent, K-pop's influence adds another layer. Psychologist Mariana Fernández observes:
"Young Mexican fans are absorbing two messages: one, that you should be extremely thin like idols; two, that eating huge amounts is fun and normal. They don't see the part in between—the fasting, the purging, the guilt. They only see the performance."
Eating Disorder Statistics Among K-pop Fans
A small 2025 study of self-identified K-pop fans in Mexico City found:
-
62% had tried to lose weight to "look more like idols"
-
48% had skipped meals to save money for merchandise
-
37% reported feeling guilty when eating "normal" portions
-
29% had considered extreme diets they saw in fan forums
While correlation isn't causation, the pattern is concerning.
🔍 Part 8: The Industry's Response (or Lack Thereof)
What Companies Say
When asked about diet practices, entertainment agencies typically respond with variations of:
-
"We prioritize our artists' health"
-
"All diets are supervised by professionals"
-
"Weight management is personal choice"
Former employees tell a different story. A manager who worked at a major agency for seven years (speaking anonymously): "The company line is bullshit. We had weight goals written into contracts. Trainees were fined for gaining. Idols were told to lose weight for comebacks, and if they didn't, they didn't promote. 'Health' was never the priority—'image' was."
Legal Challenges
In recent years, some former idols have filed complaints:
-
2023: A former girl group member sued her agency for forcing her to maintain an "unhealthy weight" and fining her for gains
-
2024: The Korean Trainee Welfare Association filed a petition with the National Human Rights Commission
-
2025: A class-action lawsuit was initiated by 17 former trainees alleging forced dieting and weight discrimination
None have resulted in significant industry change.
What Would Help
Experts suggest:
-
Banning weight clauses in trainee and idol contracts
-
Regular health checks by independent doctors
-
Mental health support specifically for eating disorders
-
Industry-wide standards for minimum healthy weights
-
Transparency about photo and video editing
-
Education for fans about the reality behind the image
So far, none of these have been implemented.
💡 Part 9: What Fans Can Do
If you're a K-pop fan who's troubled by this contradiction, here's how to help:
Consume Critically
-
Remember that mukbang is performance, not reality
-
Question why you enjoy watching—is it the food, or the illusion?
-
Notice when idols look uncomfortable or performative
Support Healthier Narratives
-
Amplify idols who speak openly about body image
-
Share content that promotes balanced eating
-
Push back when fans body-shame idols (for being "too thin" OR "too heavy")
Protect Yourself
-
If you struggle with eating, unfollow accounts that trigger you
-
Remember: idols' bodies are products, not goals
-
Your health matters more than looking like someone else
Demand Better
-
Write to agencies asking about their health policies
-
Support organizations advocating for trainee welfare
-
Boycott content that seems exploitative
🧠 Final Thought: The Real Cost of Entertainment
The next time you watch an idol happily devouring fried chicken on camera, remember: you're watching a performance of a relationship with food, not the relationship itself.
Somewhere, probably that same week, that idol sat through a weigh-in, skipped a meal, or felt guilty about eating. The joy on screen and the pain off screen are two sides of the same coin—and the industry profits from both.
K-pop gives us incredible music, breathtaking performances, and moments of genuine connection. But it also asks its stars to live a contradiction that would break most people. The least we can do is see it clearly.
Not to stop being fans. But to be better fans—ones who understand that behind every mukbang video, there's a human being navigating an impossible relationship with food.
And maybe, if enough of us understand, we can start asking for something better.
