When K-pop star Jang Wonyoung (IVE) shared her morning ritual of drinking extra virgin olive oil mixed with fresh lemon juice on an empty stomach, it ignited a global beauty craze. Fans rushed to replicate the so‑called “Olle Shot,” seeking the radiant skin the singer credits to the regimen. But soon, social media platforms filled with complaints: instead of clear complexions, many reported painful breakouts, tiny bumps, and stubborn mouth ulcers. Concerned by the backlash, U Food spoke with Natural Plus chief nutritionist Kennie Siu, who warns that this extreme diet fix can backfire for a significant number of people.
The Olle Shot Phenomenon
Wonyoung’s method involves swallowing a dose of extra‑virgin olive oil and fresh lemon juice first thing in the morning. In theory, both ingredients are rich in antioxidants—olive oil contains polyphenols, while lemon juice is packed with vitamin C, which boosts collagen production. Early adopters reported smoother skin and a perceived glow, fueling the trend’s viral spread.
Why the Backlash?
However, thousands of users later shared “horror stories”: inflamed acne across the face and scalp, intense itching, and the sudden appearance of painful mouth ulcers (known locally as “flying sores”). Nutritionist Kennie Siu identifies the root cause as an acute inflammatory or allergic reaction triggered by the method itself. “Slugging pure fat and strong citric acid on an empty stomach creates extreme stress on the digestive system,” she explains. “For anyone with a sensitive gut, that stress can spike cortisol levels, directly provoking breakouts.”
Pure lemon juice, she adds, is highly acidic. Taken undiluted, it strips the mouth’s natural protective barrier, turning minor abrasions into agonizing ulcers.
Three Groups at High Risk
Kennie emphasizes that certain individuals are especially vulnerable and must avoid the Olle Shot entirely:
- People with GERD (gastroesophageal reflux disease): The combination of high acidity and high fat relaxes the esophageal sphincter, worsening heartburn and acid reflux.
- Those with gallbladder issues or insufficient bile secretion: A sudden influx of pure fat can trigger painful gallbladder contractions, potentially aggravating gallstones or causing biliary colic.
- Long‑term medication users: Fat slows gastric emptying, while high‑dose lemon juice may interfere with liver metabolism of drugs such as statins and antihistamines.
According to Kennie, even the highest‑quality “extra virgin” oil doesn’t solve the core problem—the risky delivery method itself.
A Gentler, Effective Antioxidant Routine
For those who still want the nutritional benefits without the side effects, Kennie proposes a science‑backed alternative: start the day with a large glass of warm water infused with two slices of lemon. Then, during breakfast, drizzle one tablespoon of extra‑virgin olive oil over scrambled eggs or whole‑grain toast. This way, the antioxidants are absorbed with food, minimizing digestive shock and protecting oral tissues.
“Skin health is never about a single ingredient,” Kennie stresses. “If you suspect any diet change is causing adverse reactions, stop immediately and consult a professional.”
The Takeaway
The Olle Shot frenzy serves as a cautionary tale about the dangers of blindly following celebrity health fads. While olive oil and lemon are nutritious, consuming them in extreme ways can trigger inflammation, digestive distress, and oral damage. Nutrition experts urge a balanced, personalized approach—and remind us that sustainable wellness rarely comes from a one‑size‑fits‑all shot.
