A 30-year-old woman in mainland China who cut out breakfast to shed weight quickly ended up in the emergency room with acute cholecystitis, after developing four gallstones that required surgical removal of her gallbladder. Her dramatic 13.5-kilogram loss over three months—achieved by skipping breakfast and eating only chicken breast and salad—triggered a painful condition that doctors say is three to five times more likely in people who lose weight too fast.
The Case
The woman, hoping to fit into her summer wardrobe, adopted an extreme diet: no breakfast, and only lean protein and vegetables for lunch and dinner. Within three months, she dropped 13.5 kg (about 30 pounds). But soon after, she began experiencing intermittent abdominal discomfort. She ignored it until one day, severe pain sent her to the emergency room. An ultrasound revealed four gallstones, the largest measuring 1.2 cm, lodged in the neck of her gallbladder. The blockage caused acute cholecystitis, an inflammation that ultimately required the organ’s removal.
Why Rapid Weight Loss Triggers Gallstones
Physicians warn that crash dieting significantly raises the risk of gallstone formation. During rapid weight loss, the body breaks down fat stores quickly, prompting the liver to release extra cholesterol into bile. When bile becomes overloaded with cholesterol, the gallbladder’s ability to contract and empty properly is impaired. Bile stagnates, cholesterol crystallizes, and stones form.
“The incidence of gallstones in people undergoing rapid weight loss is three to five times higher than in the general population,” explained a local doctor quoted in Chinese media. The woman’s rate of loss—roughly 4.5 kg per month—far exceeded the healthy benchmark of 2 to 4 kg per month, according to Dr. Fan Quanshan, a gastroenterologist at Changhua Christian Hospital in Taiwan.
Dr. Fan cautioned that individuals with a family history of gallbladder disease should avoid extreme fasting methods such as the 168 regimen. “The key is to maintain balanced meals, ensure adequate fiber intake, and simply reduce calories—not skip entire meals,” he said.
Risk Factors Beyond Skipping Breakfast
While skipping breakfast is a known trigger, other lifestyle habits also contribute to gallstone risk. Sedentary behavior slows metabolism and reduces gallbladder contraction frequency, leading to bile stagnation. Eating late at night forces the gallbladder to work when it should be resting, disrupting bile flow. Even popular festive foods like hot pot, lamb brisket, and cured meat rice can provoke an acute attack if a stone is already blocking the bile duct, as the sudden intake of fatty foods stimulates a surge in bile production.
Dietary Tips to Prevent Gallstones
To reduce the risk of gallstones, experts recommend a fiber-rich diet and regular meal timing. Always eat breakfast, incorporate whole foods, and avoid high-cholesterol, high-fat, and high-calorie meals. Daily exercise and maintaining a healthy weight are also essential.
Taiwanese dietitian Gao Minmin shared seven actionable dietary adjustments:
- Choose simple cooking methods: Steam or boil instead of frying or deep-frying.
- Eat whole foods: Replace refined grains with brown rice, oats, sweet potatoes, and legumes.
- Increase dietary fiber: Fiber helps bind bile acids and promotes their excretion.
- Avoid overeating: Large meals can cause vigorous gallbladder contractions that may dislodge stones.
- Limit sugary foods: Excess sugar and fat increase digestive burden.
- Ignore folk remedies: Herbal treatments cannot dissolve existing gallstones; once formed, they are irreversible.
- Don’t space meals too far apart: Long gaps between meals allow bile to accumulate, encouraging stone formation.
Broader Implications
This case underscores a critical public health message: extreme dieting, though tempting for quick results, can lead to serious, irreversible complications. Health professionals urge anyone considering weight loss to aim for a steady, sustainable pace—no more than 2 to 4 kg per month—and to prioritize nutritional balance over speed. For those already experiencing abdominal pain or gallbladder issues, consulting a gastroenterologist before adopting any new diet is essential.
