Boiled-Food Diets Risk Gallbladder Damage, Stones
Extremely low-fat diets centered on boiled foods can damage the gallbladder and increase gallstone risk by preventing normal bile release, warns Dr. Zhao Weirou. Healthy weight loss requires balanced nutrition with moderate amounts of healt
Cutting Fat Through Boiled Food Diets Risks Gallbladder Problems, Warns Specialist
Many people pursuing weight loss have turned to restrictive diets centered on simple foods like boiled chicken breast, steamed vegetables, and egg whites—with no oil or sauces added. However, this approach is raising concerns among gastroenterologists and liver specialists. Dr. Zhao Weirou notes that while people may feel they are eating "clean," such extremely low-fat regimens can prevent the gallbladder from functioning or contracting normally over extended periods, increasing the risk of bile sludge and gallstone formation.
Dr. Zhao explains a common misconception about fat reduction: the gallbladder is not a useless organ but rather stores bile. When dietary fat is consumed, the body signals the gallbladder to contract and release bile to aid digestion. The gallbladder does not need to avoid fat entirely; instead, it needs to contract and release bile regularly. Prolonged very-low-fat dieting combined with severe calorie restriction reduces gallbladder contractions, allowing bile to accumulate internally. Rapid weight loss over a short period can alter bile composition and further increase the risk of sludge and stones.
Not an Excuse to Eat Fried Foods
Dr. Zhao emphasizes that this advice does not mean weight-loss dieters should switch to fried chicken or greasy foods. The key to healthy fat reduction is not eliminating fat to zero but choosing appropriate fats in proper portions. Sustainable long-term weight loss should not consist solely of dry boiled chicken breast. A balanced lunch should include vegetables, protein, natural carbohydrates, and small amounts of healthy fat—for example, chicken with vegetables and sweet potato drizzled with a little olive oil, or salmon with steamed vegetables and brown rice. Tofu, eggs, and vegetables supplemented with small portions of nuts is another option.
Five Warning Signs During Weight Loss That Warrant Gallbladder Screening
Dr. Zhao warns that if these symptoms appear during weight loss, do not assume they are only stomach or intestinal issues; consider getting a gallbladder ultrasound:
• Pain or tightness in the upper right abdomen • Discomfort or worsening symptoms after eating fatty food • Nausea and bloating • Sharp pain radiating to the right shoulder or back • Rapid weight loss over a short period
Finally, Dr. Zhao stresses that boiled or low-fat foods are not inherently harmful. What may damage health is prolonged consumption of very-low-fat foods, excessive calorie restriction, and rapid weight loss. Adequate fat intake stimulates normal gallbladder contractions and bile release. Healthy fat reduction should accompany normal gallbladder and digestive system function, not eliminate dietary fat entirely.
