Although the formation of gallstones cannot be completely prevented, there are several ways to minimize the risk of development. They include:

• Eat a well-balanced diet. Eating a low-fat, high-fiber diet that includes fresh fruits, vegetables and whole grains is recommended. Patients should restrict the amount of animal fat, butter, margarine, mayonnaise and fried foods eaten. Patients should also avoid diets that involve eating very few calories (less than 800 per day).
  
  
• Maintain a healthy body weight.
  
  
• Exercise regularly.
  
  
• Avoid rapid weight loss.
