1)Don't skip meals. Try to stick to your usual mealtimes each day. Skipping meals or fasting can increase the risk of gallstones. 2)Lose weight slowly. If you need to lose weight, go slow. Aim to lose 0.5 to 1 kilogram a week. 3)Try to maintain a healthy weight. Obesity and being overweight increase the risk of gallstones. Work to achieve a healthy weight by reducing the number of calories you eat and increasing the amount of physical activity you get. Once you achieve a healthy weight, work to maintain that weight by continuing your healthy diet and continuing to exercise. Hope that helps
