The safest way to lose weight is to lose between 0.5g to 1kg per week, this has been proven to maintain your weight-loss. Research has also shown that very rapid weight loss can increase the risk for developing gallstones.

Obesity is a strong risk factor for the development of gallstones, especially among women. Studies have shown that the risk for developing gallstones may triple in women who have a BMI greater than 32 and seven times higher in women with a BMI above 45.

Being obese may produce high levels of cholesterol which leads to the production of bile containing more cholesterol than it can dissolve. This process can lead to the formation of gallstones. People who are obese may also have large gallbladders that do not empty normally or completely, thereby increasing your risk. Abdominal obesity is also a risk factor for developing gallstones.

But recent studies have also shown that people who lose more than 1.5kg per week may have a greater risk for developing gallstones. Following a diet too low in fat or skipping meals may also help to form gallstones. Weight fluctuations may also increase the risk for gallstones. People who gain and lose more than 4.5kg due to weight cycling have a higher risk for gallstones than a person who loses weight and maintains their weight loss.
