Question

which of the following is a risk factor for developing gallstones?
obesity
low fat diet
high fiber diet
regular exercise

Explanation:

Obesity is a known risk factor for gallstones. Excess body weight can lead to higher levels of cholesterol in bile, increasing the likelihood of gallstone formation. A low - fat diet, high - fiber diet, and regular exercise are generally associated with a lower risk of gallstones. A low - fat diet may reduce the secretion of bile, but it is not a risk factor. High - fiber diets can help with digestion and may prevent gallstones. Regular exercise can improve metabolism and reduce the risk of obesity - related conditions.

Answer:

Obesity.
