This paper is a systematic review of the efficacy of strategies to prevent gallbladder stones in adults as they lose weight. The analysis included 13 trials, comprising 1,837 participants undergoing weight loss through dieting (eight trials) or bariatric surgery (five trials).
Regarding high fat and low fat diets, the study found that diets high in fat content reduced gallstones by 91%, compared with those with low fat content.
