Key Points

• This research aims to identify psychological factors that predict the response to a low fermentable dietary intervention in individuals with irritable bowel syndrome.
• Conducted a prospective cohort study on individuals with irritable bowel syndrome (IBS)
• Measured baseline GSA anxiety and treatment expectations
• Analyzed their impact on response to a low fermentable diet (LFD)
• Lower baseline GSA anxiety predicts better response to LFD.
• Higher treatment expectations also predict improved dietary response across all phases.
