This study aimed to assess the impact of implementing the low Fermentable Oligo-, Di- and Monosaccharides, And Polyols (FODMAP) diet, through an online educational service platform, on the quality of life of patients living with irritable bowel syndrome (IBS). A prospective single-group intervention pilot study involving patients with IBS from two hospitals was conducted. Participants followed the low FODMAP diet using a web-based platform for 6 months. The IBS quality of life questionnaire (IBS-QoL), the IBS symptom severity scoring system (IBS-SSS) and the State-Trait Anxiety Inventory Form Y (STAI) were completed at baseline, after the restriction phase and after reintroduction phase.

Participants were invited to follow the online low-FODMAP diet offered by SOSCuisine®, characterized by three specific features. First, participants received customized weekly low-FODMAP menus based on the Monash University protocol. Second, a virtual assistant accompanied participants from the beginning to the end of the diet implementation, providing personalized recommendations tailored to individual's preferences and intensity of symptoms. For the reintroduction phase, the assistant guided individuals through the process of testing specific FODMAP subgroups, offering food suggestions based on individual preferences, and portion sizes. The last feature of the platform was the access to a peer support group on Facebook©, designed to foster communication among participants. This group allowed individuals to ask questions and receive valid answers, as the group was moderated by a FODMAP-specialized registered dietitian.

IBS-related quality of life
The primary outcome was the change in QoL from baseline to the end of study, assessed by the validated IBS-QoL questionnaire. This questionnaire assesses 8 domains, namely dysphoria, interference with activity, body image, health worry, food avoidance, social reaction, sexual concerns and relationships, from which a computed score is drawn. This score, ranging from 0 to 100, was developed to assess the self-reported QoL in IBS, a higher score indicating a better QoL.
Time frame: From enrollment to the end of intervention at 6 months.
Severity of IBS symptoms
Secondary outcomes included changes in severity of IBS symptoms, measured by the validated IBS-Severity Scoring System (IBS-SSS). This questionnaire evaluates 5 specific domains within the last ten days: abdominal pain severity, abdominal pain duration, abdominal distension, bowel habits dissatisfaction and interference with life. A composite score is calculated and varies from 0 to 500. Depending on the score, the severity can be classified in 4 categories: absence of symptoms severity or remission (score \< 75), mild (score 75-174), moderate (score 175-299), and severe (score ≥ 300).
Time frame: From enrollment to the end of intervention at 6 months.
State and trait anxiety
Anxiety was evaluated by the French-Canadian adaptation of the State-Trait Anxiety Inventory Form Y (STAI), which specifically assesses state anxiety (STAI-S), the subjective and transient emotional state of anxiety, and trait anxiety (STAI-T), a more stable predisposition to anxiety. The STAI-S score can be classified in 5 categories: very low state anxiety (score \< 36), low (score 36-45), moderate (score 46-55), high (score 56-65), and very high (score \> 65). For the STAI-T score, a score inferior to 40 commonly indicates low trait anxiety while a score of 40 or more indicates high trait anxiety.
Time frame: From enrollement to the end of intervention at 6 months.
