This study aimed to explore whether time-restricted eating (TRE) could alleviate symptoms in patients with IBS. Methods: This single-group, pre\u2013post pilot study included participants with IBS who followed an 8-week time-restricted eating protocol, defined as a daily 16 h fasting period and an 8 h eating window (16:8). Symptom changes were assessed using the validated IBS Symptom Severity Scale (IBS-SSS) at baseline and post-intervention. The study was retrospectively registered after completion of data collection. Results: A total of 134 patients were enrolled, of whom 97 completed the intervention. Participants demonstrated a mean reduction in the IBS-SSS score of \u2212100.2 (p &lt; 0.001). Subgroup analysis also demonstrated mean reductions in the IBS-SSS scores for participants with IBS-constipation (IBS-C) (\u2212125.2, p &lt; 0.001), IBS-diarrhea (IBS-D) (\u221276.0, p &lt; 0.005), and IBS-mixed (IBS-M) (\u221293.1, p &lt; 0.001). Additionally, the participants experienced improvements in both self-reported physical and mental health. Conclusions: These preliminary findings suggest that TRE may represent a promising behavioral strategy for IBS symptom management, warranting controlled trials.<\/jats:p>","DOI":"10.3390\/nu18050765","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T14:51:29Z","timestamp":1772117489000},"page":"765","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Time-Restricted Eating and Symptom Severity in Irritable Bowel Syndrome: Results from a Pilot Study"],"prefix":"10.3390","volume":"18","author":[{"given":"Maria Thompson","family":"Clausen","sequence":"first","affiliation":[{"name":"Department of Health and Exercise, School of Health Sciences, Kristiania University College of Applied Sciences, P.O.
