Adherence
Dietary modifications, specifically reducing meal size and avoiding high-fat or spicy foods, are effective non-pharmacological interventions for managing mild gastrointestinal side effects during GLP-1RA treatment.
To avoid stomach upset from GLP-1s, eat smaller portions, stop when you feel full, and avoid greasy or spicy foods, especially when starting. Drink plenty of water and increase fiber if you are constipated.
ModerateSupportsMEDIUM confidence
Patients should be advised on potential management approaches that may be effective in mitigating side effects, including reducing meal size, mindfulness to stop eating once full, avoiding eating when not hungry, avoiding high-fat or spicy food (particularly during the initial dose-escalation period)...
Why this rating
Based on clinical experience and expert consensus rather than specific RCTs on dietary interventions for GLP-1 side effects.
