Adherence
Adhering to specific dietary modifications (smaller portions, low-fat, bland foods) and slow eating habits significantly reduces the frequency and severity of gastrointestinal adverse events (nausea, vomiting, diarrhea, constipation) in patients initiating GLP-1 receptor agonist therapy.
Start with small, bland, low-fat meals and eat slowly. Stop eating when you feel full, not stuffed. This simple behavioral change is the first line of defense against nausea and vomiting when starting GLP-1 medications.
GoodSupportsHIGH confidence
Patients have to learn that, although GI AEs may occur, these will be transient and of mild/moderate severity in the majority of cases and that following specific dietary recommendations will relieve symptoms (Table 2, Figures 1–3).
Why this rating
Based on expert consensus and real-world data, though not a randomized controlled trial of the diet itself.

- Extending the dose-escalation period or temporarily suspending dose increases when gastrointestinal adverse events occur improves tolerability and treatment persistence without compromising long-term efficacy.Good
- Pharmacological management of persistent nausea with domperidone (preferred over metoclopramide) or other anti-emetics/prokinetics is an effective strategy for managing GLP-1 RA-induced nausea when dietary and titration strategies fail.Good
