How do I handle big restaurant portions?

Order a starter as your main, split a dish, or ask for a takeaway box at the start and set half aside. Eating slowly and stopping when comfortably satisfied helps you avoid the fullness that triggers nausea.

Lead with a grilled or roasted protein (chicken, fish, eggs, tofu, beans) and add vegetables. Go easy on fried and very rich, creamy dishes, which are slower to digest and can worsen nausea.

Alcohol is a common nausea trigger on GLP-1 medications and adds calories with little nutrition. If you drink, keep it minimal and sip water alongside. Check with your provider.

Eating Out on a GLP-1: A Practical Guide

Published 29 May 2026Evidence-based · 3 sources

A smaller appetite doesn't mean you can't enjoy eating out. With a simple playbook, restaurants are easy to navigate — and the same habits that keep you comfortable also help you hit your nutrition goals.

The playbook

Order protein-first. Build the meal around a grilled or roasted protein — chicken, fish, seafood, eggs, tofu, or beans — then add vegetables. Protein keeps smaller portions satisfying and helps protect muscle while you lose weight.
Plan for the portion. Restaurant servings are large. Order a starter as your main, share a dish, or ask for a box up front and set half aside.
Eat slowly, stop when satisfied. Your stomach empties more slowly on a GLP-1, so overeating is the quickest route to feeling unwell.
Go easy on fried and very rich dishes. High-fat, greasy meals are slower to digest and a common nausea trigger.
Watch alcohol and fizzy drinks, which commonly aggravate GLP-1 stomach symptoms.
Sip water, but not so much during the meal that you fill up before you've had your protein.

Grilled chicken or fish with vegetables or salad
Egg-based brunch dishes (omelette, shakshuka)
Soups with beans, lentils, or chicken
Stir-fries — ask for less oil and extra protein
Greek or Mediterranean mezze: grilled meats, fish, yogurt, salads

Around dose-increase days

Nausea is more likely in the days after a dose increase. If you can, schedule big meals out for a week when you're feeling steady rather than right after a titration step.
