Foods to Avoid on GLP-1 (Ozempic, Wegovy, Mounjaro)
Many people on GLP-1 medication find some foods harder to tolerate, especially rich or fried dishes, big portions, fizzy drinks, alcohol and very sweet foods. None is off limits for everyone, and tolerance varies. The table below shows what makes each one harder and a gentler swap you can cook, linked to a recipe.
Foods many people find harder, and a gentler swap
Read across: the food, what makes it harder, and a recipe to try instead.
| Food type | What makes it harder | A gentler swap |
|---|---|---|
| Rich, fried or creamy dishes | Richness and fat. Higher-fat food tends to leave the stomach more slowly, and these medicines already slow it. | Herb Barramundi with Rice & Zucchini |
| Restaurant-size portions | Portion size. A full plate can feel like too much when you fill up after a few bites. | Herbed Cod and Soft Brown Rice Pasta Bowl |
| Fizzy drinks | Carbonation. The gas lands in a stomach that already empties slowly. | Creamy Vanilla Yogurt Protein Sip Smoothie |
| Alcohol | Alcohol itself. It can add to dehydration, which is already a worry when you eat and drink less. | Watermelon-Mint Protein Slush |
| Very sweet foods | Sweetness. They are easy to fill up on, which leaves less room for protein. | Frozen Greek Yoghurt Berry Bark |
It's personal
Some people on GLP-1 medication eat most of these foods without a problem. Others find them hard all the time. The advisory behind this guide asks for advice that follows individual tolerance, and that's the right way to read the table.
If a food is on the list, you can still try it. Start with a smaller portion, or have it when your appetite is strong, and see how it sits. For the full picture of what tends to go down well, see our GLP-1 food list.
When one problem keeps coming back
These guides group gentler recipes by what you're dealing with: nausea, bloating, constipation and low appetite.
