What to eat on Ozempic or another GLP-1
Small plates, protein first, go easy on fatty and greasy food, raise fiber slowly, and drink plenty of fluids. That’s the food side of a 2025 advisory from four US nutrition and obesity groups. This page is about food only. Dosing, side effects and anything about the medicine itself stay with your prescriber.
On a GLP-1 drug, the hard part flips. Before, it was eating less. Now a lot of people find they can barely finish a plate, and the risk is eating too little of the right things. The drugs slow down how fast food leaves the stomach, so you fill up sooner and stay full longer. In trials they lowered body weight by 5% to 18%.
The 2025 advisory, from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association and The Obesity Society, says “sufficient dietary protein should be a priority to help preserve muscle mass and bone density.”
We’d eat a smaller version of the same balanced plate, and eat the protein first. If you fill up halfway through, the part you already ate is the part that protects your muscle.
On a GLP-1 your stomach is a smaller suitcase. Pack the essentials first.
What does the advisory say about meals?
| Topic | The advisory’s words |
|---|---|
| Meal size | “eat a small breakfast and then additional small meals every 3–4 h while drinking adequate fluids” |
| Big meals | “Vomiting is more likely to occur with large meals” |
| Fat | “Avoidance of large or high-fat meals can be helpful” for diarrhea, and it suggests “avoiding fatty or high fiber foods during the first few days of treatment” |
| Fiber | “Gradual increase in foods with soluble and insoluble fiber, such as prunes or other dried fruits, can be helpful” for constipation |
| Food quality | “emphasize a diversity of nutrient-dense, minimally processed foods” |
| Help | “A registered dietitian nutritionist can help determine a dietary pattern that meets nutrition goals” |
What does a GLP-1 plate look like?
For a 200 pound person eating 1,400 calories over three meals, the plate window is 350 to 580 calories and the protein line is 35 g. On a GLP-1 a lot of plates come in under that window, and that’s fine as long as the protein holds, which is what the Muscle meter on our checker tracks.
| Plate | Calories | Protein |
|---|---|---|
| A palm of chicken, half a cup of lentils, two cups of spinach | 270 | 38 g |
| Three quarters of a palm of salmon, a cup of green beans, half a cup of quinoa | 290 | 23 g |
| A container of plain Greek yogurt and a cup of blueberries | 180 | 18 g |
The first plate is the model, with dense protein, beans and a vegetable and almost no added fat. The salmon plate is a good meal that comes in under the protein line, so a little more fish or half a cup of cottage cheese on the side would fix it.
If you have a lot of weight to lose, count your protein from your goal weight plus a fifth of what you weigh now. bodyfat.guide covers the drugs, the trials and what happens to muscle.
What to do
- Eat protein first at every meal: chicken, fish, eggs, Greek yogurt, cottage cheese, tofu or beans.
- Keep plates small and eat more often if you need to.
- Go easy on fried and greasy food, especially early on.
- Raise fiber slowly and drink fluids through the day.
- Call your prescriber early if side effects start, and right away if you can’t keep fluids down.
Eating much less also means fewer vitamins and minerals come in with the food. The advisory lists iron, calcium and vitamins D and B12 among the ones to watch, and says supplements such as vitamin D, calcium, B12 or a multivitamin can be considered, with levels checked during treatment. That’s a question for your prescriber. Can you get all your nutrients from food has what food covers first, and high protein low calorie meals has small plates that still hold 30 g of protein.
