If a GLP-1 medication has reduced your appetite, focus on making smaller amounts of food count: prioritize nutrient-dense foods, include protein regularly, stay hydrated, and choose portions and textures you tolerate well. Nutrition needs vary, especially if nausea, vomiting, constipation, or very low intake is present, so persistent problems should be discussed with your prescriber or a registered dietitian.

Medical note: This article is general education, not medical advice, and not a substitute for individualized guidance from your prescriber or registered dietitian.
GLP-1-based therapies can reduce appetite, and some people also experience gastrointestinal side effects. The 2025 multi-society nutrition advisory from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association, and The Obesity Society emphasizes nutrition quality, adequate intake, hydration, and individualized support during treatment. How much any of this affects you is personal — two people on the same medication can have very different experiences.
Think in priorities rather than rules. When you can only eat a little, what goes in first matters more than what you leave out.
1. Protein-containing foods. Eggs; Greek yogurt or cottage cheese if tolerated; chicken, turkey, fish, or lean beef; tofu and soy foods; beans and lentils if tolerated; protein-forward prepared meals. Protein needs vary with body size, age, health status, kidney function, activity, and treatment plan — there is no universal gram target that is right for everyone.
2. Fruits and vegetables you tolerate. Smaller servings, cooked vegetables, soups, or softer textures may be easier for some people. Tolerance is individual, so pay attention to what actually works for you.
3. Fluids. Hydration matters, especially when intake is lower or GI symptoms show up. If you have heart, kidney, or other fluid-restricted conditions, follow your clinician's instructions instead of a general rule.
4. Nutrient-dense additions when intake is very low. Foods that carry more nutrition per bite can help you get enough without a large volume of food. What that looks like is best decided with your care team.
None of this includes changing your medication timing or dose. That conversation belongs with your prescriber.
If nausea, vomiting, abdominal pain, severe constipation, an inability to keep fluids down, or other significant symptoms are making it hard to eat or drink, contact your prescribing clinician. Meal strategy is not the right tool for a symptom that needs medical attention.
Prepared meals can help simply because the food is already cooked, portioned, and labeled — there is no cooking decision standing between you and eating something. Depending on your needs and safe storage handling, one prepared entrée may cover more than one eating occasion.
SmashMeals offers a rotating menu from a dedicated gluten-free kitchen, with nutrition information on menu items and protein-forward options. There is no "GLP-1 meal plan" here — you choose meals based on your own treatment plan and tolerance. Our GLP-1 hub covers the same ground in more depth.
