What to Eat on a GLP-1 Medication: A Symptom-by-Symptom Food Guide

GLP-1 medications such as semaglutide and tirzepatide slow the rate at which the stomach empties and change how hungry you feel. Because of that, the way you eat often needs to change too. Meals that sat fine before may now feel heavy, and it becomes easier to eat too little without noticing. This guide is organized by the most common issues people report, with food suggestions for each. It is educational and does not replace advice from your provider or a registered dietitian.

Ground rules that help almost everyone

• Eat smaller portions, and eat slowly
• Stop at the first sign of fullness
• Start the meal with your protein
• Sip fluids through the day
• Add fiber gradually, not all at once
• Keep fried and very rich foods occasional

If you feel nauseated

Nausea is most common when a dose is started or raised.

Try: plain, lower-fat foods in small amounts, such as toast, rice, crackers, bananas, applesauce, broth, plain yogurt, and baked chicken. Cold or room-temperature foods often have less smell and can be easier to manage. Ginger or peppermint tea suits some people.

Ease off: fried foods, creamy sauces, strong spices, and very sweet items.

Also: avoid lying down right after eating, and do not let your stomach get completely empty, since that can make nausea worse.

If you feel overly full or have reflux

Food stays in the stomach longer, so large meals can cause pressure, burping, or heartburn.

Try: five or six small meals in place of three large ones, and softer foods such as soups, eggs, and cooked vegetables.

Ease off: carbonated drinks, large portions, late-night eating, and high-fat meals.

Also: finish eating two to three hours before bed.

If you are constipated

Slower digestion combined with eating and drinking less commonly leads to constipation.

Try: more water, plus fiber from oats, chia seeds, beans, lentils, berries, pears, prunes, and cooked vegetables. Increase fiber a little at a time to avoid gas and bloating.

Also: daily walking helps. If constipation continues for several days, ask your provider before using laxatives regularly.

If you have diarrhea

Try: bland, lower-fiber foods for a day or two, such as rice, bananas, toast, and plain potatoes, with plenty of fluids. An oral rehydration drink can help replace what you lose.

Ease off: greasy foods, sugar alcohols found in many "sugar-free" products, and large amounts of caffeine.

If you have very little appetite

Eating too little is a real risk on these medications and can leave you short on protein, vitamins, and energy.

Try: setting regular meal times instead of waiting for hunger. Choose foods that pack nutrition into small portions: Greek yogurt, cottage cheese, eggs, fish, tofu, beans, nut butter, and smoothies made with milk or a protein source.

Also: if you are regularly unable to eat, or you are losing weight faster than your provider expected, report it. Your dose may need adjusting.

If you feel tired or lightheaded

This can come from not drinking enough, not eating enough, or, in people who take diabetes medication, low blood sugar.

Try: steady fluids, regular small meals that include protein and a whole grain, and a little salt in food if your provider has not restricted it.

Also: if you take insulin or a sulfonylurea, ask your provider how to recognize and treat low blood sugar.

Protein and muscle

When you eat less overall, protein is the nutrient most likely to fall short, and it matters for maintaining muscle. Include a source at every meal and snack. Good options are poultry, fish, eggs, dairy, tofu, beans, and lentils. Pair this with strength training twice a week. Ask your provider or a dietitian for a protein target suited to your size and health.

Alcohol

Alcohol can worsen nausea and reflux, adds to dehydration, and can affect blood sugar. Many people find they tolerate it less well on these medications. If you drink, keep it modest and have it with food.

A sample day

• Breakfast: Greek yogurt with berries and a spoonful of chia seeds
• Mid-morning: a hard-boiled egg or a small handful of nuts
• Lunch: grilled chicken or tofu with quinoa and cooked vegetables
• Afternoon: cottage cheese with sliced fruit, or hummus with cucumber
• Dinner: baked fish or lentils with a small sweet potato and steamed greens
• Through the day: water, with herbal tea if you like

Portions should be smaller than you may be used to. Adjust to what you tolerate.

When to contact your care team

Reach out if nausea, vomiting, or diarrhea keeps you from eating or drinking normally, or if constipation does not ease. Seek urgent care for severe abdominal pain that does not go away, repeated vomiting, or signs of dehydration such as very dark urine, dizziness on standing, or a racing heart.

Support from your provider
