What to eat on Zepbound: a food guide for tirzepatide

Zepbound changes how much you want to eat, so what you do eat matters a little more. This guide covers the food side only: what to put on your plate, what to keep nearby on harder days, and how Imi can help. Anything about your dose belongs with your prescriber.

What is Zepbound?

Zepbound is tirzepatide, a once-weekly injection made by Eli Lilly and Company.

Its FDA label says it’s used alongside a reduced-calorie diet and more physical activity to reduce excess body weight and keep it off long term. That covers adults with obesity, and adults with overweight who have at least one weight-related health condition. It’s also approved for moderate to severe obstructive sleep apnea in adults with obesity.

Why does my appetite change?

Tirzepatide works on the hormone signals that help steer hunger, and it slows how quickly your stomach empties.

The prescribing information describes GLP-1 as a natural regulator of appetite and calorie intake, and says Zepbound delays gastric emptying. Many people feel full after a few bites, so smaller plates often feel better.

How do I get enough protein and fluids?

Eat the protein on your plate first, and sip fluids steadily through the day.

• Protein. A 2025 joint advisory from four nutrition and obesity medicine groups (ACLM, ASN, OMA and TOS) suggests 1.2 to 1.6 grams per kilogram of body weight a day while losing weight.
• Fluids. Nausea, vomiting and diarrhea can cost you fluids. The Zepbound Medication Guide says this dehydration may cause kidney problems, and that drinking fluids helps lower the chance.
• Easy protein. Greek yogurt, eggs, cottage cheese, tofu, canned fish, milk, or a soup with beans or chicken.

The protein calculator works out your number, and the protein guide has more ideas.

What can I eat when I’m queasy or not hungry?

Small, plain, lower-fat foods, eaten slowly, stopping as soon as you feel full.

The advisory suggests smaller, more frequent meals and avoiding fatty foods in the first few days when nausea is an issue. A 2022 expert consensus on stomach side effects adds smaller portions and stopping when you feel full. Some people find these sit well:

If nothing sounds good, a glass of milk or a small smoothie still counts. There’s more in gentle meals for queasy days and when you’re not hungry.

Which foods can feel harder?

Greasy or fried food, very large portions, alcohol and fizzy drinks are the usual ones.

• Rich and fried meals. With slower stomach emptying, heavy food can sit for a while. The advisory suggests avoiding large or high-fat meals when diarrhea is a problem.
• Big portions. Stop when you’re full, even if the plate isn’t empty.
• Alcohol. The advisory notes it may make nausea and reflux worse.
• Fizzy drinks. The consensus suggests leaving out soft drinks when stomach symptoms flare.

None of these are off-limits forever. See foods that can feel harder for easy swaps.

Does injection day or a dose step change what I eat?

It can. The label says most nausea, vomiting and diarrhea happened while the dose was being increased, and eased over time.

The label also says Zepbound can be taken with or without meals, so there’s no special food rule for shot day. Still, some people notice a pattern in the day or two after their shot, or after a dose step. If that’s you, plan your gentlest, most familiar meals for those days and keep easy protein in the fridge. Your dose and schedule are for you and your prescriber to decide. The injection day guide has more.

What helps with constipation?

Fiber from food, added slowly, plus plenty of fluids.

Constipation is one of the common side effects listed on the Zepbound label. The NIDDK lists too little fiber, too little fluid and not enough movement among its everyday causes. It suggests adding fiber a little at a time and drinking water and other liquids to help the fiber work. Oats, beans, lentils, berries and pears are good places to start. Ask your doctor or pharmacist before trying a supplement or laxative. See constipation and fiber.

How does Imi help?

Imi plans the food side of your Zepbound week.

• Your dose in one place. Log each shot and see an estimated level, injection site rotation and how much supply you have left.
• Quick check-ins. Note side effects and food noise in a tap or two.
• Gentler days. Lighter, familiar meals planned for the days after a dose.
• Protein and water first. Both targets sit at the top of your day.

Imi helps with food. Your prescriber handles your medication. For the bigger picture, see eating well on a GLP-1 or visit the GLP-1 hub.
