| Food | Why to Skip It | Eat This Instead |
|---|---|---|
| #1. Butter | About 11.5 g fat per tablespoon, and Lilly’s Zepbound tips name butter as a fatty food to avoid when nausea hits. | Saute in a splash of broth, or measure 1 tsp of olive oil instead of eyeballing a pat. |
| #2. Cheddar Cheese | About 9 g fat per 1 oz slice, and cheese is the other food Lilly calls out by name for nausea. | A tablespoon of grated Parmesan brings big flavor for under 2 g fat. |
| #3. Sour Cream | About 5 g fat per 2 tbsp, and full-fat dairy toppings may sit heavy while your stomach empties slowly. | Plain nonfat Greek yogurt with a pinch of salt tastes close on tacos and potatoes. |
| #4. Ranch Dressing | About 130 calories per 2 tbsp, nearly all of it from fat, and most people pour more than that. | Thin a spoon of hummus with water and dill for a lighter veggie dip. |
| #5. Mayonnaise | About 10 g fat per tablespoon, which can turn a lean tuna or chicken salad into a heavy lunch. | Dijon mustard and chopped pickles add tang to tuna or chicken salad with almost no fat. |
| #6. Peanut Butter From the Jar | About 16 g fat per 2 tbsp, and spoonfuls straight from the jar rarely stop at two. | Powdered peanut butter stirred into oats keeps the flavor with a fraction of the fat. |
| #7. Butter Croissants | About 230 calories in a medium croissant, with nearly half of them coming from butter fat. | A slice of plain toast, one of the bland foods Lilly suggests for queasy days. |
| #8. Cheesecake | About 18 g fat per slice, plus a dense, sweet richness that may linger in a slow stomach. | Try a lighter pick from these GLP-1 dessert ideas, or a cup of berries. |
| #9. Pork Spareribs | About 26 g fat per 3 oz of braised ribs, one of the fattiest cuts at any cookout. | Pork tenderloin is one of the leanest pork cuts and takes the same dry rub. |
| #10. Pepperoni | About 13 g fat per ounce, roughly 15 slices, and the grease pools on pizza and subs. | Diced grilled chicken or turkey pepperoni makes a lighter pizza topping. |
| #11. Loaded Nachos | About 19 g fat in 6 to 8 cheese-topped chips, before the sour cream or ground beef goes on. | A small burrito bowl with rice, grilled chicken, and a spoon of beans. |
| #12. Coconut Milk Curry | About 48 g fat per cup of canned full-fat coconut milk, and one can often goes into the whole pot. | Use light coconut milk and cut it half and half with chicken broth. |
| #13. Cream Soups and Chowders | Heavy cream adds about 5.5 g fat per tablespoon, and creamy chowders use it by the cup. | Brothy chicken noodle or vegetable soup, close to the chicken broth Lilly lists for diarrhea days. |
| #14. Pork Rinds | About 520 mg sodium per ounce, and since they are fried pork skin, the fat and salt arrive together. | A hard-boiled egg with a few whole-grain crackers for a salty, crunchy snack. |
| #15. Instant Ramen | Often 1,500 mg sodium or more in a full package, and the noodles are usually flash-fried before drying. | Rice noodles in low-sodium chicken broth with shredded chicken and spinach. |
| #16. Whole Milk Lattes | About 12 g lactose per cup of whole milk, and Lilly suggests limiting dairy if diarrhea shows up. | Order it with lactose-free skim or unsweetened almond milk instead. |
| #17. Vanilla Ice Cream | About 7 g fat and 137 calories per half-cup, mixing dairy, fat, and sugar in one cold scoop. | Frozen grapes or frozen banana coins give you a cold, sweet bite. |
| #18. Sugar-Free Candy | The FDA requires a laxative warning on foods that could push daily sorbitol to 50 g, and tirzepatide already lists diarrhea. | Fresh berries cover a sweet craving without any sugar alcohols. |
| #19. Energy Drinks | About 160 mg caffeine in many 16 oz cans, and Cleveland Clinic suggests limiting caffeine when diarrhea shows up. | Ginger tea or decaf green tea, sipped slowly between meals. |
| #20. Classic Sports Drinks | About 34 g sugar in a 20 oz bottle, a lot of sugar to drink when your appetite is already low. | One of these electrolyte powders for GLP-1 mixed into still water. |
| #21. Regular Cola | About 39 g sugar per 12 oz can, plus carbonation in a stomach that already empties slowly. | Still water with cucumber slices and a sprig of mint. |
| #22. Seltzer and Sparkling Water | Zero calories, but the bubbles add gas, and belching hit 4% to 5% of Zepbound trial patients versus 1% on placebo. | Plain still water, sipped between meals rather than gulped with them. |
| #23. Hard Seltzer | About 5% alcohol in a typical 12 oz can, so alcohol and carbonation land in the same sip. | A mocktail of still water, muddled berries, and fresh mint over ice. |
| #24. A Second Glass of Wine | Each 5 oz glass holds about 14 g of alcohol, and Cleveland Clinic lists alcohol among drinks to limit with diarrhea. | Stop at one small glass with food, or pour a caffeine-free herbal tea. |
| #25. Caramel Blended Coffee Drinks | A 16 oz caramel blended coffee with whipped cream can run about 380 calories and over 50 g sugar. | A cold shake made with one of these protein powders for GLP-1. |
| #26. Pancakes in Syrup | Maple syrup carries about 12 g sugar per tablespoon, and a short stack can soak up three or four. | A savory plate from these GLP-1 breakfast ideas, like eggs with toast. |
| #27. Milk Chocolate Bars | About 24 g sugar in a 1.55 oz bar, and chocolate may worsen reflux, which hit up to 5% of Zepbound trial patients. | A half-cup of strawberries with a spoon of nonfat yogurt. |
| #28. Orange Juice | About 21 g sugar per cup with the fiber stripped out, and its acid may sting if heartburn flares. | A whole pear or apple slices, which keep the fiber that juice leaves behind. |
| #29. Pretzels | About 23 g carbs but only about 3 g protein per ounce, which crowds out protein when you can only eat a little. | Roasted edamame, or another pick from this high-protein foods list. |
| #30. Big Bowls of Black Beans | About 15 g fiber per cooked cup, and a sudden fiber jump may bring gas and bloating after a dose. | Start with a quarter-cup of rinsed beans stirred into soup and build up slowly. |
| #31. Raw Broccoli | About 2.4 g fiber per raw cup plus raffinose, a sugar gut bacteria turn into gas, and bloating hit up to 4% on Zepbound. | Steamed carrots or peeled zucchini, cooked until soft. |

FAQs
These quick answers cover nausea, alcohol, dose increases, and drinks for anyone sorting out foods to avoid on Zepbound and Mounjaro.
1. What foods make Zepbound nausea worse?
Fatty, greasy, and very rich foods are the usual suspects, and Lilly’s own tips name butter and cheese. Nausea showed up in 25% to 29% of people in Zepbound weight-loss trials versus 8% on placebo. Smaller meals, plus skipping the foods to avoid on Zepbound and Mounjaro here, may help many people feel steadier.
2. Can I drink alcohol on Mounjaro or Zepbound?
The Zepbound label has no specific alcohol warning, but alcohol may add to dehydration and stomach upset, and it may raise low blood sugar risk if you also take insulin or a sulfonylurea. That is why hard seltzer and extra wine made my foods to avoid on Zepbound and Mounjaro list. Ask your prescriber what fits.
3. Why do foods to avoid on Zepbound and Mounjaro matter most after a dose increase?
Lilly says most nausea, vomiting, and diarrhea in studies happened while the dose was raised, then eased over time. Doses usually start at 2.5 mg weekly and climb in 2.5 mg steps after at least 4 weeks. Cleveland Clinic suggests eating lighter for the 24 hours before a first dose or a step up.
4. Does tirzepatide cause diarrhea or constipation?
It can cause either one. In Zepbound trials, diarrhea hit 19% to 23% of people and constipation 11% to 17%, versus 8% and 5% on placebo. Sugar-free candy, energy drinks, and big bowls of beans are foods to avoid on Zepbound and Mounjaro when either shows up. Lilly also suggests plenty of clear fluids.
5. Are Zepbound and Mounjaro the same medicine?
Both are once-weekly tirzepatide injections from Eli Lilly. Mounjaro is approved for type 2 diabetes, while Zepbound is approved for weight management and for obstructive sleep apnea in adults with obesity. Because the drug is the same, the foods to avoid on Zepbound and Mounjaro overlap, though diabetes medicines may call for extra blood sugar care.
6. What should I drink instead of soda on tirzepatide?
Still water is the easiest pick, and Lilly suggests 8 to 10 glasses of clear fluids a day if diarrhea shows up. Zero-sugar electrolyte mixes, ginger tea, and decaf herbal tea also work well. Soda, seltzer, and sweet coffee drinks sit near the top of my foods to avoid on Zepbound and Mounjaro list.
7. Can I still eat my favorite foods on Zepbound?
Many people still enjoy favorite foods in smaller portions, especially once a dose increase settles. Lilly suggests splitting three meals into four or more smaller ones and stopping when you feel full. Think of the foods to avoid on Zepbound and Mounjaro as foods to pause or shrink for now, not a lifelong ban.
