What to eat on tirzepatide or semaglutide: a simple GLP-1 meal plan

Put protein first, eat smaller meals, and go easy on large, high-fat meals and alcohol, which can make stomach side effects worse. A 2025 joint advisory from four obesity and nutrition groups suggests a practical target of 80 to 120 grams of protein a day, fiber added slowly with plenty of fluids, and strength training to protect muscle. Every NexLife plan includes a personalized nutrition plan and a 1:1 coaching call.

  • 80–120 g of protein a day, eaten first
  • Small meals, every 3 to 4 hours if nausea hits
  • Strength training to protect muscle

Protein first

How much protein, and how to split it

27–40 g a meal80 to 120 g a day, over 3 meals.

From the 2025 joint GLP-1 nutrition advisory: 80 to 120 g a day as a practical target; 1.2 to 1.6 g per kg has also been proposed during weight loss. Have kidney disease? Ask your provider before you eat more protein.

The advisory gives 80 to 120 grams a day as a simple, practical target. Weight-based targets of 1.2 to 1.6 g per kilogram have also been proposed during weight loss, but at higher body weights they can overstate what you need.

A sample day

About 94 grams of protein, in four small meals

Protein rounded from USDA FoodData Central; your labels and portions may differ
MealWhat to eatProtein
BreakfastA 6-oz cup of plain Greek yogurt with berriesAbout 17 g
Lunch3 oz roasted chicken on a big salad with ½ cup lentilsAbout 35 g
Snack½ cup low-fat cottage cheese with fruitAbout 13 g
Dinner4 oz salmon, roasted vegetables and ½ cup quinoaAbout 29 g

Small appetite? Split these into five or six mini-meals and eat the protein part first. A 1-cup glass of milk adds about 8 g; a large egg, about 6 g.

Food fixes for common side effects

From the 2025 joint GLP-1 nutrition advisory
If you have…Try this
NauseaA small breakfast, then small meals every 3 to 4 hours. Skip large or high-fat meals.
ConstipationMore fluids, and add fiber gradually: prunes, other dried fruit, vegetables, beans. Ask your provider about magnesium.
DiarrheaFluids to stay hydrated; avoid large or high-fat meals until it settles.
Reflux or heartburnSmaller meals, and keep alcohol to a minimum.
Feeling full fastEat the protein on your plate first, so it doesn’t get left behind.

Call your provider if vomiting or diarrhea won’t stop, or you can’t keep fluids down. Dehydration can harm your kidneys.

Keep your muscle

Protein alone isn’t enough

  • Add strength training

    The advisory says higher protein alone is likely inadequate to preserve muscle without structured resistance or strength training.

  • Watch the nutrients that run low

    Iron, calcium, magnesium, zinc, and vitamins A, D, E, K, B1, B12 and C are nutrients of concern. Your provider may suggest a multivitamin.

  • Don’t under-eat

    Below about 1,200 calories a day for women or 1,800 for men, it gets hard to get enough vitamins and minerals.

GLP-1 eating questions

What should I eat on tirzepatide or semaglutide?

Protein at every meal, eaten first; vegetables, fruit and whole grains, with fiber added slowly; plenty of fluids; and small, regular meals. Go easy on large or high-fat meals and alcohol.

How much protein do I need on a GLP-1?

A 2025 joint advisory suggests a practical target of 80 to 120 grams a day. Weight-based targets of 1.2 to 1.6 g per kilogram have also been proposed during weight loss.

What foods make GLP-1 nausea worse?

Large meals and high-fat or greasy food are common culprits, and alcohol can worsen nausea and reflux.

Do I need supplements on a GLP-1?

Not always. The advisory lists nutrients that can run low, including iron, calcium, vitamin D and B12, and says supplements can be considered for people at risk. Ask your provider.

Should I exercise on tirzepatide or semaglutide?

Yes. Strength or resistance training helps protect muscle while you lose weight; protein alone likely isn’t enough.

Does NexLife help with nutrition?

Yes. Every plan includes a personalized GLP-1 nutrition plan and a 1:1 call with a certified wellness coach.

Important safety information

Compounded tirzepatide and semaglutide are not FDA-approved, and the FDA hasn’t reviewed them for safety, effectiveness or quality. A provider prescribes them only when they offer a significant difference for you compared with an FDA-approved product. Both medicines may cause thyroid tumors, including cancer: don’t use either if you or a family member has had medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).

Read the full safety information

In studies with rodents, both medicines caused thyroid tumors; it isn’t known whether they cause them in people. Tell your provider if you notice a lump or swelling in your neck, hoarseness, trouble swallowing or shortness of breath.

Serious side effects can include inflammation of the pancreas (pancreatitis), gallbladder problems, low blood sugar (especially with insulin or sulfonylureas), kidney problems from dehydration, severe stomach problems, serious allergic reactions, vision changes in people with type 2 diabetes, and a faster heart rate. Tell your care team before any surgery or procedure that uses anesthesia or deep sedation. Don’t combine either medicine with other GLP-1 medicines.

Tirzepatide can make birth control pills less effective: switch to a non-oral method, or add a barrier method such as condoms, for 4 weeks after you start and for 4 weeks after each dose increase. Both medicines may harm an unborn baby. Semaglutide should be stopped at least 2 months before a planned pregnancy. Tell your provider right away if you’re pregnant, planning to be, or breastfeeding.

This is a summary, not the complete safety information. Read the full Prescribing Information for FDA-approved tirzepatide (Zepbound) and semaglutide (Wegovy), and talk with your provider. You can report side effects to the FDA at 1-800-FDA-1088 or fda.gov/medwatch.
