Mounjaro (Tirzepatide) Diet Plan: A Week of Small, Protein-First Meals

I wrote this Mounjaro diet plan as five small meals a day, each starting with a protein food, and set a full week out in grams. It runs from 1,509 to 1,678 kcal and 105 to 119 g of protein a day. Mounjaro and Zepbound are two names for one drug, tirzepatide, so a single plan serves both.

Is a Mounjaro diet plan different from a Zepbound diet plan?

In the US the Mounjaro label covers type 2 diabetes. The Zepbound label covers weight reduction and asks for use with a reduced-calorie diet and more physical activity. The NHS lists Mounjaro as the UK brand. With one molecule behind both names, the stomach effects and the food advice match.

Neither label gives you a menu, so I haven’t invented a special one. The research offers a pattern, which the GLP-1 diet guide lays out: regular small meals, protein first, nutrient-dense food, enough fluid. This plan is that pattern in grams. The same pattern built around semaglutide is the Ozempic diet menu.

One boundary before the table. The NHS page says low blood sugar is more likely when tirzepatide is taken with other diabetes medicines. If you take any, ask the team that prescribes them before you change when or how much you eat.

What does a week of small, protein-first meals look like?

Seven days, five meals each, protein food on the fork first. Every day sits above 1,500 kcal, and that’s where I stop. The joint advisory flags vitamin and mineral gaps below 1,200 kcal a day for women and below 1,800 for men. This week clears the women’s line, and men can add the extras further down.

On the clock, I space the meals three hours apart: 7:30, 10:30, 1:30, 4:30 and 7:30. That sits inside the advisory’s every 3–4 hours. Shift the whole grid to match your waking day, but keep the gaps.

Across the week the average is 1,587 kcal and 113 g of protein, and the largest single meal is 457 kcal. Vomiting is more likely after large meals, which is why dinner isn’t the main event on any day. Protein works out to between 26% and 30% of each day’s energy.

Every weight comes from a USDA record, and cooked foods use the cooked weight. Here are the same foods ranked by protein per 100 kcal, so you can swap like for like.

Food (state)	Protein per 100 g	Energy per 100 g	Protein per 100 kcal
whey protein powder, dry	78.1 g	352 kcal	22.2 g
canned light tuna	19.0 g	90 kcal	21.1 g
braised chicken breast	32.1 g	166 kcal	19.3 g
Greek yogurt, nonfat	10.3 g	61 kcal	16.9 g
cottage cheese, lowfat 2%	11.0 g	84 kcal	13.1 g
boiled spinach	3.0 g	23 kcal	12.9 g
firm tofu, raw	17.3 g	144 kcal	12.0 g
baked salmon	22.1 g	206 kcal	10.7 g
lowfat kefir	3.8 g	43 kcal	8.8 g
eggs, hard-boiled	12.6 g	155 kcal	8.1 g
lentils, boiled	9.0 g	116 kcal	7.8 g
boiled broccoli	2.4 g	35 kcal	6.8 g
2% milk	3.4 g	50 kcal	6.7 g
tomato	0.9 g	18 kcal	4.9 g
whole-wheat bread	12.3 g	254 kcal	4.8 g
cucumber	0.6 g	14 kcal	4.5 g
almonds	21.1 g	579 kcal	3.7 g
cooked oatmeal	2.5 g	71 kcal	3.6 g
boiled potato	1.9 g	87 kcal	2.1 g
white rice, cooked	2.7 g	130 kcal	2.1 g
strawberries	0.6 g	33 kcal	2.0 g
orange	0.9 g	47 kcal	1.9 g
blueberries	0.7 g	57 kcal	1.2 g
banana	0.7 g	88 kcal	0.8 g
olive oil	0.0 g	884 kcal	0.0 g

Swapping is simple. Trade a food for one with similar protein per 100 kcal, keep the grams of protein roughly the same, and the day still adds up. For dishes you cook rather than assemble, GLP-1 diet recipes gives six portions with USDA numbers.

Oil is the exception. A tablespoon of olive oil weighs 13.5 g and carries about 119 kcal, so it pays to measure that before you measure the vegetables.

Why does the plan put protein first?

Eating the protein-rich food first in a meal, the advisory notes, helps enough of it get eaten. That matters on a smaller appetite. A plate you can’t finish is the plate where the protein got left behind.

For the numbers, the 2025–2030 Dietary Guidelines for Americans set protein at 1.2–1.6 g per kilogram of body weight a day. For a 70 kg (154 lb) adult that is 84–112 g. This plan averages 113 g, which fits anyone from 71 to 94 kg. Outside that range, scale the protein foods up or down and leave the rest. Choosing the weight behind that 1.2–1.6 g is worked through in how to work out your protein grams on tirzepatide.

There’s a ceiling too. The Acceptable Macronutrient Distribution Range tops out at 35% of calories from protein, and protein carries 4 kcal per gram. On a 1,500 kcal day that ceiling is 131 g. On 1,200 kcal it’s 105 g. So a big person on a small appetite can hit 1.6 g/kg and still bump against the cap. A 90 kg adult at 1.6 g/kg needs 144 g, which is 38% of 1,500 kcal.

Muscle is the reason to care. In the STEP 1 semaglutide trial, 5.3 kg of the 13.6 kg lost, or 38%, was lean mass, according to the advisory. It adds that protein alone is likely not enough to protect muscle and recommends strength training at least three times a week plus 150 minutes of moderate aerobic activity. Food is half of that deal. The advisory’s modeling puts muscle at 10–15% of the weight lost for women and 20–25% for men when there’s no structured strength training.

The protein calculator gives your own figure, from 1.2 g per kg with a 60 g minimum.

How do I change the week when my appetite changes?

Side effects come in waves, and the advisory says they’re most likely when treatment starts or the dose goes up. In the Zepbound label trials, nausea ran from 25% to 29% across the treatment groups against 8% on placebo. When a wave arrives, keep the meal times and soften the food.

When	Swap	Where it comes from
Nausea	A small breakfast, ginger or peppermint tea, no fatty or high-fiber food for the first few days, and yogurt or cottage cheese in place of beans	Advisory, except the bean swap, which is mine
Constipation	More fluid, fiber from food, prunes or other dried fruit	Joint advisory
Diarrhea	Smaller meals with less fat	Joint advisory
Very low appetite	Keep all five meal times, eat the protein food, leave some of the starch	My rule of thumb

Lentils show up at lunch on five days, and they’re the fiber-heavy item in the plan. A 200 g portion brings 15.8 g of fiber and 18.0 g of protein for 232 kcal. In a rough week, swap it for 80 g of chicken and 70 g of rice, which gives 27.6 g of protein for 224 kcal and almost no fiber. Bring the lentils back when your stomach settles.

Some weeks go the other way and you want more food. Add one of these. Banana (100 g) with almonds (15 g) brings 175 kcal and 3.9 g of protein. An egg (100 g) with a slice of whole-wheat bread (32 g) brings 236 kcal and 16.5 g. The advisory’s 1,800 kcal line for men sits about 213 kcal above this week’s average, so one of these a day covers most of the gap.

Eating less than this plan on most days does happen, and the people to tell are your prescriber or a dietitian. Dehydration from vomiting or diarrhea can cause kidney problems, and the Zepbound label says to drink fluids and to contact your healthcare provider right away if nausea, vomiting or diarrhea doesn’t go away.

Who should skip a template like this?

Anyone for whom food is a medical matter. With kidney disease your doctor sets the protein target, and pregnancy or breastfeeding changes the numbers too. The plan isn’t meant for anyone under 18, because the advisory says tirzepatide is approved for obesity in adults aged 18 and over.

The advisory also calls a restrictive eating disorder a general contraindication for these medicines. It says anyone with a history of disordered eating should see an obesity medicine specialist and an eating disorders specialist before starting. A week of gram-weighted meals can feed that pattern. If weighing food has started to feel like a compulsion, put the scale away.

If counting calories has started to feel hard to stop, or eating feels out of control, talk to someone: ANAD in the US (1-888-375-7767), Beat in England (0808 801 0677), NEDIC in Canada (1-866-633-4220) or the Butterfly Foundation in Australia (1800 33 4673). If you’re in danger right now, call your local emergency number. Other UK numbers and crisis lines are on our crisis support page.

Run the plan for one week and write down which meals you finished and which you pushed around the plate. Keep the finished ones and rebuild the rest around the same protein foods, until what’s left is a week you could still follow on a busy Wednesday.
