A useful Mounjaro diet plan is three small, protein-first meals, with fruit or vegetables, a modest high-fiber carbohydrate and an optional protein snack each day. The plan below gives you a complete week to copy, then shows you how to adapt it when appetite or digestion changes.
In the UK, Mounjaro is the tirzepatide brand used for type 2 diabetes and weight management. In the US, tirzepatide is sold as Mounjaro for type 2 diabetes and Zepbound for weight management. This page is food education, not a prescription: your prescriber or dietitian should personalize your intake if you have diabetes, kidney disease, digestive disease, food allergies, a history of disordered eating or another clinical need.
What makes this plan different from a standard weight-loss menu?
Mounjaro can reduce appetite and make you feel full sooner. Its UK patient information leaflet also lists nausea, diarrhea, vomiting, abdominal pain and constipation among common or very common effects, depending on why it is prescribed. A huge salad or a rigid, low-calorie menu may therefore be much harder to manage than it looks on paper.
This plan uses small starting portions and puts the protein food first. Protein matters because weight loss can include lean tissue as well as fat. In the SURMOUNT-1 body-composition substudy, Look and colleagues found substantial fat-mass reduction with lean mass proportionally preserved, although some lean mass was also lost. The joint clinical advisory led by Mozaffarian and published by four nutrition and obesity organizations recommends adequate protein and resistance training to support lean mass; protein alone is not a shield against muscle loss.
There is no single evidence-based protein number for every person taking a GLP-1 medicine. The joint advisory summarizes several approaches:
| Approach | Amount discussed in the advisory | Important limitation |
|---|---|---|
| General adult minimum reference | 0.8 g per kg of body weight per day | Designed to cover basic needs, not specifically active weight loss |
| Proposed range during active weight loss | 1.2–1.6 g per kg of body weight per day | Actual body weight may overestimate needs for some people with obesity |
| Practical absolute target proposed by experts | 80–120 g per day | Still needs individual adjustment; it may be unrealistic during significant nausea |
Here is what the proposed 1.2–1.6 g/kg range looks like at three example body weights:
| Body weight | Protein at 1.2–1.6 g/kg per day |
|---|---|
| 70 kg (154 lb / 11 st 0 lb) | 84–112 g |
| 90 kg (198 lb / 14 st 2 lb) | 108–144 g |
| 110 kg (243 lb / 17 st 5 lb) | 132–176 g |
Use our protein calculator to find a sensible starting point, then discuss it with your prescriber or a registered dietitian if you have kidney disease, you are older or frail, or eating has become difficult. As written, the menu sits at or just under the 80 g floor of that practical range on most days. It is a skeleton, not a universal target, and heavier readers must scale it up with the portion guidance in the kg/lb/stone table above.
What is the 7-day Mounjaro diet plan?
Protein figures below are estimates, not laboratory values. Brands and recipes differ, so check the label; meat and fish amounts are cooked weights. Start with the portion shown, eat slowly, and stop at comfortable fullness. Save the rest rather than pushing through fullness. If three meals feel like too much, split them into smaller sittings.
| Day | Breakfast | Lunch | Dinner | Optional snack | Approx. daily protein |
|---|---|---|---|---|---|
| Day 1 | Plain skyr, 180 g, with berries and a spoonful of oats (18 g) | Tuna in spring water, 70 g drained, a small baked potato and cucumber (16 g) | Chicken breast, 100 g cooked, with mash and carrots (29 g) | Cottage cheese, 150 g pot (15 g) | 78 g |
| Day 2 | Two softly scrambled eggs, about 100 g without shells, on one slice of wholemeal (whole-wheat) toast (16 g) | Prawns (shrimp), 100 g cooked, and couscous bowl with tomato and cucumber (24 g) | Baked cod, 110 g cooked, peas and a few new potatoes (25 g) | Plain Greek yogurt, 150 g (15 g) | 80 g |
| Day 3 | Small overnight oats made with skyr, 150 g, and milk, 100 ml (20 g) | Chicken and vegetable soup made with chicken, 100 g cooked, with one slice of bread (28 g) | Salmon fillet, 100 g cooked, microwave rice and courgette (zucchini) (23 g) | Shelled edamame, 80 g (9 g) | 80 g |
| Day 4 | Cottage cheese, 150 g, on one slice of toast with sliced tomato (20 g) | Lentil soup, 250 g, with one boiled egg, about 50 g without shell (18 g) | Tofu, 150 g, stir-fried with soft vegetables and rice (24 g) | Plain Greek yogurt, 150 g (15 g) | 77 g |
| Day 5 | Small porridge (oatmeal) topped with Greek yogurt, 150 g (20 g) | Half a chicken salad sandwich made with chicken, 40 g cooked, plus vegetable sticks (15 g) | Small lean-beef shepherd's pie made with beef, 85 g cooked, with peas (27 g) | Milk or fortified soy drink, 200 ml (7 g) | 69 g |
| Day 6 | Two eggs, about 100 g without shells, with baked beans, 140 g (20 g) | Half a tuna and sweetcorn (corn) sandwich made with tuna, 50 g drained, with tomato soup (14–15 g) | Turkey meatballs containing turkey, 85 g cooked, pasta and tomato sauce (27 g) | Plain skyr, 150 g (15 g) | 76–77 g |
| Day 7 | Plain skyr, 150 g, with banana slices (15 g) | Baked beans, 200 g, and grated cheese, 25 g, on one slice of toast (20 g) | Baked haddock, 110 g cooked, mashed peas and a few potato wedges (25 g) | Cottage cheese, 100 g, with milk, 200 ml (19 g) | 79 g |
| Approximate energy for the menu as written | How to use it |
|---|---|
| 1,050–1,300 calories a day, including the optional snack | Treat this menu as a floor: add portions or snacks to it, not a ceiling. Recipes, brands and exact portions can move the estimate considerably, and this will not meet every adult's energy needs. |
| Signals your intake may be too low | What to do |
|---|---|
| After the first weeks of treatment, sustained loss much faster than about 0.5–1 kg / 1–2 lb per week, especially with dizziness or fatigue; persistent cold intolerance; or hair shedding | Speak to your prescriber, GP or dietitian, especially if you are struggling to eat enough. |
Water, tea and coffee can sit alongside the plan according to your tolerance. The NHS Eatwell Guide's general hydration advice is shown below, but illness, hot weather, exercise and some medical conditions change fluid needs. If your clinician has given you a fluid limit, follow that instead.
| General NHS guide | What it means in practice |
|---|---|
| 6–8 cups or glasses of fluid through the day | Sip regularly; water and lower-fat milk count, as do sugar-free drinks, tea and coffee |
What about alcohol, caffeine and fizzy drinks?
| Drink | Practical approach |
|---|---|
| Alcohol | It adds calories and can worsen nausea, reflux or dehydration. Drink less or skip it when symptoms are active, and ask your diabetes team about alcohol if you use medicines that can cause low blood sugar. |
| Caffeinated tea, coffee and energy drinks | Tea and coffee can count towards fluid intake, but reduce caffeine if it worsens nausea, reflux, anxiety or sleep. Energy drinks can contain high amounts, so check the label. |
| Fizzy drinks, including diet or sugar-free versions | They can contribute to fluid intake, but bubbles may worsen bloating, fullness or reflux. Let them go flat or choose a still drink if that feels better. |
How do you adapt the plan without starting again?
Think in building blocks, not perfect recipes. Each main meal needs a protein anchor you can tolerate; the rest can flex.
| If the planned food does not suit you | Similar protein-first swap |
|---|---|
| Chicken or turkey | Fish, eggs, tofu, tempeh or mycoprotein pieces (such as Quorn) |
| Tuna, prawns or white fish | Chicken, cottage cheese, tofu or beans plus yogurt |
| Skyr or Greek yogurt | Lactose-free high-protein yogurt or fortified soy yogurt; compare labels |
| Cow's milk | Fortified soy drink; most oat and nut drinks contain much less protein |
| Bread, pasta or rice | Potato, oats, couscous or another tolerated grain |
| Raw vegetables | Cooked carrots, zucchini, peeled squash or vegetable soup |

What should you do on a low-appetite day?
Do not turn low appetite into a contest to eat as little as possible. Choose the smallest useful version of a meal: skyr, an egg on toast, a mug of chicken soup, cottage cheese, or half a sandwich. Cold foods may be easier if cooking smells trigger nausea. Sip fluids between meals if drinking with food makes you uncomfortably full.
Royal Devon University Healthcare NHS Foundation Trust advises small, frequent meals and mild foods for nausea, with fluids to protect against dehydration. If appetite stays very low, you are eating very little, or you are losing weight faster than your clinical team expects, contact your GP, doctor, prescriber or dietitian rather than trying to force this menu.
What if nausea, constipation or diarrhea changes the plan?
| What you are experiencing | Food adjustment to try | When to get help |
|---|---|---|
| Nausea or early fullness | Smaller meals; cool or plain foods; eat slowly; avoid lying down just after eating | Contact your prescriber if symptoms persist or stop you eating and drinking adequately |
| Constipation | Gradually add oats, kiwi, vegetables, pulses or whole-wheat bread; keep fluids regular | Ask your pharmacist, GP or prescriber if it does not improve |
| Diarrhea or vomiting | Prioritize fluids; temporarily choose plain, lower-fat, lower-fiber foods if better tolerated | Seek medical advice if it persists, you cannot keep fluids down or you have signs of dehydration |
Fiber is useful, but more is not always better overnight. The NHS general target for adults is listed below. Increase gradually, particularly if you already feel bloated, and drink enough for fiber to do its job.
| General NHS fiber target | How to approach it |
|---|---|
| 30 g per day for adults | Build up gradually from foods you tolerate rather than adding a large amount at once |
Severe, persistent abdominal pain—especially pain reaching through to the back, with or without nausea and vomiting—needs urgent medical help because it can be a sign of acute pancreatitis. This warning comes directly from the UK Mounjaro patient leaflet. Do not try to manage it with meal swaps.
If you use insulin or a sulfonylurea for diabetes, the same leaflet warns that tirzepatide can increase the risk of low blood sugar in combination with those medicines. Follow the eating and hypo-treatment plan your diabetes team gave you; a generic internet menu cannot safely replace it.
What should go on your shopping list?
Buy fewer items and repeat them. That keeps the week practical and reduces waste when your appetite changes.
- Easy proteins: eggs, skyr or Greek yogurt, cottage cheese, tuna, chicken, white fish, salmon, prawns, tofu and lentil soup.
- Gentle carbohydrates: oats, wholemeal (whole-wheat) bread, potatoes, rice, couscous and pasta.
- Fruit and vegetables: berries, bananas, cucumber, tomatoes, carrots, courgette (zucchini), peas and any alternatives you digest comfortably.
- Backup foods: soup, frozen fish, microwave rice, canned tuna, frozen vegetables and plain crackers for days when cooking feels like too much.

FAQ
Is there an official Mounjaro diet plan?
No. Mounjaro does not require a branded menu or ban a specific food group. A useful plan is balanced, nutritionally adequate, portioned to your appetite and adjusted to your medical needs. Your prescriber's advice takes priority over this example.
Do I need to count calories on Mounjaro?
Not necessarily. Calories still matter to weight change, but aggressive restriction can make it harder to meet protein and micronutrient needs when appetite is already low. Start with regular, small, balanced meals. Ask your prescriber or dietitian for an individualized calorie target if you need one.
Should I eat even when I am not hungry?
You do not need to finish a full plate, but repeatedly skipping food can make adequate nutrition difficult. Try a mini-meal or split one meal across the day. If you are consistently unable to eat enough, speak to your prescriber or GP.
Can vegetarians use this Mounjaro meal plan?
Yes. Use eggs and dairy if you eat them, plus tofu, tempeh, edamame, beans and lentils. Plant-based substitutes vary widely in protein, so check labels. A dietitian can help if your food range is becoming narrow.
Are protein shakes necessary on Mounjaro?
No. Food can cover protein for many people. A shake may be convenient when appetite is limited, but it is not automatically nutritionally complete and may not suit kidney disease or some digestive symptoms. Ask a clinician or dietitian before relying on supplements.
What foods should I avoid on Mounjaro?
There is no universal forbidden list. Large, rich, fried or very spicy meals worsen symptoms for some people, while others tolerate them. Notice your own pattern, reduce the portion or frequency of a trigger food, and avoid turning one uncomfortable meal into a permanent rule.
