Mounjaro Diet Recipes — Free Meal Ideas for Weight Loss
If you're taking Mounjaro (tirzepatide) in the UK, planning simple, nutritious meals is essential to support your weight loss journey.

This guide offers free, practical meal ideas and recipe guidance for adults taking Mounjaro, helping you make the most of your treatment. Remember, individual results vary, and your GP or prescriber can offer personalised dietary advice based on your health.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Best Foods to Eat While Taking Mounjaro
When taking Mounjaro, focus on nutrient-dense, protein-rich foods that keep you satisfied with smaller portions. Good choices include lean meats (chicken breast, turkey, fish), eggs, Greek yoghurt, lentils, and beans. Include plenty of non-starchy vegetables — broccoli, spinach, courgettes, peppers, and cauliflower — which are low in calories but high in fibre and nutrients. Whole grains like brown rice, oats, and wholemeal bread provide sustained energy without causing blood sugar spikes. Many people taking Mounjaro experience nausea or reduced appetite, so eating smaller, more frequent meals can help. Avoid high-fat, sugary, and heavily processed foods, as these may worsen stomach discomfort. Stay hydrated with water, herbal tea, and unsweetened beverages.

Breakfast ideas include scrambled eggs with spinach, porridge with berries, or Greek yoghurt with nuts.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Can I eat normally while taking Mounjaro?
Mounjaro may reduce your appetite, so you may naturally eat less. However, you'll still need to follow a reduced-calorie diet to achieve weight loss. Eating slowly, in smaller portions, and choosing nutrient-dense foods helps prevent nausea and supports sustainable results. Your prescriber can advise on specific dietary requirements for your situation.
What foods should I avoid with Mounjaro?
Avoid high-fat, greasy, and sugary foods, as these may worsen stomach discomfort, nausea, and diarrhoea — common side effects of Mounjaro. Spicy foods, caffeine, and alcohol may also cause stomach upset. Focus on lean proteins, vegetables, and whole grains instead. Keep a food diary to identify personal triggers.
Is Mounjaro the same as Wegovy?
No. Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist, while Wegovy (semaglutide) is a GLP-1 agonist only. Both are prescription-only weight management injections available in the UK. Mounjaro uses a KwikPen device and may offer different results than Wegovy — your prescriber will determine which is appropriate for you.
How much weight can I expect to lose with Mounjaro?
Clinical trials (SURMOUNT-1) showed average weight loss of 15–21% of body weight on Mounjaro, depending on dose, alongside a reduced-calorie diet and exercise. However, individual results vary significantly. Your GLP-1 weight loss calculator can help estimate potential outcomes based on your starting weight and dose.
Do I need a prescription for Mounjaro in the UK?
Yes, Mounjaro is prescription-only in the UK. Access is available through NHS specialist weight management services (tier 3) with a waiting list, or through private online prescribing following a clinical assessment. Either route requires a licensed UK prescriber to confirm you're eligible based on your BMI and health status.
