Mounjaro, also called tirzepatide, is a weekly injection licensed in the UK to support weight loss. It works by reducing appetite and improving blood sugar control. Alongside this treatment, a healthy diet is essential to achieve the best results.

At South Ealing Pharmacy, we provide a private Weight Loss Service, including access to Mounjaro at different strengths ranging from 2.5mg to 15mg. Many patients in Ealing, Acton, Hanwell, Brentford and across West London want to know how to adapt their diet while taking this medication.

This guide explains how Mounjaro works, why a diet plan matters, which foods to focus on, and offers a sample 7-day meal plan.

What is Mounjaro and How Does it Help with Weight Loss

Mounjaro belongs to a group of medicines called GLP-1 and GIP receptor agonists. These hormones naturally occur in the body and help regulate appetite and blood sugar. By mimicking them, Mounjaro reduces hunger and slows digestion.

Clinical trials show that Mounjaro can support significant weight loss when combined with healthy eating. It is not a replacement for lifestyle changes but a tool to help patients stay on track.

Why a Diet Plan is Important on Mounjaro

Although Mounjaro reduces appetite, it does not control food choices. Without a balanced diet, patients may experience nutrient gaps.

Eating the right foods supports steady progress, maintains energy levels, and reduces the risk of side effects such as nausea or constipation.

A good diet ensures that even with smaller portions, the body receives enough protein, fibre, and vitamins.

Key Principles of a Mounjaro-Friendly Diet

A balanced diet is vital when appetite is lower. Key points include:

• High protein foods to maintain muscle and prevent cravings
• Fibre-rich vegetables and whole grains to support digestion
• Balanced carbohydrates, especially low glycaemic index options
• Healthy fats such as olive oil, nuts, and avocado
• Adequate hydration to keep digestion regular

Foods to Eat on Mounjaro

Certain foods work well with Mounjaro treatment. These include:

• Lean protein such as chicken, fish, tofu, and eggs
• Vegetables including spinach, broccoli, and peppers
• Whole grains like brown rice, oats, and quinoa
• Healthy fats including nuts, seeds, and olive oil
• Fruits such as berries, apples, and pears in moderate amounts

These foods provide nutrients and help you feel fuller for longer.

Foods to Limit or Avoid on Mounjaro

Some foods may reduce the effectiveness of treatment or worsen side effects. These include:

• Processed foods such as crisps, sweets, and fast food
• Sugary items including cakes, biscuits, and fizzy drinks
• Greasy or fried foods that are harder to digest
• Alcohol which may increase nausea and reduce weight loss benefits

Avoiding these helps the body adjust to smaller meal sizes more comfortably.
