Mounjaro contains tirzepatide, which works on two naturally occurring hormones: GLP-1 and GIP (glucose-dependent insulinotropic polypeptide). Together, these hormones help to:Reduce appetiteIncrease feelings of fullnessSlow stomach emptyingImprove blood sugar regulation

What's the difference between Mounjaro and Wegovy?

Both medications are effective treatments for weight management and work in similar ways to help reduce appetite and support weight loss.The main difference is that Wegovy works on GLP-1 receptors, whereas Mounjaro works on both GLP-1 and GIP receptors. Your doctor has recommended the medication that is most suitable for you based on your medical history, eligibility and clinical assessment.

Building Healthy Eating Habits

Your appetite may change while taking treatment, which can make it easier to make healthier choices and manage portion sizes.Focus on:Eating balanced mealsChoosing foods that keep you fuller for longerPrioritising proteinIncluding a variety of fruit and vegetablesStaying hydratedThere is no single “perfect” diet - the best approach is one that you can maintain long term.

Protein is an important part of your weight loss journey.When losing weight, your body can lose both fat and muscle. Eating enough protein alongside regular physical activity can help support muscle maintenance.Good sources of protein include:Lean meat and poultryFish and seafoodEggsGreek yoghurt and dairy productsBeans, lentils and pulsesTofu and other plant-based protein sourcesTry to include a source of protein with each meal where possible.

Drinking enough fluids is important, especially as reduced appetite may mean you naturally eat and drink less.Aim to:Drink water regularly throughout the dayIncrease your fluids if you are exercising or sweating more than usualPay attention to signs of dehydration, such as dizziness, dark urine or feeling unusually tiredStaying hydrated may also help reduce some common side effects, such as constipation.

Your Medication

At H3 Health, we currently prescribe Mounjaro® (tirzepatide) as part of our doctor-led weight management programme.

Both medications work by helping to regulate your appetite, so you feel fuller for longer and are less likely to overeat. They are designed to support sustainable weight loss alongside healthy eating and lifestyle changes.

During your consultation, your doctor has recommended and prescribed the medication they believe is most suitable for you, taking into account your medical history, treatment goals and clinical assessment.

Your Treatment Timeline

Starting treatment (Months 0–3)

Treatment begins at the recommended starting dose while your body adjusts to the medication. Changes in appetite and feelings of fullness are common. Before each prescription, a doctor will review progress and, if appropriate, gradually increase the dose while healthy eating and lifestyle habits are established. At around three months, you'll have a clinical review to discuss progress, side effects and whether the treatment plan should be adjusted.

Finding the right dose (Months 3–6)

If appropriate, the dose may continue to increase until the best balance of weight loss, appetite control and tolerability is achieved. Not everyone requires the highest dose, and many patients achieve excellent results on lower doses. By this stage, most people have settled into a sustainable routine and are continuing to build healthy habits.

Maintaining your results (Beyond 6 months)

Once a target weight has been reached, many patients continue treatment on the lowest effective dose to help maintain weight loss and reduce the risk of weight regain. Treatment is often continued long term, although the duration varies between individuals. Regular reviews with a doctor will determine whether treatment should be continued, adjusted or stopped.

What to Expect

What results can I expect?

Everyone responds differently to treatment.

Some patients notice changes to their appetite within the first few days, while others may take several weeks to experience the full effects. It's important to be patient and allow your body time to adjust, particularly as your dose gradually increases.

Many patients notice:

Feeling less hungry between meals
Feeling fuller sooner when eating
Reduced food cravings
Smaller portion sizes becoming more satisfying

Weight loss expectations

Weight loss varies from person to person and depends on many factors, including your starting weight, lifestyle, activity levels and how your body responds to treatment.

Rather than focusing on weekly changes, we encourage you to look at your progress over several months. Weight loss is rarely linear - it is completely normal to experience weeks where your weight stays the same or fluctuates slightly.

Your doctor will work with you to support steady, sustainable progress and help you achieve realistic long-term goals.
