When you decide to begin a weight loss journey, one of the first questions that comes to mind is often: how much weight can I lose in a month? At Shivas Pharmacy, we provide personalised support through our weight loss clinic in West Croydon, offering both natural approaches and prescription treatments such as Mounjaro. The answer to that question depends on a range of factors, including your starting weight, lifestyle, metabolism, and whether you use medical support.

This article explores the difference between natural weight loss and weight loss achieved with Mounjaro, so you can set realistic expectations and make informed decisions about your health.

Average First Month Results Without Medication

If you are aiming for healthy, sustainable weight loss without medication, the NHS recommends a gradual reduction of 0.5 to 1 kg per week. This equates to around 2 to 4 kg in a month. This rate helps ensure you are losing fat rather than muscle and reduces the risk of nutrient deficiencies or rebound weight gain.

In the first week, some people see slightly faster results due to the loss of water weight, especially if they have made significant changes to their diet. However, after this initial drop, progress usually slows to a steady and more predictable pace. Success in natural weight loss largely depends on:

• ✓  Maintaining a calorie deficit through diet changes
• ✓  Increasing physical activity to burn more calories
• ✓  Improving sleep quality and managing stress levels
• ✓  Staying consistent with healthy habits over time

Natural weight loss requires patience and perseverance. While the results may be slower than with medication, they can be highly sustainable when lifestyle changes are maintained.

What Mounjaro Users Can Expect In 4 Weeks

Mounjaro is a prescription medication that works by regulating appetite, improving blood sugar control, and slowing digestion. It helps reduce hunger and makes it easier to stick to smaller portions and a lower calorie intake.

In clinical trials and real-world use, some people using Mounjaro have reported losing between 3 to 6 kg in the first month. However, this can vary considerably depending on factors such as starting weight, adherence to dietary recommendations, and the dose prescribed.

The first few weeks on Mounjaro often focus on adjusting to the medication and starting at a lower dose to minimise side effects such as nausea or digestive discomfort. For many, appetite reduction is noticeable within the first week or two, which can lead to early weight loss.

It is important to note that while Mounjaro can accelerate results, it is not a standalone solution. It works best when combined with a balanced diet, regular movement, and a long-term commitment to healthy living.

Natural Weight Loss vs Mounjaro: A Side-By-Side Comparison

Understanding how these two approaches differ can help you have a more informed conversation with your prescriber and set realistic goals from the outset.

Factor	Natural Weight Loss	With Mounjaro
Average loss per month	2 to 4 kg	3 to 6 kg (first month)
Appetite control	Relies on willpower and habits	Significantly reduced by medication
Speed of results	Gradual and steady	Faster in early stages
Prescription required	No	Yes
Best suited for	Those with lower BMI or mild weight concerns	Adults with obesity or weight-related health conditions
Long-term sustainability	High when habits are maintained	High when combined with lifestyle changes

Combining Medication With Healthy Habits

The most successful weight loss journeys combine medical support with positive lifestyle changes. Even when using Mounjaro, building a foundation of healthy habits ensures you get the best results and are more likely to maintain them once the medication is reduced or stopped.

Healthy strategies to combine with Mounjaro include:

• ✓  Prioritising protein and fibre-rich foods to support satiety and muscle preservation
• ✓  Staying hydrated throughout the day
• ✓  Including regular physical activity such as walking, resistance training, or swimming
• ✓  Planning meals in advance to avoid impulsive eating
• ✓  Tracking progress through weight, measurements, and energy levels

At Shivas Pharmacy, our team in the weight loss clinic in West Croydon works with patients to create personalised plans that align medication with these healthy behaviours. This combined approach helps you maximise results while protecting your overall health.

Building On Your First Month’s Success

Whether you have lost 2 kg naturally or 5 kg with Mounjaro in your first month, the next step is to maintain momentum. Early weight loss can be motivating, but it is important to avoid unrealistic expectations for ongoing rapid results. After the initial few weeks, weight loss often slows as your body adjusts to a new calorie intake. If you are wondering what the longer-term journey looks like, our guide on how long you stay on Mounjaro for weight loss covers what to expect over time.

To continue progressing:

• ✓  Reassess your calorie needs as you lose weight
• ✓  Gradually increase activity levels to challenge your body
• ✓  Keep meals balanced and nutrient-dense
• ✓  Monitor your progress regularly to spot plateaus early

If you notice your weight loss slowing significantly, a consultation with our pharmacists can help identify the cause. Sometimes, small adjustments to diet, activity, or medication dose can get you back on track. Contact us today to find out how we can support your weight loss.

Frequently Asked Questions

How much weight can I realistically lose in a month without medication?

Most people following a healthy calorie deficit with regular exercise can expect to lose around 2 to 4 kg per month. The NHS recommends aiming for 0.5 to 1 kg per week as a safe and sustainable rate.

How much weight can I lose in the first month on Mounjaro?

Some Mounjaro users report losing 3 to 6 kg in the first month, though results vary based on starting weight, dose, and how closely dietary guidance is followed. The early weeks focus on dose adjustment and managing side effects rather than maximum weight loss.

Is it normal for weight loss to slow down after the first month?

Yes. A slowdown after the first month is completely normal. The body adapts to a lower calorie intake over time, which reduces the rate of loss. This is not a sign of failure and can be addressed by reviewing your diet, activity levels, and medication dose with your prescriber.

Do I still need to diet if I am taking Mounjaro?

Yes. Mounjaro reduces appetite and makes it easier to eat less, but it works best alongside a balanced, nutritious diet. Combining the medication with healthy food choices and regular activity produces significantly better and more sustainable results.
