For too long, the conversation around weight loss has been one-size-fits-all. Yet, men’s bodies, metabolisms, and health challenges are unique.

At HeMed, we understand this. We’ve developed a comprehensive weight loss programme designed specifically for men, combining cutting-edge medical science with personalised, real-world support. Mounjaro (tirzepatide) is one of the licensed treatments available through the programme.

It’s a dual-action treatment that works with your body’s natural systems to regulate appetite and blood sugar, leading to significant and sustainable weight loss. When combined with the expert guidance, tailored nutrition, and fitness coaching of the HeMed programme, it represents a powerful new chapter in men’s health. This page will explain exactly how Mounjaro works, how the HeMed programme supports your journey, and how this combined approach, fully aligned with MHRA regulations (the MHRA is the UK medicines regulator), can help you finally take control of your weight and transform your health.

Understanding Mounjaro and how it works

Mounjaro, the brand name for the medication tirzepatide, represents a significant advancement in weight management. It is the first in a new class of medicines known as dual GIP and GLP-1 receptor agonists (medicines that mimic two naturally occurring gut hormones).

But what does that mean for you? In simple terms, Mounjaro works by mimicking the effects of two naturally occurring hormones in your body that are crucial for managing hunger and blood sugar.

The science of satiety: GIP and GLP-1

Your gut produces hormones that signal to your brain when you’re full and help control how your body processes food and sugar. The two key hormones Mounjaro targets are:

GLP-1 (Glucagon-like peptide-1): This hormone is released after you eat. It helps to lower blood sugar levels by stimulating insulin release, slows down the speed at which your stomach empties (making you feel fuller for longer). It acts on the appetite centres in your brain to reduce hunger and cravings.
GIP (Glucose-dependent insulinotropic polypeptide): This hormone also plays a role in managing blood sugar. It has been shown to decrease food intake and improve how the body breaks down sugar and fat.

Mounjaro is unique because it activates the receptors for both of these hormones. This dual-action mechanism is believed to be more effective for weight loss and blood sugar control than medications that only target the GLP-1 receptor. By enhancing these natural bodily signals, Mounjaro helps you feel satisfied with smaller portions, reduces persistent food cravings, and improves your body’s metabolic health.

What the clinical trials showed

The effectiveness of Mounjaro is not just theoretical; it’s backed by extensive clinical research. The SURMOUNT-1 trial, published in the New England Journal of Medicine, reported the following. In this study, participants taking tirzepatide for weight management (without type 2 diabetes) achieved substantial and sustained weight loss over 72 weeks.

Key findings showed that participants on the highest dose of Mounjaro lost an average of nearly 21% of their body weight.

In the UK, the National Institute for Health and Care Excellence (NICE) has recognised this potential. In Technology Appraisal Guidance TA1026 (23 December 2024), NICE recommends tirzepatide as an option for managing overweight and obesity in adults, alongside a reduced-calorie diet and increased physical activity, within its eligibility criteria.

How is Mounjaro administered?

Mounjaro is a prescription-only medication administered as a once-weekly injection. It comes in a user-friendly, pre-filled pen, making the process simple and convenient. The injection is subcutaneous, meaning it goes just under the skin of your abdomen, thigh, or upper arm.

Your HeMed clinical team will provide comprehensive training and support to ensure you are comfortable and confident with the administration process. The dosage typically starts low and is gradually increased by your doctor to minimise potential side effects and find the most effective dose for you.

It is crucial to remember that Mounjaro is not a cosmetic solution. It is a powerful medical treatment that requires a full consultation and prescription from a qualified healthcare professional.

The HeMed programme: a tailored approach to men’s weight loss

Medication alone is only part of the solution. Sustainable weight loss requires a holistic approach that addresses nutrition, physical activity, and the psychological aspects of health.

This is where the HeMed programme provides the essential framework for your success. We don’t just give you a prescription; we give you a plan, a team, and the unwavering support you need to build lasting healthy habits.

The programme is built around men’s health:

Personalised Clinical Supervision: Every plan starts with an at-home blood test and a clinician review. Our clinicians will assess your health history and determine if Mounjaro is a safe and appropriate option for you. Throughout the programme, you’ll have regular check-ins to monitor your progress, manage any side effects, and adjust your treatment plan as needed.

Continuous Progress Tracking and Support: We use technology to help you stay on track, but our support is deeply human. Through our app and regular consultations, we monitor your progress, celebrate your milestones, and provide the motivation and accountability needed to navigate challenges. You are not alone on this journey; the entire HeMed team is behind you.

How Mounjaro and the HeMed programme work together

Mounjaro works on a physiological level to reset your body’s relationship with food. By reducing your appetite and cravings, it breaks the cycle of overeating and gives you the headspace to make conscious, healthier choices. It creates the biological opportunity for change.

The HeMed programme provides the structure, knowledge, and support to seize that opportunity. We teach you what to eat, how to move, and why it matters, empowering you to build habits that will last long after you’ve reached your goal weight.

More than just weight loss

The benefits of this combined approach extend far beyond the number on the scales. For men, carrying excess weight, particularly around the abdomen, is linked to a host of serious health issues. By achieving significant weight loss, you can:

Improve Cardiovascular Health: Reduce blood pressure, lower cholesterol levels, and decrease your risk of heart attack and stroke.
Reduce the Risk of Type 2 Diabetes: Mounjaro is also licensed for type 2 diabetes, and weight loss is one of the most critical factors in preventing or even reversing type 2 diabetes.
Boost Energy and Vitality: Shedding excess weight can lead to a dramatic increase in energy levels, reduced joint pain, and improved mobility.
Enhance Mental Well-being: The journey of taking back control of your health is incredibly empowering.
Support Hormonal Health: Excess body fat can negatively impact testosterone levels. Weight loss can help restore a healthier hormonal balance.

Mounjaro: considerations and safety information

Patient safety is our absolute priority. Mounjaro is a highly effective medication, but it is not suitable for everyone. A thorough medical evaluation with a HeMed clinician is essential to determine your eligibility.

Potential side effects

Like all medications, Mounjaro can cause side effects. The most common are gastrointestinal and are usually mild to moderate, often decreasing over time as your body adjusts. These can include:

Nausea
Diarrhoea
Decreased appetite
Vomiting
Constipation
Indigestion or abdominal pain

Our clinical team will guide you on how to manage these potential side effects, and the gradual dose-increase schedule is designed to minimise them.

Important safety information

Mounjaro is not suitable for individuals with certain medical conditions. Mounjaro is not suitable in pregnancy or when trying to conceive, under 18, or with certain medical histories: the clinician screens for these, and the patient information leaflet carries the full list.

Before starting treatment, you must provide your doctor with a complete medical history, including all existing conditions and any other medications you are taking (including over-the-counter supplements).

The Medicines and Healthcare products Regulatory Agency (MHRA) is responsible for ensuring that medicines in the UK work and are acceptably safe. You can find the official Patient Information Leaflet and further safety details on the MHRA Products website. Our clinical team adheres strictly to all MHRA and NICE guidelines to ensure your treatment is both safe and effective.
