Consultation

When should you consider losing weight?

You may consider losing weight if it begins to affect your health, mobility, or confidence in daily life.

Medical professionals often use a tool called BMI (Body Mass Index) to understand whether a person’s weight is within a healthy range.

If your BMI is ≥ 30, or ≥ 27 with weight-related health problems you must consider losing weight.

How to check if you are in a healthy or overweight?

Your BMI is a quick calculation that compares your weight and height to estimate body fat levels.

You can use a simple online BMI calculator by entering your weight (in kilograms) and height (in metres).

• A BMI between 19.5 and 24.9 is considered healthy.
• A BMI between 25 and 29.9 is classed as overweight.
• A BMI of 30 or higher classifies obesity.

Note that BMI is a starting point, not a diagnosis. Learn more about treatment for obesity.

How to lose weight?

Safe weight loss is never rapid. It is a gradual progress. Healthy weight loss can be achieved by eating balanced meals, increasing physical activity, getting enough sleep, and managing stress, all of which contribute to steady, sustainable results.

For some people, lifestyle changes alone may not be enough to reach or maintain a healthy weight. In those cases, people may need to get additional medical support, such as prescription weight loss treatments, to complement diet and lifestyle.

Lifestyle changes to lose weight permanently

Long term results depend on habits that support your health every day. This includes choosing nutritious foods, staying active in ways you enjoy, drinking enough water, and limiting high-sugar or processed foods.

Sustainable change also means building a routine that feels achievable, like walking regularly, getting good sleep, and learning to listen to hunger and fullness cues. Consistency, not perfection, is what helps you maintain progress safely over time.

What you need to know about weight loss treatments

Weight loss treatments are designed to support, not replace, healthy habits. They work by helping to regulate appetite, improve how your body uses insulin, and support long-term weight management when used under clinical supervision.

Each prescription weight loss treatment begins with an online consultation form that evaluates your current overall health and medical history. Our UK-licensed prescribers review your provided health history, BMI, and any existing medical conditions. This helps determine whether a weight loss medication is suitable for you. Not everyone is eligible, and in some cases, lifestyle modifications alone may be more effective.

Weight loss treatments available at our clinic include: Mounjaro (tirzepatide) and Wegovy (semaglutide). We previously issued Saxenda (liraglutide) for weight loss, but due to unavailability of sexanda weight loss treatment in the UK, many patients switched to Wegovy or Mounjaro as an more effective alternative.

What are weight loss injections?

Weight loss injections have emerged as an important clinical option for managing obesity or unhealthy weight gain. Weight loss injections provide a non-surgical, medically supervised way to support appetite regulation and gradual weight reduction.

Their growing use in the UK and internationally reflects both strong scientific evidence and a broader recognition of obesity as a medical condition rather than a personal choice. The accessibility of regulated online consultations has also made it easier for eligible patients to receive professional guidance and prescribed treatments safely.

By helping to improve metabolic health and support sustainable weight management, these injections can play a valuable role in achieving long-term well-being when combined with healthy lifestyle changes.

Medications licensed for weight loss include Mounjaro, Wegovy, and Saxenda, all designed to be used alongside a balanced diet and regular physical activity. For best results, prescription weight loss injections should form part of a comprehensive, clinician-guided plan focused on nutrition, movement, and behaviour change.

Clinical studies have shown that, when used as prescribed and supported by lifestyle changes, these treatments can lead to an average weight reduction of around 10 – 20% of initial body weight. However, the actual results may vary from person to person, considering everybody has different tolerance levels and may respond differently to medications.

What are GLP-1 medications?

Mounjaro (tirzepatide), Wegovy (semaglutide), and Saxenda (liraglutide) are all GLP-1 medications. That means these weight loss injections work by mimicking a natural hormone called glucagon-like peptide-1 (GLP-1), which helps regulate appetite and blood sugar levels.

When injected, these medications slow down digestion, helping you feel full for longer and reducing overall food intake.

They also help the body use insulin more effectively, supporting balanced energy levels throughout the day. Over time, this combination of effects can lead to a gradual decrease in body weight when combined with lifestyle changes like healthy eating and regular exercise.

The process must be monitored carefully to ensure safety, correct dosage, and clinical effectiveness.

How do weight loss injections work?

Weight loss injections work by imitating a natural hormone in the body called GLP-1 (glucagon-like peptide-1). This hormone plays a vital role in controlling appetite, digestion, and blood sugar levels.

When injected, GLP-1 medications such as Wegovy, Mounjaro, and Saxenda help slow the rate at which the stomach empties, allowing you to feel fuller for longer and reducing the urge to overeat. They also help the body use insulin more effectively, which supports better energy balance and metabolic health.

Most treatments are taken once a week (for Wegovy or Mounjaro) or once daily (for Saxenda), depending on the medication prescribed. These injections come in different doses that are gradually adjusted to ensure comfort and safety as your body adapts.

Clinical expectations should always be realistic and focused on overall well-being, not instant results. The best outcomes are achieved when these treatments are combined with healthy eating, regular physical activity, and ongoing clinical supervision.

Do I qualify for weight loss injections?

Eligibility for weight loss injections depends on your BMI, health background, and individual needs.

Generally, these treatments may be prescribed for adults who:

• Have a BMI of ≥ 30.
• Have a BMI of ≥ 27 with a weight-related health condition (such as type 2 diabetes, high cholesterol, or hypertension).

Note:

This is a general eligibility criterion. Each weight loss injection follows a different set of eligibility criteria based on BMI. These medications cannot be used in those who are pregnant, planning a pregnancy or breastfeeding.

Your eligibility for weight loss injections may only be determined after you fill out our online consultation form. This is needed to assess your overall health and verify if your medical information and medical history fall under the set criteria.

Weight loss injections vs weight loss pills

Both weight loss injections and oral medications are prescribed to support safe weight management, but they work in different ways.

Weight loss injections, such as GLP-1 medications (e.g., Wegovy or Mounjaro), act on appetite-regulating hormones in the body. They help you feel fuller for longer, reduce hunger, and support better blood sugar balance. These treatments are often recommended for individuals with a higher BMI or for those who have found lifestyle changes alone difficult to maintain.

Oral medications, such as appetite suppressants or fat absorption blockers, work differently. They target metabolism or nutrient absorption and may be suitable for people looking for a shorter-term or milder medical option, when appropriate. The most suitable approach depends on your BMI, medical history, and health goals. A UK-registered clinician will review your health background and guide you toward the safest, most effective plan for your circumstances.

Regardless of the treatment chosen, medications should always be used alongside balanced nutrition, physical activity, and ongoing clinical support and never as a replacement for healthy habits.

At London Slimming Clinic, every consultation is individually reviewed to ensure the treatment aligns with your medical needs and supports your overall well-being.

Weight loss injections side effects

Like any prescribed medication, weight loss injections can cause side effects, although not everyone experiences them.

Common side effects may include:

• Mild nausea
• Constipation or diarrhoea
• Stomach discomfort
• Fatigue or headache

These symptoms are often temporary and improve as your body adjusts to the medication.

In rare cases, more serious side effects may occur. That’s why all patients are advised to refer to the weight loss treatment side effects available in the patient information leaflets for Mounjaro and Wegovy.

Which weight loss treatment is right for me?

Choosing the right treatment depends entirely on your individual health profile. Factors such as BMI, existing medical conditions, lifestyle, and previous treatments all play a role in determining what is safe and suitable for you.

Both Mounjaro (tirzepatide) and Wegovy (semaglutide) are MHRA-approved and licensed in the UK for weight management. The main difference lies in their active ingredients and dosage frequency.

Because no two individuals experience obesity in the same way, what works best for one person may not be suitable for another. It’s essential to have a consultation with a UK-registered healthcare professional to discuss your symptoms, medical history, and treatment goals in detail.

Where to get weight loss injections in the UK?

Weight loss injections should only be obtained through a UK-registered pharmacy following a clinician-approved prescription.

At London Slimming Clinic, we make the process simple, secure, and entirely regulated, ensuring every treatment is dispensed safely by our GPhC-registered pharmacy.

Long-term weight loss maintenance

The goal of weight management isn’t only to lose weight, it’s to reach a healthy weight for your body and maintain it safely. Sustainable results come from building habits you can keep up, rather than relying on short-term fixes.

After completing a prescribed treatment, it’s important to continue making small, realistic changes to your daily routine. Eating balanced meals, staying active, managing stress, and getting enough rest all play a big part in helping you maintain your progress.

Sometimes, your clinician may review your progress and suggest whether continuing medication or exploring other forms of support would be helpful.

Try to focus on changes that fit your lifestyle, walk more often, take the stairs, or find an activity you enjoy doing regularly. Aim for more whole foods, like fruits, vegetables, lean proteins, and wholegrains, and enjoy treats in moderation.

Avoid fad diets that promise quick results; they can cause your weight to fluctuate and make long-term maintenance harder. Consistency, not perfection, is what leads to lasting health.

Conclusion

Every treatment works best when combined with balanced nutrition, regular physical activity, and ongoing clinical guidance. At London Slimming Clinic, all online consultation forms are assessed by UK-registered weight loss specialists and dispensed safely and confidentially, ensuring the highest standards of care, safety, and privacy.
