Our weight loss treatments & plans

We assess every patient’s individual medical history to determine which weight loss options are suitable. Here are some of the treatments that may be available to you.

Mounjaro

Mounjaro is a weekly self-injectable pen used for weight loss. It contains tirzepatide, which can regulate blood sugar and balance energy levels, helping to reduce appetite and prevent cravings. Mounjaro is designed to be used alongside a healthy diet and regular exercise, helping you form long-term habits that lead to sustained weight loss.

Wegovy

Wegovy is a weekly self-injection pen for weight loss. It contains semaglutide, a medication that helps control appetite and reduce food cravings. Wegovy can help achieve sustained weight loss when used alongside healthy lifestyle habits. Semaglutide may also reduce the risk of cardiovascular problems like heart attack in some adults.

“Our goal is to combine precision diagnostics with lifestyle medicine to preserve muscle and support sustainable improvements in metabolic health, rather than pursuing extreme calorie restriction.”

Education & Accreditations

A clinical & personalised approach to weight loss

Achieving and maintaining a healthy weight can feel complex, particularly if underlying health factors are working against you. Many patients struggle not because of motivation, but because the true drivers of weight gain are never properly identified.



At Harley Weight Loss Clinic, operating within Harley Street Specialist Hospital, programmes are overseen by our medical director Dr Saima Ajaz, a specialist in metabolic health, preventive medicine, and advanced diagnostics. Her approach is data-led and whole-body focused, ensuring each plan is built around clinical insight and individual health data rather than generic weight loss advice.



Rather than applying standardised programmes, we focus on understanding the individual factors influencing weight, including metabolism, body composition, lifestyle, and underlying health markers. Patients may undergo blood work and diagnostic assessment to uncover hidden contributors to weight challenges, with advanced diagnostics used when clinically indicated.



This ensures decisions are guided by objective findings and aligned with long-term health rather than short-term results. Dr Ajaz highlights the importance of protecting muscle mass and metabolic health during weight loss, reinforcing the need for structured programmes and supportive clinical supervision.



Your programme is medically supervised and designed to evolve as your health improves, with ongoing review to ensure progress remains safe, effective, and sustainable.

Reclaim your body positivity

Millions of people struggle to manage their weight, so if you’re looking for weight loss support, you’re not alone. Being overweight can result in physical health problems, as well as contributing to feelings of poor self-image and low confidence.



That’s why many people are turning to our weight management programmes. Our plans help you break bad habits and create new, healthier behaviours that contribute to overall wellbeing. Through a combination of coaching, medical therapy, diagnostic tests, and nutritional guidance, we provide weight loss programmes that help you feel more energised and confident.



Effective weight loss programmes take a holistic approach, emphasising the importance of diet, caloric balance, and exercise alongside adjunct treatments. Building these lifestyle changes into your programme creates long-term habits that will help you maintain your progress — even after you stop using medical treatments.

The most successful weight loss programmes are those that fit easily into your lifestyle. All Harley Weight Loss Clinic plans are designed to help you lose weight in a realistic, sustainable way. It’s why so many patients opt for our transformative doctor-led approach to weight loss.
