About the clinic
Weight is rarely just about willpower
Hormones, metabolism, stress, sleep, medication and menopause can all affect your ability to lose weight and keep it off. Our private clinic offers a personalised, medically supervised approach led by Dr Karen Benson.
After a comprehensive assessment of your health, lifestyle and weight history, we build a treatment plan around your goals — which may include lifestyle support, metabolic testing and prescription medication where appropriate.
This is a private medical service and is not suitable for medical emergencies. If you need urgent care, seek immediate medical attention.
- Have struggled to lose or maintain weight
- Are considering, or already using, weight-loss medication
- Have weight-related conditions such as high blood pressure, prediabetes or PCOS
- Want to improve long-term metabolic health with expert medical support
Our approach
Beyond weight loss
Rapid weight loss without medical support can increase the risk of muscle loss, nutrient deficiencies and weight regain. Our aim is safe, sustainable results — not a quick fix.
"We combine medical expertise with practical lifestyle support to protect long-term health, not just this month's number on the scale."
Assessment
Full medical and lifestyle review, current medications, BMI and metabolic risk evaluation.
Treatments available
Not every treatment suits every patient
Weight-loss medicines can help, but they’re not right for everyone and shouldn’t be treated as a quick fix. All recommendations follow an individual consultation with Dr Karen Benson.
Mounjaro
Brand name for tirzepatide — a once-weekly injectable used for weight management in suitable adults, acting on gut-hormone pathways involved in appetite and blood-glucose regulation.
Wegovy
Brand name for semaglutide, a GLP-1 receptor agonist for weight management in suitable adults. Available as an injectable, with tablet options also emerging in the UK.
Lifestyle medicine
Medication is only one part of the picture. Food quality, protein intake, resistance training, sleep and stress remain the foundations of long-term success.
Continuous Glucose Monitoring
Reveals how your body responds to food, meal timing, stress, sleep and activity — useful for insulin resistance, PCOS, central weight gain or strong cravings.
Microbiome & Gut Health Testing
For patients with bloating, IBS-type symptoms or gut-health concerns, this may be considered as part of a broader assessment.

Frequently asked questions
Good to know before you book
Yes. These are prescription medicines and should only be used after a proper medical assessment, which helps confirm whether treatment is suitable and safe for you.
Where clinically appropriate, Dr Karen Benson can discuss these treatments. Suitability depends on your BMI, medical history, current medication, risk factors and goals.
All medicines can cause side effects. Common ones with GLP-1-based treatment include nausea, reflux, constipation, diarrhoea, abdominal discomfort and reduced appetite. Less common but more serious risks are why medical supervision matters.
Most people do, especially if the underlying drivers of weight gain haven’t been addressed. That’s why our approach includes nutrition, muscle maintenance, sleep, stress and a long-term maintenance plan.
No. The service looks at your wider metabolic health, lifestyle, appetite regulation, glucose response, gut health and medical background — not calorie counting alone.
Not everyone does — this depends on your medical history, medication, symptoms and risk factors.
Yes. Book a consultation to review your progress, side effects, dose, nutrition, muscle maintenance and long-term plan.
Yes. Perimenopause and menopause can affect body composition, appetite, sleep, mood, insulin sensitivity and fat distribution. Dr Karen Benson also provides menopause care and considers weight gain within that wider hormonal context.
For some patients, yes — it can help identify how your body responds to food, meal timing, sleep, stress and activity, particularly where insulin resistance or blood-sugar variability is suspected.
