About Mayfair Weight Loss Clinic
Mayfair Weight Loss Clinic prescribes and delivers clinically guided weight-management services focused on safety, suitability, and sustainable outcomes. All services are assessed by a UK-licensed clinical team and tailored to individual health needs through a structured, medical-led process.
Our focus is not short-term weight change, but responsible, long-term weight management supported by clinical judgement and evidence-based care. Every patient's journey begins with a medical consultation to determine whether treatment options are appropriate, ensuring decisions are made based on health considerations rather than convenience.

Our Clinical Approach
At Mayfair Weight Loss Clinic, weight management is treated as a medical condition influenced by lifestyle, health history, and individual circumstances. It requires careful evaluation and ongoing professional oversight.
Before any treatment pathway is considered, our clinical team review each patient’s medical background, current health status, and personal goals. Where treatment is clinically appropriate, recommendations are designed to support healthy lifestyle changes alongside structured clinical guidance.
We do not offer standardised solutions. Instead, our approach is built around:
- Clinical safety and eligibility
- Individual health needs
- Ongoing monitoring and support
- Clear, informed patient choice
