    The Treatment

    Metabolic & Weight Optimisation

    Metabolic & Weight Optimisation at 23MD is a structured medical programme designed to address body composition, metabolic health, and the underlying drivers of weight gain, not a single prescription. Depending on your individual assessment, the programme may include bloodwork-led lifestyle support, BHRT and, where clinically appropriate, prescription treatment discussed at consultation.

    Prescription treatment, where clinically appropriate, is not a strategy on its own. Patients who do well long-term are the ones who use the medication within a structured programme, protecting lean mass, optimising hormones, addressing the lifestyle drivers of weight gain, and planning carefully for what happens when the medication is reduced or stopped. The medication is one tool. The plan is the treatment.

    About

    What it is, how it works.

    How it works

    The programme begins with a comprehensive medical consultation, full bloodwork, and a body-composition assessment. From there, your doctor builds a plan around the tools most appropriate to your physiology, goals, and risk profile. GLP-1 medications, where appropriate, are prescribed and monitored within the programme, not as a standalone treatment. Hormones and lifestyle support are layered in where they add clinical value.

    Why it matters

    Prescription treatment, where clinically appropriate, is not a strategy on its own. Patients who do well long-term are the ones who use the medication within a structured programme, protecting lean mass, optimising hormones, addressing the lifestyle drivers of weight gain, and planning carefully for what happens when the medication is reduced or stopped. The medication is one tool. The plan is the treatment.

    FAQs

    Your Questions, Answered

    A structured medical programme covering body composition, metabolic health, and weight, combining the right tools (GLP-1 medications, BHRT, and lifestyle support) within a doctor-led plan.

    Where clinically appropriate, your doctor will discuss prescription options with you at consultation, alongside lifestyle and hormonal support.

    Many of our patients come to us after starting GLP-1 medications without a wider plan. We can take over and integrate the medication into a structured programme.

    Typically an active phase of 3–12 months, followed by a structured maintenance and step-down plan.

    Long-term outcomes depend significantly on the maintenance plan and continued engagement. The programme is specifically designed to address what happens when the active medication phase ends.

    When prescribed and monitored within a doctor-led medical programme, GLP-1 medications are supported by a substantial body of clinical evidence in suitable patients.

    Hormones are central to body composition, particularly in peri/post-menopausal and andropausal patients. BHRT is often integrated where clinically relevant.

    Lean mass preservation is a core part of how we design the programme, through hormonal support, body-shaping devices, and structured guidance.
