Medically Supervised Weight Management-What a Properly Run GLP-1 Programme Actually Involves, and What It Costs
Aug 2026
GLP-1 medications have changed what is possible for weight management, and they have also created a genuine problem: a prescription handed over after a five-minute online questionnaire, with no baseline bloods, no examination and no ongoing clinical oversight, is not the same medical proposition as the same drug prescribed and monitored properly. The Wellness runs medically supervised weight management from a £450 baseline assessment through to a £4,995 annual programme combining prescribing, continuous glucose monitoring, quarterly bloods and ongoing physician oversight for the full duration of treatment. Fees for every level appear further down this page.

Why a prescription alone is not a weight management programme
GLP-1 medications work by suppressing appetite and slowing digestion, and for the right person, properly assessed, they can be genuinely transformative. But the drug is only one part of what actually determines the outcome. A proper assessment before starting treatment establishes baseline bloods including HbA1c, liver and kidney function and a full lipid profile, rules out thyroid disease and other conditions that can present as weight gain, and takes a genuine history of eating patterns, previous attempts and any relevant family or personal history that changes the risk-benefit calculation. None of that happens in a questionnaire-only online model, which is exactly why the fastest, cheapest-looking route to a prescription is so often the one that skips the parts of the process that actually keep treatment safe and effective.
What proper monitoring during treatment actually catches
Muscle loss alongside fat loss is one of the most under-discussed risks of rapid weight loss on these medications, and body composition tracking, rather than relying on the scale alone, is what actually shows whether the weight coming off is the weight you want to lose. Dose titration matters enormously too, since the right starting dose and the pace of increase varies by individual, and doing this without clinical oversight is how side effects, particularly gastrointestinal ones, end up more severe than they need to be. Ongoing bloods through treatment catch nutritional deficiencies before they become a problem, and a doctor who sees you regularly is the one who notices early if the weight loss is plateauing, if side effects are becoming genuinely difficult to tolerate, or if the dose needs adjusting in either direction. Continuous glucose monitoring, in the same way we cover in our guide to metabolic health screening, adds a further layer of insight into exactly how your own metabolism is responding, which a scale alone cannot show.

What happens when treatment stops
A significant proportion of people regain weight after stopping GLP-1 treatment if nothing else has changed in the meantime, which is precisely why a properly run programme treats the medication as part of a plan rather than the whole plan. Building genuine changes to eating patterns and activity alongside the medication, rather than relying on appetite suppression alone to do all the work, is what determines whether the result holds once treatment ends or tapers. This is exactly the conversation that a rushed online prescription model has no time or structure to have, and it is the single biggest predictor of whether this investment holds its value over years rather than months.
What it costs in London
Online prescription-only services can appear considerably cheaper on a monthly basis because the price reflects medication and little else, no baseline assessment, no ongoing bloods, no body composition tracking, and minimal or no access to a doctor between renewals. That gap is where the real cost of an inadequately supervised programme tends to surface later, whether through a missed underlying condition, more severe side effects than necessary, or weight regained once the cheapest option's minimal support runs out.
At The Wellness, all figures are from prices.
Weight Management Baseline — full baseline bloods, examination, body composition analysis and a personalised assessment with a doctor, from £450.
GLP-1 Medically Supervised Programme — the above plus prescribing, dose titration and monthly clinician review for three months, from £1,650.
Comprehensive Weight and Metabolic Programme — the above plus continuous glucose monitoring, quarterly bloods, body composition tracking and 12 months of ongoing physician oversight through treatment and beyond, from £4,995 per year.
Assessments are held in Marylebone, three minutes from Baker Street, with appointments available within the week.
Why The Wellness is the right clinic for this
Because a prescription is the easy part, and the value sits entirely in the assessment before it and the monitoring throughout it. Every programme here starts with proper baseline testing and a genuine conversation about history and goals, dose changes are made by a doctor watching your actual response rather than a fixed schedule, and because The Wellness is a full clinic, anything that needs addressing along the way, from a nutritional deficiency to a plateau that needs a change in approach, is managed by the same team rather than left for you to work out alone.
Frequently asked questions
Do I need blood tests before starting a GLP-1 medication?
Yes. A proper baseline includes HbA1c, liver and kidney function, thyroid and a full lipid profile, both to confirm the medication is appropriate for you and to give a reference point for monitoring through treatment.
Will I lose muscle as well as fat?
Rapid weight loss can include muscle loss if not managed properly, which is why body composition tracking and adequate protein intake are built into a properly supervised programme rather than left to chance.
What happens if I stop the medication?
Weight regain is common if nothing else has changed, which is why a proper programme focuses on building sustainable habits alongside the medication rather than treating the drug as the entire solution.
Is a cheaper online prescription service just as good?
It provides the medication, but typically without baseline testing, ongoing bloods, body composition tracking or meaningful access to a doctor between renewals, which is exactly where problems tend to surface later rather than immediately.
Do I need a referral to start?
No. You can book directly, and a doctor reviews your history and confirms whether treatment is appropriate before anything is prescribed.
