How much weight have people lost on Wegovy — and what does that look like in practice?

The myth that a single number tells the whole story

When people ask how much weight others have lost on Wegovy, they often expect one clean answer. The reality is messier, and that is not a warning sign, it is just biology. The STEP 1 trial found an average reduction of around 15% of starting body weight over 68 weeks at the 2.4mg maintenance dose. But within that average, some participants lost considerably more and some lost less. Individual outcomes depend on factors the trial average cannot capture: the dose a person can tolerate, how quickly they titrate, what they eat, how active they are, and how their particular physiology responds to GLP-1 stimulation.

Newer data adds nuance. The recently approved 7.2mg semaglutide dose, cleared by the MHRA in April 2026, showed average weight loss of around 20.7% over 72 weeks in trials, closing the gap with tirzepatide and reframing what the ceiling looks like for semaglutide. If you are curious about how much weight people typically lose on Wegovy, from early weeks through to longer-term outcomes, our overview goes through those figures in detail. The short version: one number is never the complete picture.

The other misconception worth addressing early: Wegovy is not assessed by regulators for quick or cosmetic weight loss. The NICE recommendation for semaglutide (TA875) is grounded in clinical need, comorbidities, and structured lifestyle support alongside treatment. That framing matters when setting expectations.

What UK private pricing for Wegovy actually covers, and what it sometimes does not

Weight lost on Wegovy is one question. What it costs to get there is a separate one, and the two are connected: results in the trial came from consistent dosing over more than a year, which means the total cost of treatment is what matters, not just the first month's price.

UK private pricing for Wegovy is quoted per monthly supply and varies between providers and by dose. Since Eli Lilly raised Mounjaro's UK list price in September 2025, the wider GLP-1 private market has seen prices shift upward; semaglutide providers have broadly repriced in step. As widely reported, typical private prices for weight-loss injections now range roughly £149–£375 per month depending on medicine, dose, and provider. Those figures are real, but what sits underneath them varies considerably.

A headline monthly price from some providers is for the medicine alone. Consultation fees, prescription charges, delivery costs, and any clinical support between orders can all be billed separately. For a treatment you take every week for months, those additions compound. Our Wegovy price guide breaks down what a UK private prescription actually involves, start to finish, so the comparison you make is a fair one. There is also a separate question worth checking: whether any provider offering Wegovy vouchers or discount codes is operating through a GPhC-registered pharmacy, our page on Wegovy vouchers covers what those offers typically signal.

What nume's single price includes, and why we are not trying to be the cheapest

At nume, one price covers everything: the consultation, the prescription, the medicine, and free next-working-day delivery. Your order arrives in a plain, unmarked box via DPD (trackable on your phone from dispatch) and the pen inside is from the licensed UK supply chain, sourced through Novo Nordisk-authorised routes. There is no subscription, no auto-renewal, and no separate invoice for aftercare. A named prescriber re-reviews your case before every repeat order; the clinical oversight does not stop after the first pen.

We are not the cheapest option, and we do not try to be. The price reflects the safety infrastructure: photo-ID verification, live weight checks on video, Summary Care Record review where appropriate, and prescriber sign-off on every dose decision. A prescription medicine's cost is genuinely the wrong place to shave margins. The right question is not who charges least but whether the clinical review is real, the supply chain is verified, and the support continues through the months it takes to see meaningful results. You can check our pharmacy on the GPhC register (registration 9012878), that link goes directly to our entry.

For an honest side-by-side of what weight-loss treatment costs in the UK private market and what good value actually looks like, the treatment overview is the clearest place to start. Our about page sets out who we are and how the pharmacy is run, if that context is useful before you go further.

Why the cheapest option is the wrong metric for a prescription medicine

The MHRA has been direct on this. Fake weight-loss pens (some containing insulin rather than semaglutide) have been seized in large quantities across the UK, and some have reached patients who believed they were buying genuine medicine. The enforcement picture worsened through 2024 and 2025: around 20 million doses of illegally traded weight-loss medicines with an estimated £45 million street value were seized, and the first domestic manufacturing site producing counterfeit tirzepatide pens was raided in Northampton in October 2025.

Sellers offering GLP-1 medicines without a clinical consultation, through social media channels or with prices far below the market range, are the pattern to avoid. You can report any suspect seller at the MHRA Yellow Card portal, which also accepts reports of suspected side effects. A GPhC-registered pharmacy is verifiable by anyone, in under a minute, on the public register, that check costs nothing and removes most of the risk.

For context on how much weight people are losing on Wegovy week by week and month by month in practice, rather than as a trial average, that page covers real-world patterns in more detail. And if you want to understand how much weight can realistically be lost on Wegovy given your own starting point and circumstances, our weight loss treatment overview explains how prescribers think about individual suitability, including how much weight Wegovy may help you lose depending on your dose and duration of treatment.
