How Much Weight Can You Lose on Wegovy in 6 Months?

The honest answer: where most people land at the halfway point

Six months in, most people on Wegovy are still titrating or have recently reached their maintenance dose. The standard schedule moves from 0.25mg up through 0.5mg, 1mg and 1.7mg before arriving at 2.4mg, a process that takes roughly 16 weeks. That means at the six-month mark, some patients have been at full dose for only a matter of weeks, while others have been there for three months or more. Timing matters a great deal to the numbers.

In clinical trials, weight loss continued to accumulate throughout the first year and beyond. At three months, average losses tend to sit in the 5–8% range, and understanding exactly how much you can lose on Wegovy in those first three months helps set a realistic baseline before the six-month picture comes into view; by six months, that typically rises to 8–15%; by 68 weeks (the end of the STEP 1 trial), the average reached around 15%. A smaller group achieved considerably more. So if you're six months in and have lost 10%, that's a clinically meaningful result, and there's often more to come.

It's also worth knowing that the NICE appraisal of semaglutide (TA875) uses 5% weight loss after six months as the clinical threshold for deciding whether to continue, which tells you that measurable progress by this point is both expected and used as a real decision point in practice.

The factors that actually shape how much you lose

Two people on the same dose of Wegovy for the same six months can see quite different results. That isn't a flaw in the medicine, it reflects real variation in biology, behaviour and circumstances. The factors our prescribers discuss most often include:

Starting weight and body composition matter because a larger absolute loss can accompany a smaller percentage, and vice versa. Metabolic rate, insulin sensitivity and underlying conditions all influence how the body responds to reduced appetite. How much you can expect to lose in a single month on Wegovy is something many patients ask about early in treatment, and it depends considerably on which stage of titration you're at. What you eat during treatment plays a significant role too, Wegovy reduces hunger but doesn't override dietary choices entirely; protein adequacy and fibre intake both support the medicine's effect. Exercise, particularly strength training, helps preserve muscle as weight falls. And adherence to the dose schedule is simply fundamental: missed injections slow titration and blunt results.

Dose tolerance also varies. Some people reach 2.4mg smoothly; others spend longer at an intermediate dose because of gastrointestinal side effects. That's a clinical decision made with your prescriber, not something to push through alone. If you'd like a clearer picture of how much you can realistically lose on Wegovy overall, our guide covers the full evidence base.

What the price of six months on Wegovy actually includes, and what it often doesn't

UK private Wegovy pricing is quoted per month or per pen, and it varies between providers. Since Eli Lilly's September 2025 list-price revision for Mounjaro set a new market reference point, private semaglutide pricing has broadly ranged from around £149 to £250 per month depending on dose and provider, though these figures are hedged, they're reported, not guaranteed, and the market moves. The full breakdown of Wegovy pricing in the UK sets out what to expect at each dose.

The more important question is what a headline monthly price includes. Many quoted figures cover the medicine only. Add a consultation fee, a prescription charge, a delivery fee, and ongoing clinical support, and the real cost of six months' treatment can look quite different from the advertised figure. Checking this before you commit is straightforward: ask whether the consultation is free, whether prescriptions are included, whether delivery is charged per order, and whether aftercare is available if you hit a problem.

At nume, we're not going to be the cheapest option you find, that's a deliberate choice. One transparent price covers your consultation, prescription, treatment and free next-working-day tracked delivery, with aftercare available seven days a week and clinical re-review before every repeat. No add-on fees surface later. Our clinical team reviews every consultation personally before any prescription is issued. You can verify our GPhC-registered pharmacy at any point using registration number 9012878 on the GPhC pharmacy register.

If you order before midday on a weekday, an approved prescription is dispatched the same day and arrives the next working day via DPD, plain, unbranded packaging, tracked on your phone. Worth knowing if you're planning around a busy week.

Why 'cheapest' is the wrong measure for a prescription medicine

Wegovy is a Prescription-Only Medicine. UK law requires a prescription following clinical assessment, any seller offering it without one is operating outside the law. The MHRA has warned repeatedly about counterfeit and illegally traded weight-loss pens; in 2025 alone, around 20 million doses of illegally traded weight-loss medicines (roughly £45m street value) were seized, and a site producing fake tirzepatide pens was raided in Northampton. Fake pens have in some cases contained insulin rather than the stated medicine.

Red flags include prices dramatically below the market range, sellers operating through social media, and any claim that no clinical assessment is required. If you're uncertain about a provider, check whether they're listed on the GPhC register before handing over any personal or payment details. You can also report suspect sellers via the MHRA's Yellow Card scheme.

For a medicine that requires titration, ongoing monitoring and clinical judgement at each stage, the question isn't which provider quotes the lowest number. The question is which service will keep you safe, notice problems early and support you through six months of treatment properly. That's what a good clinical consultation (like the one available at nume's free consultation page) is designed to do. Exploring your treatment options first is always a reasonable place to start.
