How much protein do you need on Wegovy — and what does good support cost?

Why protein matters more when your appetite is smaller

One of the most common misconceptions about Wegovy is that eating less is, by itself, the goal. It isn't. The medicine reduces appetite so that eating less becomes manageable, but the body still needs enough protein to hold on to muscle while fat is lost. When overall calories fall sharply, muscle can go with them if protein is inadequate, which tends to slow metabolism and make it harder to keep weight off long term.

The practical guidance from dietitians and the broader clinical literature points toward roughly 1.2g to 1.6g of protein per kilogram of body weight daily for someone losing weight actively. For a 90kg person that works out to roughly 108–144g of protein each day, spread across meals. If you want to understand how much protein you need on Wegovy and why those figures are set where they are, the detail is worth reading before you adjust your meals. Because Wegovy slows gastric emptying, some people find large meals harder to tolerate; eating protein earlier in a meal (before appetite fades) is a small habit that pays off, and our page on how much protein to aim for while on Wegovy explores how to fit that into everyday eating. For a fuller breakdown of how to hit those targets on reduced portions, our guide to protein choices on Wegovy covers practical food sources and portion ideas. If you prefer a straightforward number to work from, our page on how much protein per day on Wegovy translates the ranges into daily gram targets by body weight, and for personalised guidance our page on how much protein you should eat on Wegovy walks through the factors that shift the recommendation up or down for different people.

None of this replaces a conversation with your prescriber or a dietitian. Personal targets depend on kidney function, activity level, and starting composition, all things a clinical review should capture.

What private Wegovy treatment actually costs in the UK

UK private pricing for semaglutide varies between providers and by dose. Headline prices are typically quoted per pen or per four-week supply, and they have shifted as the market has matured. Eli Lilly's September 2025 list-price increase for tirzepatide (Mounjaro) pushed comparison shopping further into the spotlight; Wegovy pricing from private providers typically ranges from roughly £149 to over £300 per month depending on the dose and supplier, though these figures move and should be treated as indicative. For a current sense of the private market, our Wegovy price guide sets out what drives cost at each dose level.

What headline prices often leave out is everything that wraps around the medicine itself: the initial consultation fee, the prescription fee, delivery charges, and any aftercare or dose-review support. A low per-pen price with a separate consultation charge and a delivery fee can quietly become more expensive than it first appears. It is also worth reading whether any quoted price covers a clinical re-review before each repeat, or whether repeat orders are processed with minimal clinical oversight.

Checking whether any online pharmacy is properly registered takes about thirty seconds. The GPhC register entry for our pharmacy is publicly searchable; every legitimate UK online pharmacy should have an equivalent listing you can verify.

What the nume price includes, and what we are upfront about

At nume, we are not the cheapest option in this market, and we have made that choice deliberately. One price covers the consultation, the prescription, the medicine, and free next-working-day delivery by DPD. There are no bolt-on fees and no subscription pulling a payment from your account next month without a fresh clinical review. Every repeat order is assessed by a GPhC-registered prescriber before it goes out. Our about us page sets out how the service is structured, and our clinical team page introduces the prescribers who sign off each consultation.

Nutritional guidance (including protein targets) is part of the aftercare conversation, not an upsell. If questions come up between orders, our prescribers are available seven days a week. You can also read through common questions about the service before you start. For anyone comparing providers, our Wegovy price comparison overview sets out the questions worth asking of any provider, including what is and is not included in their quoted price.

Why price alone is the wrong measure for a prescription medicine

Wegovy is a Prescription-Only Medicine. That legal status exists because semaglutide carries real clinical considerations (pancreatitis risk, gastrointestinal side effects, contraindications in certain conditions, interactions with how oral medicines are absorbed) that require proper assessment. The MHRA has warned on multiple occasions about fake weight-loss pens sold online, and in October 2025 enforcement teams raided a UK site manufacturing counterfeit tirzepatide; the pattern of fake pens appearing across social-media marketplaces is well documented. Sellers offering these medicines without a proper prescription or clinical assessment are a red flag, not a bargain. Report any suspect sellers via the MHRA's Yellow Card scheme.

For a Prescription-Only Medicine, the cheapest listing answers the wrong question. Clinical rigour, verified supply chains, genuine prescriber oversight, and a service you can actually reach if something goes wrong, those are the criteria that protect you. Our weight loss treatment overview covers all the options we prescribe and how we approach each one. If you are ready to take the next step, start your free consultation and a prescriber will review your details the same day.
