Still struggling to lose weight on Wegovy? Work through these questions first

Are you still on a starter dose, or have you reached maintenance?

This is the most common thing people miss, and it's worth saying plainly: the 0.25mg and 0.5mg doses of Wegovy are not designed to produce meaningful weight loss. They exist to let your body adjust to the medicine and reduce early nausea. The therapeutic work starts at higher doses, typically 1.7mg and 2.4mg, which is why the titration schedule takes several months to reach maintenance. If you started recently and aren't losing weight, the question isn't whether Wegovy works, it's whether you've had enough time at a sufficient dose for it to work.

The STEP 1 trial, published in the New England Journal of Medicine, followed participants at the full 2.4mg dose over 68 weeks and found an average weight reduction of around 15%. That trial didn't produce its headline results at week four on 0.25mg. If you're unsure where you sit on the schedule, that's a question for your prescriber rather than something to adjust yourself.

A plateau at 1.7mg or 2.4mg is different and worth a clinical conversation. If you've been on maintenance dose for three months or more and haven't seen at least 5% change from your starting weight, there are specific things worth reviewing with whoever manages your prescription.

What your eating pattern is actually doing during treatment

Wegovy reduces appetite reliably for most people, but appetite suppression isn't the same as calorie control, and this distinction matters more than people expect. A smaller appetite means you feel full sooner, but if the foods you eat when you do eat are very calorie-dense, or if your body has adapted its energy expenditure downward (a normal physiological response to weight loss), progress can slow even when the medicine is doing its job.

Protein intake, in particular, deserves attention on treatment. Adequately eating protein at each meal helps preserve lean muscle while losing fat, which in turn supports your resting metabolic rate. Fibre and hydration also play a role in how satisfied you feel between meals. None of this means you need a perfect diet (Wegovy is meant to make changes easier) but the medicine works with lifestyle changes, not instead of them. Practical adjustments that complement treatment are worth understanding before deciding the medicine isn't working.

Strength-based movement is often underestimated. Preserving muscle while losing weight helps avoid the metabolism slowdown that can make a plateau feel permanent. Even moderate resistance activity a couple of times a week can make a meaningful difference over several months of treatment.

When a plateau might signal something that needs clinical attention

Some stalls have nothing to do with dose or diet. Thyroid conditions, insulin resistance, certain medicines and disrupted sleep can all interfere with weight loss even when a GLP-1 medicine is on board. If you have any of these factors in play, a standard Wegovy schedule might need reviewing in the context of your broader health picture.

The NICE appraisal of semaglutide (TA875) recommends stopping treatment if less than 5% weight loss has been achieved after six months on the maintenance dose. That's a clinical threshold, not a judgment, and it points toward reconsidering whether a different approach might serve you better. For some people, that conversation opens a discussion about tirzepatide, which acts on two gut-hormone receptors rather than one and produced larger average results in the SURMOUNT-5 head-to-head trial. Your prescriber is the right person to weigh that up against your individual situation.

A useful starting point if you're uncertain is understanding the typical timeline of weight loss on Wegovy, so you have a realistic benchmark for where you should expect to be at your current stage of treatment.

What to do next

The decision in front of you is a clinical one, not a Google one. If you're struggling with weight loss on Wegovy and haven't yet had a thorough prescriber review, that's the first step. Changing your dose, switching medicines or stopping treatment should all be done with clinical input, the Patient Information Leaflet and your prescriber are the reference points for anything specific to your regimen.

There's a misconception worth gently laying down here: that struggling on Wegovy means you're not trying hard enough. Biology is more complicated than that, and a medicine that's right for one person at one stage isn't automatically the best fit at every stage. A good prescriber conversation looks at the full picture.

If you're considering starting treatment or reviewing your current prescription, understanding how Wegovy is legally prescribed and supplied in the UK is a sensible place to begin. You can also explore what weight-loss treatment options look like more broadly, or read about semaglutide as the medicine behind Wegovy.
