Still losing weight on 2.4mg Wegovy — what to expect at the maintenance dose

You've reached 2.4mg and the scales feel stuck, here's what's happening

Picture this: you've spent the best part of five months stepping up through 0.25mg, 0.5mg, 1mg and 1.7mg, and you've just taken your first 2.4mg pen. The nausea has settled down. You're eating less without really trying. But the number on the scales, which was shifting steadily a few months ago, now seems to move only a little each week, or barely at all some weeks.

This is one of the most common points at which people wonder whether 2.4mg is actually doing anything. It is. What's changed is the phase of weight loss, not the medicine's activity. Early in treatment, the appetite suppression effect is newest and the calorie deficit tends to be sharpest, and if you're curious whether results are possible right from the start, many people do see changes even at the 0.25mg starting dose. By the time you reach 2.4mg, your body has also adapted, resting metabolism adjusts as body weight falls, which is a biological response that happens with any significant weight loss, not a Wegovy-specific one. The result is that a smaller deficit produces slower, steadier loss rather than the faster drops of the first few months. According to the STEP 1 trial in the New England Journal of Medicine, weight loss continued throughout the 68-week study period, with around 15% average reduction by the end, a figure that took the full treatment course to accumulate.

Patience at this point is genuinely worth it. A slower rate of loss on 2.4mg is expected, and it compounds.

What 2.4mg is doing in the background, even when the scales are quiet

Semaglutide works as a GLP-1 receptor agonist, mimicking a gut hormone that signals fullness to the brain and slows the rate at which the stomach empties. At 2.4mg (the highest licensed dose for weight management in the UK) both of those effects are at their maximum. You're less hungry, food moves more slowly through your system, and meals feel satisfying with less food eaten.

What that means practically is that even on a week when you don't lose weight on the scales, your body may be recomposing, losing fat while retaining muscle, or releasing fluid while gaining a small amount elsewhere. The scales are a rough instrument. Waist measurements, how clothes fit, and energy levels often tell a more complete story during this phase.

It's also worth knowing that the NHS patient information for semaglutide describes the medicine as working alongside a reduced-calorie diet and increased activity, not instead of them. At 2.4mg, the combination still matters. Protein intake, staying hydrated, and some strength-based movement all help preserve the muscle mass that supports metabolism during ongoing weight loss. Your prescriber is the right person to talk through specifics.

Some people find progress at the maintenance dose benefits from a brief check-in, our frequently asked questions cover what to expect at different stages of treatment.

The NICE threshold: when 2.4mg is considered not to be working

NICE guidance (TA875) sets a clear benchmark: if you haven't lost at least 5% of your starting body weight after six months on the maintenance dose, continuing treatment should be reviewed. That's an average of roughly one kilogram per month across the period, though in practice the loss tends to be front-loaded. If you started at 100kg, six months on 2.4mg without reaching 95kg is the point at which a prescriber would want to assess next steps.

This threshold exists because semaglutide doesn't produce meaningful weight loss in every person, and continuing indefinitely without response carries cost and side-effect exposure with no benefit. It's a safety check, not a judgement.

For people who do respond, the guidance recognises that treatment may continue for up to two years within a specialist weight management context. Stopping the medicine tends to reverse the weight loss over time, which is why what happens on the maintenance dose long-term is something many people want to understand before they start.

For context on how 2.4mg compares with higher dose formats now available in the UK, including whether the 2.4mg dose actually delivers greater results than lower doses, the full Wegovy dose guide covers the licensed schedule, including the newer 7.2mg option approved by the MHRA in early 2026. And if you're weighing up the cost of staying on treatment privately, the Wegovy price comparison page sets out what private treatment typically involves financially.

Side effects at 2.4mg: what's normal and when to get help

Gastrointestinal side effects (nausea, loose stools, constipation, reflux, burping) are the most commonly reported. They're most likely after a dose step-up, so some people find the move to 2.4mg brings a short recurrence of symptoms they thought had settled. For most, this passes within a fortnight or so, particularly if they're eating smaller meals slowly and avoiding very fatty or rich food. It's a pattern that those who found 0.5mg effective often notice too, as side effects ease and weight loss continues alongside each other.

Fatigue and headache are also reported. These generally ease as the body adjusts.

There are symptoms that need prompt medical attention rather than a waiting approach. Severe stomach pain that radiates through to the back (with or without vomiting) should be assessed urgently, as it can indicate acute pancreatitis. The MHRA flagged this as a known infrequent but serious risk in its January 2026 Drug Safety Update for GLP-1 medicines. Gallbladder symptoms, signs of a serious allergic reaction, and persistent dehydration from vomiting or diarrhoea also warrant contacting a doctor without delay.

You can report any suspected side effects through the MHRA Yellow Card scheme, patients can report directly, not just healthcare professionals. If you have questions about how we monitor patients through treatment, our clinical team page gives a sense of how aftercare works at nume.
