Still Hungry on Wegovy 2.4mg: Why Appetite Suppression Varies

Why does hunger persist at the highest licensed weekly dose?

Semaglutide works by activating GLP-1 receptors that signal fullness to the brain and slow the movement of food through the stomach. At 2.4mg those signals are strong, but they are not a switch. The degree of appetite suppression a person experiences depends partly on how many GLP-1 receptors they express, partly on body composition, and partly on behaviours like meal timing, sleep and stress that regulate hunger hormones independently of the medicine.

There is also a timing effect. In the weeks immediately after a dose increase, many people notice a sharper reduction in appetite that softens once the body acclimates. If you moved from 1.7mg to 2.4mg recently, the more settled level of hunger you feel now may simply be your baseline on this dose rather than a failure. The pattern at 1.7mg is often similar for the same reason.

According to the NHS semaglutide medicines page, nausea and changes in appetite are expected early in treatment. What is less discussed is that the appetite benefit can also arrive more gradually for some people, building across weeks rather than appearing immediately after the injection.

Worth knowing: if hunger was well controlled at 1.7mg and has returned noticeably at 2.4mg, that reversal is unusual and worth a clinical conversation rather than self-management. It can also help to understand how earlier stages of treatment compare, since people who are still hungry on Wegovy 0.25mg often find that the pattern of appetite suppression at the starting dose gives useful clues about how their response develops over time.

Could the timing of your weekly injection be making a difference?

Semaglutide's half-life in the body is around a week, which is why it is injected once weekly. Plasma levels do rise and fall across that window, and some people notice slightly more hunger in the day or two before their next injection is due. This is sometimes called the "pre-dose dip".

If your hunger is worse on a particular day of the week, log it against your injection schedule. Taking your injection on the same day each week keeps levels as steady as possible. The injection site matters less for blood levels than for local tolerability, but rotating between the abdomen, thigh and upper arm (as described in your Patient Information Leaflet) helps prevent the skin changes that can affect absorption over time.

Meal composition also interacts with gastric emptying. Higher-protein, higher-fibre meals tend to extend the fullness signal that Wegovy initiates, whereas fast-digesting, lower-volume meals can leave people feeling hungry again within two hours. This is not unique to semaglutide (it applies to anyone managing their intake) but it is amplified when you are relying on appetite suppression as part of your treatment plan.

If you are unsure whether the dose you are on is right for your situation, that is exactly the kind of thing a prescriber review is designed to address.

Is still feeling hungry a sign that Wegovy 2.4mg is not working for you?

Not necessarily. Hunger and weight loss are related but distinct. You can still be losing weight while feeling hungrier than you did at 1.7mg, and the reverse is also true. The STEP 1 trial, published in the New England Journal of Medicine, found an average 15% body-weight reduction over 68 weeks at 2.4mg, but that average contained a wide spread of individual responses.

The more useful question is whether your weight is still moving in the right direction. If you are still losing weight at 2.4mg and hunger is manageable (even if not fully suppressed), the medicine is doing its job. If weight loss has plateaued and appetite suppression feels absent, that is a different picture, and one that NICE's guidance on semaglutide (TA875) acknowledges: if a patient has not achieved at least 5% weight loss after six months on the maintenance dose, continuing needs clinical review. It is also worth reading about how Wegovy 0.5mg works, since understanding what appetite suppression looks like at that earlier stage can give you a clearer sense of how your overall response to the medicine has changed.

The honest reality is that no medicine eliminates hunger completely for everyone. What Wegovy typically does is lower the set point, you feel less urgently hungry, you feel full sooner, you find it easier to stop. If that effect feels absent to you, tell your prescriber. They can look at whether anything else is affecting your response: medication interactions, hormonal factors, sleep, or simply whether 2.4mg is the right long-term dose for you.

What practical steps can you take while waiting to speak to a clinician?

First, keep a simple log for one or two weeks: record when hunger spikes, what you ate beforehand, how much water you drank, and which day of your injection cycle it falls on. That data is far more useful to a prescriber than a general sense that "the appetite suppression has faded".

Second, review protein intake. People on GLP-1 medicines often eat less overall, which can mean inadvertently eating less protein. Low protein contributes to hunger signals independent of semaglutide's mechanism. Aim for protein at every meal even if portions are small. Your prescriber or a dietitian can give you a specific target.

Third, check you are not confusing thirst with hunger. Gastric slowing can dull thirst cues alongside hunger cues, and mild dehydration drives appetite. Plain water before meals is a simple, low-risk intervention.

If you are thinking about what a review might look like (or whether a different treatment approach could help) speaking to our prescribers is a reasonable next step.
