How Weight Loss on Semaglutide Generally Works
Semaglutide (the active substance in Wegovy) is a GLP-1 receptor agonist. It acts on appetite-regulating pathways in the brain and slows the rate at which the stomach empties, which many people experience as reduced hunger and less preoccupation with food — sometimes described as a quietening of "food noise." These effects can make it easier to eat less without the constant effort that unaided calorie restriction often demands.
Progress is rarely linear
Many people see more noticeable changes in the earlier months of treatment, with progress sometimes slowing or plateauing as the body adapts. This is common and does not necessarily mean the medicine has stopped working. Factors like sleep quality, protein intake, activity levels, and how consistently doses are taken all appear to influence results alongside the medicine itself.
The dose and its role
Wegovy is typically started at a low dose and increased gradually over time, with the maximum dose of semaglutide for weight loss reached only after a stepped titration period — a process that your prescriber manages based on your individual response and tolerability. Decisions about dose belong entirely with your prescriber; this page is here to help you understand and track your journey, not to advise on dose changes.
Semaglutide versus tirzepatide for weight loss
Some people researching their options come across comparisons between tirzepatide (the active substance in Mounjaro) and semaglutide. Both are prescription-only medicines that work on GLP-1 pathways; tirzepatide also acts on GIP receptors. Any decision about which medicine is right for you is one for your prescriber — it depends on your health history, how your body responds, and other factors only a clinician can assess. You can read more about Mounjaro for weight loss if that comparison is relevant to your situation.
It is also worth knowing that medication alone is one part of the picture. Many people find that behavioural approaches such as hypnotherapy are explored alongside medical treatment, and questions about how long to stay on semaglutide are very common as the journey continues. For a broader look at managing your weight on a GLP-1 medicine, the weight loss hub covers the full picture.

Tracking Your Semaglutide Journey with GLP Trackr
One of the most useful things you can do on a semaglutide journey is capture the full picture — not just your weight, but your energy, mood, sleep, and how your body is changing in ways a single number cannot show. That is where GLP Trackr comes in.
Progress tracking that goes beyond the scale
GLP Trackr's weight and body tracking feature lets you log your weight, measurements, and weekly changes in one place, with charts that reveal trends over time rather than the noise of day-to-day fluctuations. When progress feels slow, seeing a clear trend line over several weeks is often genuinely reassuring — and it is the kind of context that is easy to lose without a consistent log.
Insights to understand what is driving your results
The app's insights and analytics tools go a step further: the correlation explorer and plateau forecast help you see how variables like sleep, protein intake, or activity levels relate to your weight trend. This turns scattered daily data into something you can actually learn from — and bring to your prescriber appointments as a clear, organised summary.
Logging food effortlessly on reduced appetite
Many people on semaglutide find their appetite drops significantly, which makes hitting protein targets a real challenge. GLP Trackr's AI photo scan lets you point your camera at a meal and get an instant calorie and protein breakdown — useful when you are eating less but want to make sure what you do eat is working hard for you.
Always follow the guidance of your prescriber or doctor — they know your full medical history and are best placed to interpret your progress and advise on your treatment. GLP Trackr helps you record your journey so those conversations are better informed; it is not a substitute for clinical advice.
Start capturing your full semaglutide journey — weight trends, body changes, food, and daily wellbeing — all in one place. GLP Trackr is available free on the App Store and Google Play, with a 7-day trial so you can see what consistent tracking feels like before you commit.

Frequently asked questions.
Weight loss on semaglutide varies considerably between individuals and depends on factors including dose, diet, activity, and how long treatment continues. No specific amount can be guaranteed. Your prescriber is best placed to set realistic expectations based on your personal health profile.
Wegovy's highest dose strength is 2.4 mg, reached after a gradual titration schedule that typically takes several months. Your prescriber manages this process based on your response and tolerability — dose decisions should never be made independently.
Plateaus are common on semaglutide and do not necessarily mean the medicine has stopped working. Sleep, protein intake, activity, and consistency all influence results alongside the medication. Tracking these variables over time can help you and your prescriber identify patterns worth addressing.
Semaglutide acts on GLP-1 receptors; tirzepatide acts on both GLP-1 and GIP receptors. Both are prescription-only injectable medicines. Which is more appropriate for any individual is a decision for their prescriber, based on health history and clinical factors.
GLP Trackr lets you log weight, measurements, food, mood, sleep, and energy in one place, with charts and insights that reveal trends over time. It also generates a summary you can share with your prescriber — it supports your journey but is not a medical tool.
