How These Medicines Support Weight Loss
Tirzepatide and semaglutide belong to a class of injectable medicines that act on GLP-1 receptors, which are involved in regulating appetite and blood sugar. Tirzepatide also acts on GIP receptors, making it a dual-action medicine. Both are started at a low dose and adjusted over time by a prescriber — the pace and final dose are individual decisions made in partnership with your healthcare team, not something to self-manage.
What these medicines commonly do
Many people prescribed these medicines report a noticeable reduction in appetite and a quietening of "food noise" — the persistent thoughts about food that can make sticking to a healthier eating pattern difficult. Slower gastric emptying is also commonly reported, which can contribute to a greater sense of fullness after smaller meals. These effects vary from person to person, and results are never guaranteed.
Progress is rarely a straight line
Weight loss on GLP-1 and dual GIP/GLP-1 medicines tends to be gradual and non-linear. Plateaus are common and do not necessarily mean the medicine has stopped working — factors like sleep, protein intake, activity, hydration, and stress all interact with progress. Tracking the full picture, not just the number on the scale, gives a far more accurate view of how your journey is going.
If you are exploring this topic as part of a broader look at your options, our guide to weight loss on GLP-1 medicines covers the wider journey in more detail. You may also find it useful to read about tirzepatide (sometimes spelled Monjaro) for weight loss and how people are using it in practice.
It is worth noting that some people research adjacent approaches alongside medical treatment — for example, hypnotherapy for weight loss is one area some people explore in parallel, though any combination of approaches should always be discussed with your prescriber.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.

Tracking Your Weight-Loss Progress with GLP Trackr
One of the most practical ways to stay motivated and informed on this journey is to track more than your weight. GLP Trackr's weight and body tracking feature lets you log your weight, body measurements, and weekly transformation so you can see change over time — even when the scale feels stuck.
Beyond the scale, the app's insights and analytics tools surface patterns you might otherwise miss: how your sleep or protein intake on a given week relates to your results, and whether a plateau is likely to be temporary. The daily morning check-in — which takes around 30 seconds to complete — captures mood, energy, food noise, sleep, and water alongside your weight, building a richer dataset than a single number ever could.
If you are curious about how other medicines are sometimes compared in this space, our page on statins and weight loss explores a different class of medication entirely, which may be relevant if you are managing multiple conditions.
All data you log belongs to your journey and can be compiled into a clear summary to bring to your prescriber appointments — useful for discussing how things are going and whether any adjustments are needed.
A note on medical decisions: any questions about whether these medicines are suitable for you, what dose you should be on, or whether to continue treatment should always be directed to your prescriber or doctor. GLP Trackr helps you record and understand your own data — it is not a substitute for clinical advice, and nothing here should be read as a recommendation to start, stop, or change any medication.

GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.

Frequently asked questions.
Tirzepatide (Mounjaro) and semaglutide (Wegovy) are injectable, prescription-only medicines prescribed for weight management. Both act on GLP-1 receptors; tirzepatide also acts on GIP receptors. Suitability and prescribing decisions are always made by a qualified healthcare professional.
Results vary considerably between individuals and depend on dose, lifestyle factors, and how long the medicine is taken. No specific outcome can be guaranteed. Your prescriber is the best person to give you a realistic picture based on your own health history.
Plateaus are common and can reflect changes in metabolism, calorie intake, activity, sleep, or hydration — not necessarily that the medicine has stopped working. Tracking the full picture over time, rather than focusing solely on the scale, can help identify patterns worth discussing with your prescriber.
Both tirzepatide and semaglutide were originally developed for type 2 diabetes management and have more recently been approved in many countries for chronic weight management. They are prescription-only medicines; eligibility and access are determined by a prescriber.
GLP Trackr lets you log weight, measurements, mood, energy, food noise, sleep, and hydration alongside your doses. Its insights tools surface patterns in your data over time, and a doctor report summary can be shared with your prescriber at appointments.
