Understanding GLP-1 Medicines and Weight Management
GLP-1 receptor agonists work by acting on appetite-regulating pathways in the body. Wegovy contains semaglutide, a GLP-1 receptor agonist; Mounjaro contains tirzepatide, which acts on both GLP-1 and GIP receptors. Both are once-weekly injectable medicines, typically started at a low dose and adjusted over time under prescriber supervision. Neither is suitable for everyone, and suitability is always determined by a qualified healthcare professional.
Why there is no single "best" option
Clinical studies report different outcomes across different populations, and individual responses to these medicines vary considerably. Factors such as other health conditions, existing medications, and personal tolerance all influence how well a particular medicine works for any one person. Comparing the two to persuade yourself toward one is less useful than having an open conversation with your prescriber about what is right for your situation.
If you are already prescribed one of these medicines and want to understand the broader landscape of how GLP-1 medicines support weight loss, that context can help you engage more meaningfully with your healthcare team. For a wider look at approaches to weight management, the weight loss tracking guide covers how to measure and understand your journey over time.
What actually shapes your results
Progress on a GLP-1 medicine is influenced by many things beyond which medicine you take: how consistently you take it, the lifestyle changes you make alongside it, your sleep, stress levels, protein intake, and how your body responds over time. Focusing on what you can observe and track — rather than searching for a "better" medicine — tends to be more productive once you are already prescribed and underway.

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 GLP-1 Progress With GLP Trackr
Once you are on a GLP-1 medicine, the most valuable thing you can do is build a clear, consistent picture of how your body is responding — and that is exactly what GLP Trackr is built for.
The app's weight and body tracking features let you log your weight, body measurements, and weekly changes, then visualise your transformation over time through charts and trends. Because progress on GLP-1 medicines is rarely a straight line, seeing the broader pattern — rather than reacting to day-to-day fluctuations — helps you stay motivated and grounded.
Beyond the scale, GLP Trackr's insights and analytics surface correlations in your own data: how your sleep, food intake, or activity levels relate to your results. The plateau forecast and weight intelligence features help you understand stalls before they become discouraging, so you can bring informed questions to your next prescriber appointment rather than wondering what is happening.
It is worth noting that progress looks different for everyone, and GLP Trackr does not predict or guarantee outcomes — it helps you understand your journey as it unfolds. Any concerns about how your medicine is working, or whether your current prescription is right for you, should always be discussed with your prescriber or doctor. They know your full history and are the right person to make those calls.
You might also find it useful to explore complementary approaches to weight management that some people use alongside their prescribed treatment, or to read about other medicines sometimes discussed in the context of weight — bearing in mind that any changes to your treatment are always a matter for your healthcare professional.

The Most Advanced GLP-1 Brain Ever Built.
The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.
Knows Your Cycle
GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
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.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

Frequently asked questions.
There is no universally best GLP-1 medicine for weight loss. Both Mounjaro (tirzepatide) and Wegovy (semaglutide) are used for weight management, but which is appropriate for any individual depends on their health history and clinical assessment. Your prescriber or doctor is the right person to make that decision.
Mounjaro contains tirzepatide, which acts on both GLP-1 and GIP receptors. Wegovy contains semaglutide, a GLP-1 receptor agonist. Both are once-weekly injectables used for weight management under prescriber supervision. Individual responses vary, and a healthcare professional determines which is suitable for each person.
Tracking weight, measurements, food intake, energy, and mood over time gives a fuller picture than the scale alone. Apps like GLP Trackr let you log these data points, visualise trends, and spot patterns — helping you have more informed conversations with your prescriber about how your treatment is going.
Weight loss on GLP-1 medicines is rarely a straight line. Plateaus and fluctuations are commonly reported and can be influenced by factors like sleep, stress, food choices, and how the body adapts over time. Tracking the broader trend — rather than day-to-day changes — helps put progress in perspective.
Any decision to switch, stop, or change your prescribed medicine must be made with your prescriber or doctor — never independently. If you feel your current treatment is not working as expected, log your concerns and progress data and bring them to your next appointment for a proper clinical review.
