What GLP-1 Medication Is and How It Works
GLP-1 stands for glucagon-like peptide-1, a naturally occurring hormone involved in regulating appetite and blood sugar. GLP-1 receptor agonists mimic this hormone, signalling to the brain that you are full and slowing the rate at which the stomach empties. The result, for many people, is a noticeable reduction in appetite and what is often described as reduced "food noise" — the persistent background pull toward eating.
The two most widely prescribed GLP-1 medicines for weight management are:
- Wegovy (semaglutide) — a GLP-1 receptor agonist, given as a once-weekly injection
- Mounjaro (tirzepatide) — a dual GIP and GLP-1 receptor agonist, also given once weekly; you can read more on the Mounjaro overview page
Both are prescription-only medicines. Suitability, dose, and any adjustments are decisions made by your prescriber or doctor — not something to navigate alone. For a broader introduction to how these medicines are classified and used, the guide to what GLP-1 medication is covers the background in more detail.
It is also worth knowing that these medicines are subject to additional monitoring in many countries. Any side effects you experience should be reported to your healthcare professional and, where applicable, to your national reporting scheme (such as the UK's Yellow Card scheme). The GLP-1 information hub has further reading on the class as a whole.
Because both medicines work similarly but have distinct active substances and dose structures, people sometimes wonder how they compare. That question — and why the answer ultimately rests with your prescriber — is explored on the Mounjaro medication detail page.

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.

Staying Consistent with Your GLP-1 Medication Using GLP Trackr
One of the most practical challenges of a weekly injectable medicine is simply keeping track — which dose you are on, when your last injection was, and where you injected it. GLP Trackr's dose and injection-site logging makes this straightforward: every shot is recorded with its date, dose strength, and site (abdomen, thigh, or upper arm), and the app tracks your rotation history so it can suggest your next site automatically.
Beyond the injection itself, GLP-1 life involves a lot of moving parts — appetite changes, side effects, weight shifts, and energy fluctuations. GLP Trackr's daily check-in lets you log mood, energy, food noise, and sleep in around 30 seconds each morning, building a picture of your journey over time. The insights feature then surfaces patterns in your own data — useful context to bring to your next prescriber appointment.
GLP Trackr is a tracking and journaling companion; it does not replace the guidance of your prescriber or doctor. If you have questions about your dose, your side effects, or whether this medication is right for you, your healthcare professional is the right person to ask.
Ready to bring some structure to your weekly routine? GLP Trackr is free to try for 7 days — available on the App Store and Google Play. Log your first dose, set a weekly reminder, and start seeing your journey take shape.

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.
GLP-1 medications are prescription-only medicines that mimic the glucagon-like peptide-1 hormone to help regulate appetite and support weight management. Examples include semaglutide (Wegovy) and tirzepatide (Mounjaro). They are taken as once-weekly injections and must be prescribed by a doctor or healthcare professional.
GLP-1 medicines act on appetite-regulating pathways in the brain, increasing feelings of fullness and reducing appetite — often described as lowering 'food noise'. They also slow stomach emptying. Individual results vary, and the medicine works alongside diet and lifestyle changes under clinical supervision.
No. Suitability is assessed by a prescriber based on your individual health history, other medicines you take, and clinical criteria. These are prescription-only medicines for a reason — always follow the guidance of your prescriber or doctor about whether they are appropriate for you.
Commonly reported side effects include nausea, vomiting, diarrhoea, constipation, and fatigue, particularly early in treatment or after a dose change. These often ease over time for many people. If side effects are severe, persistent, or worrying, contact your healthcare professional promptly.
GLP Trackr lets you log each injection (dose, date, site), track side effects over time, monitor weight and wellbeing, and set weekly dose reminders. It is a tracking companion — not medical advice — designed to help you stay consistent and bring useful data to conversations with your prescriber.
