Understanding Progress on Prescription Weight Loss Drugs
Mounjaro and Wegovy are both prescription-only medicines. Mounjaro's active substance is tirzepatide, a dual GIP and GLP-1 receptor agonist; Wegovy's active substance is semaglutide, a GLP-1 receptor agonist. Both are typically started at a low dose, with any adjustments made by a prescriber over time — the right dose for any individual is always a clinical decision, not a personal one.
Why progress is not just about the scale
Many people focus entirely on weekly weigh-ins, but weight alone can be misleading. Fluid shifts, muscle changes, and natural day-to-day variation all affect the number. Meaningful progress on prescription weight loss drugs tends to show up across a broader set of signals: energy levels, how often you feel hungry, sleep quality, mood, and body measurements alongside weight. Tracking all of these together makes it much easier to spot genuine trends rather than reacting to normal fluctuation.
Plateaus are common and worth understanding
A period where weight stops moving — often called a plateau — is a commonly reported experience on GLP-1 medicines. It does not necessarily mean the medicine has stopped working. Factors such as calorie intake, protein, activity, sleep, and where someone is in their titration schedule can all play a role. Keeping a consistent log during a plateau gives you concrete data to discuss with your prescriber rather than relying on memory.
Side effects can affect how you track progress
Commonly reported side effects of prescription weight loss drugs include nausea, fatigue, digestive changes, and reduced appetite. These can influence food intake, energy, and how you feel day to day — all of which are relevant to understanding your results. You can read more about the broader weight loss journey and explore information on prescription weight loss drug access or how these medicines are prescribed.
If side effects feel severe, persistent, or worrying at any point, contact your healthcare professional promptly — do not wait for a scheduled appointment.

Tracking Your Weight Loss Drug Journey with GLP Trackr
GLP Trackr is built specifically for people already on Mounjaro or Wegovy, and the most useful place to start is the weight and progress tracking tools. Log your weight daily or weekly and the app builds a chart that smooths out day-to-day noise, showing the actual trend over time — including a plateau forecast that flags when your weight has stalled so you can bring it to your next appointment rather than being caught off guard.
Beyond the scale, the daily check-in lets you record mood, energy, food noise, sleep, and water in around 30 seconds. Over weeks, patterns emerge: the weeks where sleep dropped, or protein intake fell, often correlate with slower progress. The app's correlation explorer surfaces these links from your own data, giving you something specific and personal to discuss with your prescriber.
The community feature means you are not navigating this alone — connecting with others on the same medicines, at similar stages, can make a real difference to staying consistent through the harder stretches.
GLP Trackr helps you record what is happening so you can have better, more informed conversations with your prescriber — it is not a substitute for their guidance, and any decisions about your dose or treatment remain theirs to make.

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.
Mounjaro (tirzepatide) and Wegovy (semaglutide) are prescription-only, once-weekly injectable medicines that act on appetite-regulating pathways. They are prescribed by a doctor or clinician and are not available without a prescription. Suitability and dosing are always decided by a prescriber.
Results vary considerably between individuals and depend on many factors including diet, activity, adherence, and how the body responds. No specific amount can be guaranteed. Your prescriber is best placed to give you realistic expectations based on your personal health history.
A plateau — where weight stops moving for a period — is commonly reported on GLP-1 medicines and does not necessarily mean the medicine has stopped working. Factors like calorie intake, protein, sleep, and titration stage can all play a role. Tracking consistently and discussing the data with your prescriber is the most useful next step.
Commonly reported side effects include nausea, digestive changes, fatigue, and reduced appetite. These are often most noticeable after a dose adjustment and may ease over time. If side effects are severe, persistent, or concern you, contact your healthcare professional promptly rather than managing them alone.
GLP Trackr is a companion app for people already prescribed Mounjaro or Wegovy. It logs weight, mood, energy, food, doses, and side effects, and surfaces trends and patterns over time — helping you track your journey and prepare for conversations with your prescriber. It is not a medical service.
