Why Calorie Counting Matters Differently on a GLP-1 Medicine
Many people on Mounjaro (tirzepatide) or Wegovy (semaglutide) notice a significant drop in appetite — often described as reduced "food noise". That can make eating less feel easy, but it also raises a common challenge: getting enough protein and essential nutrients when overall food intake falls. Tracking calories and macros helps you spot whether you are eating too little as well as too much.
What to focus on when logging food
- Protein first: Protein supports muscle preservation during weight loss. Many people on GLP-1 medicines aim for a higher protein proportion of their diet — general guidance often points toward 1.2–1.6 g per kg of body weight, though your own targets should be discussed with your prescriber or a registered dietitian.
- Calorie floor, not just ceiling: Eating far too few calories over time can lead to fatigue and nutrient gaps. Logging helps you see if you are consistently under-eating.
- Meal timing and tolerance: Slower gastric emptying is commonly reported on these medicines. Smaller, more frequent meals often sit more comfortably — logging helps you identify which meals and timings work best for your body.

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.
AI Meal Tracking. Built for GLP 1 Appetites.
Point your camera at any meal and let our AI do the rest. Breakfast, doses, weight, mood all tracked in seconds.
How GLP Trackr Works as a Free iPhone Calorie Counter
The fastest way to log a meal is to point your camera at it. GLP Trackr's AI photo scan recognises what is on your plate and returns an instant calorie, protein, and macro breakdown — no typing, no searching. On low-appetite days when cooking is minimal, the barcode scanner handles packaged foods just as quickly, and a manual search covers everything else.
Built around GLP-1 eating patterns
Beyond simple logging, GLP Trackr lets you set daily targets for calories, protein, water, and fibre — so you can see at a glance whether you are hitting the numbers that matter for your journey. The app also includes a library of GLP-1-friendly meal plans and recipes built around protein-rich, gentle-on-the-stomach options, which takes the thinking out of meal planning when appetite is low.
All your food data feeds into the app's insights — helping you see patterns like how protein intake on a given day relates to energy or progress over time. You can review a broader calorie counter app guide or look at the free calorie counter options to compare what different tools offer.
GLP Trackr is available free on the App Store for iPhone, with a 7-day free trial so you can explore every feature before committing. Download it on the App Store or Google Play and see how effortless food logging can be when it is built specifically for GLP-1 life.
GLP Trackr is an informational tracking tool, not a substitute for dietary advice from your prescriber or a qualified nutrition professional. If you have questions about calorie or protein targets specific to your health situation, your healthcare team is the right place to start.

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 Trackr is a free iPhone app designed specifically for people on GLP-1 medicines like Mounjaro and Wegovy. It includes AI photo scanning, barcode logging, and protein and calorie targets, with a 7-day free trial available on the App Store.
General guidance often suggests around 1.2–1.6 g of protein per kg of body weight during weight loss, but your individual target should be confirmed with your prescriber or a registered dietitian. A calorie counter app helps you see whether you are hitting that range each day.
Yes — in fact, tracking is especially useful when appetite is suppressed, as it helps you check you are eating enough protein and calories. Quick-logging tools like AI photo scanning and barcode scanners make it practical even on days when eating feels like a low priority.
The quickest method is an AI photo scan — take a picture of your meal and the app returns a nutrition breakdown instantly. Barcode scanning works well for packaged foods, and a manual search covers everything else. GLP Trackr offers all three options.
Many people find their appetite and portion sizes change significantly on Mounjaro or Wegovy. Tracking helps ensure protein intake stays adequate and that overall calories do not drop too low. Focus tends to shift from a ceiling to also maintaining a sensible floor.
