What to Count — and Why — When Appetite Changes on GLP-1
Reduced appetite is one of the most commonly reported effects of GLP-1 receptor agonists like semaglutide (Wegovy) and tirzepatide (Mounjaro). For many people, this means eating significantly smaller portions — which is helpful for weight management, but can also make it easy to under-eat protein or key nutrients without realising it.
Calories: a floor as much as a ceiling
Most calorie-counter guidance focuses on staying under a target. On a GLP-1 medicine, the more common concern is eating enough. Many people find they need a conscious effort to reach a reasonable daily intake — general educational guidance typically points to ranges above 1,200 kcal for women and 1,500 kcal for men as a rough floor, though your ideal number depends on your individual circumstances. Always discuss specific targets with your prescriber or doctor rather than setting them based on general figures alone.
Protein: the priority macro
Protein supports muscle maintenance during weight loss and tends to promote satiety — both useful on a GLP-1 journey. General nutrition guidance commonly suggests aiming for around 1.2–1.6 g of protein per kg of body weight during active weight loss, though this varies by individual. Tracking it daily is the only reliable way to know whether you are hitting a useful range.
What a diet app calorie counter actually needs to do
A good calorie counter for this context needs to be fast (because appetite windows can be short), accurate (because portions are smaller and every gram matters more), and protein-aware. If you are exploring your options, you can compare approaches in our calorie counter guide or look specifically at app-based calorie counters built for this journey. For the broader picture of eating in a calorie deficit, the calorie deficit hub covers how that works alongside GLP-1 medicines.

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.

How GLP Trackr Works as Your Diet App Calorie Counter
GLP Trackr's food logging is built specifically for people on Mounjaro and Wegovy — not a generic fitness tracker bolted on as an afterthought. The standout feature is the AI photo scan: point your camera at a meal and get an instant breakdown of calories, protein, and macros, with no manual entry required. On days when appetite is low and eating feels like a task, removing the friction of logging matters.
For packaged foods, a barcode scanner pulls in nutrition data instantly. And for anything else — home-cooked meals, coffee shop orders, snacks — there is a searchable food database to log manually in seconds.
Beyond individual meals, GLP Trackr lets you set daily targets for calories, protein, water, and fibre, and tracks your progress against them in real time. Over time, the insights feature can help you spot patterns — for example, whether days with higher protein intake correlate with better energy or fewer cravings — giving you something concrete to discuss at your next prescriber appointment.
If you want a structured starting point, the diet app overview explains how GLP Trackr brings food, dose, and progress tracking together in one place.
GLP Trackr is a tracking tool, not a clinical service — it helps you record and understand your own data. For personalised guidance on calorie targets or nutrition goals, your prescriber or doctor is the right person to ask.

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.
