Building a Diet Plan That Works Alongside GLP-1 Medicines
GLP-1 and dual GIP/GLP-1 medicines like Wegovy (semaglutide) and Mounjaro (tirzepatide) act on appetite-regulating pathways and are commonly associated with reduced food noise and a greater sense of fullness. Eating less is common — but eating well is what helps protect energy levels, hair health, and muscle mass over time.
Prioritise protein at every meal
Many people on GLP-1 medicines experience some degree of weight loss and fatigue or tiredness, particularly in the earlier stages. Adequate protein — commonly suggested in the range of 1.2–1.6 g per kilogram of body weight for active adults, though your own needs vary — helps preserve lean muscle as weight changes. Good sources include eggs, Greek yoghurt, legumes, fish, chicken, and tofu. Explore a structured meal plan designed around GLP-1 eating for practical ideas.
Eat for nutrient density, not just calories
Smaller portion sizes mean less room for low-quality foods. Weight loss and anaemia, weight loss and hair fall, and weight loss and tiredness are all concerns that can arise when nutrient intake drops too low alongside calorie restriction. Prioritising iron-rich foods (lentils, dark leafy greens, lean red meat), zinc, and B vitamins helps address these risks. If you notice significant fatigue, hair changes, or other persistent symptoms, discuss them with your prescriber or doctor — they can check whether nutritional deficiencies are a factor.
Manage side effects through food choices
Nausea, reflux, and digestive discomfort are commonly reported, especially after dose changes. Smaller, more frequent meals, gentle foods (plain crackers, rice, cooked vegetables), and limiting high-fat or heavily spiced dishes often help. Staying well hydrated matters too, particularly if loose stools are an issue. A calorie deficit guide for GLP-1 users can help you understand how to balance reduced intake without going too low.
A note on weight loss and pancreatitis
If you experience persistent, severe abdominal pain during your treatment, do not manage it through diet changes alone — contact your healthcare professional promptly. For background on this topic, read about Mounjaro and pancreatitis. Diet adjustments are not a substitute for medical assessment of serious symptoms.
Other changes you may notice
Weight loss and loose skin, changes to your menstrual cycle (weight loss and period irregularities), itching skin, and shifts in energy are all topics worth tracking over time. Night sweats can also occur — see weight loss and night sweating for more context. Keeping a record helps you spot patterns and have informed conversations with your prescriber.

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 Helps You Track Food and Nutrition on Your Journey
Logging food when appetite is low and portion sizes are unpredictable can feel tedious — GLP Trackr's AI photo scan makes it simple. Point your camera at a meal and get an instant breakdown of calories, protein, and macros without manually entering anything. For packaged foods, the barcode scanner works just as quickly.
Beyond individual meals, the app lets you set protein and calorie targets suited to your journey, browse a library of GLP-1-friendly recipes, and access meal plans built around gentle-on-the-stomach, protein-first options. Over time, the insights feature surfaces patterns — for example, how your food choices on a given day relate to your energy or weight trend the next — giving you something concrete to discuss at your next prescriber appointment.
If you want to bring a clear picture of your nutrition and progress to that appointment, the doctor report feature pulls your logged data into a summary your healthcare team can actually use.
Always follow the guidance of your prescriber or doctor on diet and nutrition — they know your full health history. GLP Trackr helps you record what's happening so those conversations are more informed, not replace the conversations themselves.

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.
Many people on GLP-1 medicines find that protein-rich, nutrient-dense meals work best — eggs, legumes, fish, lean meat, and cooked vegetables are commonly well-tolerated. Smaller, frequent meals often suit reduced appetite better than large ones. Your prescriber or doctor can give personalised guidance.
Weight loss and hair fall or tiredness can occur when calorie and nutrient intake drops significantly. Ensuring adequate protein, iron, zinc, and B vitamins through diet may help. If these symptoms are persistent or severe, discuss them with your healthcare professional to rule out nutritional deficiencies.
General guidance for adults during weight loss often suggests around 1.2–1.6 g of protein per kilogram of body weight, though individual needs vary. Your prescriber or a registered dietitian can advise on what is appropriate for you specifically.
GLP Trackr lets you log meals by scanning a photo or a barcode, or by searching manually. The app tracks calories, protein, and macros automatically, so you can see whether your intake aligns with your goals without manual calculations.
Diet plays an important role alongside medication for people managing blood sugar. The right balance of carbohydrates, protein, and fibre is best discussed with your prescriber or doctor, who can tailor advice to your specific health conditions and treatment plan.
