The GLP-1 Diet: What to Eat When You're on Mounjaro or Wegovy

There is no single official "GLP-1 diet," but the phrase reflects a practical eating approach that works with the way these medicines affect appetite and digestion. Because GLP-1 receptor agonists slow gastric emptying and reduce hunger signals, many people naturally eat less — the challenge shifts from willpower to making nutritious choices within a smaller appetite window.

Protein first

Protein is the cornerstone of eating well on a GLP-1 journey. When overall food intake drops, getting enough protein helps preserve lean muscle mass. Many people aim to include a good protein source — eggs, fish, chicken, legumes, Greek yoghurt, cottage cheese — at every meal. General guidance from nutrition researchers commonly suggests somewhere in the range of 1.2–1.6 g of protein per kilogram of body weight for people managing their weight, though your own targets are best agreed with your prescriber or a registered dietitian.

Easy-to-digest, nutrient-dense foods

Rich, fatty, or heavily spiced meals can worsen nausea and reflux that some people experience, particularly after a dose increase. Foods that tend to sit more comfortably include:

• Lean proteins: poultry, white fish, eggs, tofu
• Cooked or soft vegetables rather than large raw portions
• Low-fat dairy or dairy alternatives
• Oats, rice, and other easily digestible wholegrains
• Soups and broths when appetite is very low

Staying hydrated

Drinking enough water matters on any weight-management journey, but it becomes especially important when nausea or reduced appetite may discourage eating and drinking. Sipping water steadily through the day, rather than large amounts at once, tends to be more comfortable alongside slower gastric emptying.

Foods many people choose to limit

Ultra-processed snacks, sugary drinks, alcohol, and very high-fat foods are commonly reported to amplify GI side effects and offer little nutritional return for the calorie spend. This is not a strict exclusion list — it is general guidance based on what many people find works better.

For structured meal ideas, take a look at our GLP-1 diet plan guide, or browse sample diet menus for weight loss built around these principles. If you want to understand the broader concept in more depth, our page on what the GLP diet means covers it in detail. All of this sits within the wider context of a calorie deficit and how it works — useful background reading for your journey.

When appetite is unpredictable and meals are smaller, keeping track of what you're actually eating becomes both more important and more effort — which is exactly why GLP Trackr includes an AI-powered food photo scanner. Point your camera at a meal and the app estimates calories, protein, and macros instantly, no manual entry required. It is one of the quickest ways to stay aware of your protein intake on days when appetite is low and cooking feels like too much.

Beyond logging individual meals, GLP Trackr offers a library of GLP-1-friendly recipes and meal plans built around the protein-first, gentle-on-the-stomach approach described above — with easy swaps and shopping-list support. You can also set a daily protein target and track progress toward it alongside your calorie and water goals, so the numbers work together rather than feeling like separate tasks.

If you want to explore a dedicated GLP-1 diet app designed around how these medicines change your relationship with food, GLP Trackr is built precisely for that.

Food choices are one part of a bigger picture — the app brings dose logs, weight trends, and how you feel day-to-day together in one place, so you can see how your eating patterns connect to your progress over time.

A note on personalised targets: the calorie and protein figures in the app are tools to help you track, not medical prescriptions. Always follow the nutritional guidance your prescriber, doctor, or a registered dietitian has given you — they know your full health history and can advise on what is right for you specifically.

Ready to take the guesswork out of eating on your GLP-1 journey? GLP Trackr is available free on the App Store and Google Play, with a 7-day trial so you can explore every feature — snap a meal, set your protein goal, and see how it feels.
