The Best Diet Regimen for Weight Loss on Mounjaro or Wegovy

There is no single eating plan that suits everyone on Mounjaro or Wegovy, but some patterns consistently work well alongside the appetite changes these medicines bring.

Prioritise protein at every meal

Protein helps preserve muscle mass during weight loss and promotes a sense of fullness — something that matters even more when total food intake drops. Many people find aiming for roughly 1.2–1.6 g of protein per kg of body weight each day a useful general target, though the right amount for you is worth discussing with your prescriber or a registered dietitian. Practical high-protein choices include eggs, Greek yoghurt, cottage cheese, lean poultry, fish, legumes, and tofu.

Build meals around volume and fibre

Non-starchy vegetables, wholegrains, and legumes add bulk and fibre without a large calorie load. Fibre also slows digestion and supports gut health, which can be helpful given the gastrointestinal side effects some people experience. A protein-led breakfast sets a strong foundation for the day.

Keep meals smaller and gentler

Slower gastric emptying means large meals can feel uncomfortable. Smaller portions eaten more frequently — and chewing thoroughly — often sit far better. Foods that are heavily fried, very rich, or high in simple sugars can intensify nausea for some people, so many find it worth reducing these during dose-adjustment periods.

Pair nutrition with movement

An exercise regimen for weight loss complements rather than replaces dietary changes. Walking — including treadmill workouts — is accessible and low-impact; a running regimen or gym workout regimen adds cardiovascular and resistance benefits. Resistance training in particular helps protect muscle during a calorie deficit. Even a modest increase in daily steps supports overall progress. Understanding your calorie picture matters too — see our guide to eating in a calorie deficit for the context behind the numbers.

Consider meal replacements thoughtfully

Some people use meal substitutes for weight loss to simplify protein tracking on days when appetite is very low. If you consider this route, choose options that are high in protein and fortified with key micronutrients, and discuss suitability with your prescriber or doctor.

Knowing what to eat is one thing; logging it consistently — especially when appetite is unpredictable — is another. GLP Trackr's AI food photo scan makes this effortless: point your camera at a meal and get an instant breakdown of calories, protein, and macros without manually searching for every ingredient. On days when appetite is very low and meals are small, this removes the friction that often causes people to stop tracking altogether.

Alongside food logging, you can set a daily protein target so you can see at a glance whether you are hitting the intake that supports muscle preservation. The app's meal plans and recipe library are built around GLP-1-friendly eating — higher protein, gentler on the stomach, and practical for smaller appetites.

The daily check-in also lets you log energy levels and how much "food noise" you are experiencing, so you can start to see how your diet regimen, movement, and weekly dose cycle relate to one another over time. That kind of joined-up picture is genuinely useful to bring to appointments with your prescriber or doctor.
