Calories by Food: Understanding What You Eat on Mounjaro or Wegovy

Different foods carry very different calorie loads for the same volume, which is especially relevant when your appetite is reduced and you are eating less overall. Getting the balance right — enough energy, enough protein, not too much of anything — is something many people on Mounjaro or Wegovy find themselves thinking about more carefully.

Protein-rich foods

Chicken breast, fish, eggs, Greek yoghurt, cottage cheese, and legumes are relatively lower in calories for the amount of protein they deliver. Protein is widely regarded as the most satiating macronutrient, and many people on GLP-1 medicines find prioritising it helps them feel more nourished even when portions are small. Understanding your overall calorie needs alongside protein targets gives a clearer picture of what a good day of eating looks like.

Carbohydrates and starchy foods

Bread, rice, pasta, and potatoes are calorie-dense relative to their protein content but can still form a useful part of a balanced diet. Whole-grain or fibre-rich versions tend to be more filling and gentler on digestion — something many people on GLP-1 medicines appreciate, given that slower stomach emptying is commonly reported.

Fats and calorie-dense foods

Oils, nuts, avocado, cheese, and processed snacks carry a high number of calories per gram. They are not foods to avoid entirely, but their calorie contribution is easy to underestimate — particularly when logging meals informally or eating out.

Vegetables and lower-calorie foods

Non-starchy vegetables — leafy greens, courgette, cucumber, peppers, broccoli — are very low in calories and high in fibre and water content. Building meals around these alongside a protein source is a practical approach many people find works well with a reduced appetite.

If you are thinking about how your overall intake fits together, our guide to understanding a calorie deficit explains the broader picture, and calorie needs for women on GLP-1 medicines covers how requirements can differ.

Knowing roughly what is in your food is one thing — tracking it consistently is another, especially when appetite fluctuates and meals are smaller and less predictable than before. GLP Trackr's AI photo scan is the fastest way to log what you eat: point your camera at a plate and the app estimates calories, protein, and macros instantly, without manual searching.

For packaged foods, the barcode scanner pulls nutritional data in seconds. You can also search manually or save frequently eaten meals so repeat logging takes almost no time at all. Over time, the app builds a picture of your daily intake that you can review alongside your weight and energy trends — useful for spotting patterns and understanding what is and is not working for you.

You can set a daily calorie target and a protein goal inside the app, and your food log feeds directly into those targets so you can see at a glance where you stand. If you want to dig deeper into what calories actually are and why they matter on a GLP-1 journey, that is worth a read too.

GLP Trackr is not a substitute for guidance from your prescriber or doctor — if you have questions about specific nutritional needs or dietary changes alongside your medication, they are the right person to ask. The app helps you observe and record, so those conversations are better informed.
