NHS Diet Plan for Weight Loss: Practical Eating Guidance for Your GLP-1 Journey

NHS dietary guidance for weight loss generally emphasises reducing overall calorie intake, eating plenty of vegetables and fruit, choosing wholegrain carbohydrates, and including lean protein at every meal. These principles translate well to life on Mounjaro or Wegovy, where appetite is often lower and portion sizes naturally shrink.

Protein first

With a reduced appetite, it is easy to eat less overall — but if the protein is missing, the body can lose muscle alongside fat. Many people find it helpful to build each meal around a protein source first: eggs, fish, chicken, legumes, low-fat dairy, or tofu. Aiming for a meaningful amount of protein at each meal (rather than saving it all for one sitting) tends to work well with the slower gastric emptying that is commonly reported on GLP-1 medicines.

Vegetables and fibre

Non-starchy vegetables — leafy greens, courgette, broccoli, cucumber, peppers — are low in calories and high in fibre, supporting digestion and helping you feel comfortable after smaller portions. Wholegrain options (oats, brown rice, wholemeal bread) offer longer-lasting energy without large blood-sugar spikes.

What to limit

Highly processed foods, sugary drinks, and high-fat fast food tend to be less well tolerated by many people on GLP-1 medicines — nausea and discomfort are commonly reported after rich or greasy meals. Keeping alcohol moderate is also worth considering, as it adds calories with little nutritional value and can affect how you feel on treatment.

For a fuller practical framework, the diet plan for weight loss on GLP-1 guide covers meal-by-meal approaches in more detail. If you are curious about what a balanced eating plan looks like day to day, the principles of a good diet plan for weight loss page is a useful companion. And if you are thinking about lower-carbohydrate approaches, the keto diet plan for weight loss page explores how that fits with GLP-1 treatment. Understanding your calorie deficit is a helpful backdrop to all of this — it explains why the energy balance matters and how to think about it sustainably.

Knowing what to eat is one thing; keeping track of it when appetite is low and portions are small is another. The GLP Trackr food-logging feature is built around making that as effortless as possible — point your phone camera at a meal and the AI photo scan estimates the calories, protein, and macros instantly. No manual searching, no guesswork, no faff when you only have the appetite for a few bites.

You can also set a daily protein target so you can see at a glance whether you are hitting it — useful when reduced hunger makes it easy to under-eat on protein without realising. The meal plan and recipe library includes GLP-1-friendly ideas built around protein and gentle-on-the-stomach ingredients, so you are never staring at an empty plate wondering what will actually sit well.

Everything you log feeds into your weekly insights, so you can start to see patterns: do higher-protein days correlate with better energy or steadier weight? That kind of personal data is far more useful than a generic plan, and it is something you can bring to appointments with your prescriber as part of a real picture of how your journey is going.

General educational guidance — including NHS dietary advice — is a great starting point, but individual responses vary. Always follow the specific guidance your prescriber or doctor has given you, especially around calorie targets or any medical conditions that affect your diet.
