Food choices can make GLP-1 treatment more comfortable and effective. This guide focuses on protein, fibre, fluids and pacing so you feel steady while you adjust to Wegovy or Mounjaro. Use these ideas as a starting point and adapt to your preferences.
Protein first for comfort and fullness
Prioritise protein at meals to protect muscle while you lose weight. Good options include eggs, yoghurt, beans, lentils, tofu, fish and chicken. Aim for a source of protein at each meal and add vegetables or salad alongside whole grains.
If appetite is low, try lighter textures such as Greek yoghurt with berries, soup with beans and vegetables or an omelette with toast.
Fibre and gentle carbohydrates
Fibre supports digestion and helps prevent constipation. Choose oats, whole grain bread, potatoes with skin, brown rice and plenty of vegetables, fruit and pulses. If high fibre foods feel heavy early on, add them in small amounts and increase as comfort improves.
Keep hydration steady through the day. Small sips often are easier than large glasses in one go.
Foods to limit while adjusting to treatment
Large high fat meals, heavy fried foods and very spicy dishes can worsen nausea or reflux. Reduce alcohol, especially near injection day. If coffee increases symptoms, take a smaller amount or move it away from meals.
Simple meal ideas for the first weeks
- Breakfast: porridge with milk and berries, or eggs on whole grain toast.
- Lunch: lentil soup with whole grain bread, or tuna and bean salad.
- Dinner: baked fish or chicken with potatoes and mixed vegetables, or bean chilli with brown rice.
Eat slowly and stop before very full. If you feel unwell, rest and choose light foods until comfortable again.
Planning reviews and staying consistent
Track comfort, appetite and activity. Bring notes to reviews so dose changes are planned around how you feel. For ordering steps see our online guide and for our current prices see Wegovy and Mounjaro.

FAQs
How much should I eat on GLP-1 treatment?
Follow hunger and fullness cues. Aim for balanced meals with protein, fibre and fluids. Avoid very low calories unless directed by a doctor.
What snacks work well?
Fruit with yoghurt, a handful of nuts, whole grain crackers with cheese or hummus and vegetable sticks are simple options.
Can I drink alcohol?
Keep amounts small and avoid drinking near injection day while you adjust, as alcohol can worsen reflux and nausea.
If you would like help planning meals while you adjust, our pharmacists can help you prepare questions for your doctor or dietitian.
