What to Eat on Mounjaro or Wegovy

GLP-1 medications do not require strict dieting, but the medication works better when you eat well. The goal is not restriction but rather eating foods that work with the medication and support sustained weight loss. This guide focuses on working with the medication, not against it.

The Basic Principle: Prioritise Protein

Protein is your best friend on a GLP-1 medication. Protein keeps you feeling full longer, builds muscle (which you want to preserve during weight loss), and has a higher thermic effect (meaning your body burns more calories digesting it). Aim to include protein at every meal. This does not mean endless chicken—variety matters.

Breakfast Ideas

• Eggs: boiled, scrambled, or omelette with vegetables
• Greek yoghurt with berries and a small amount of granola
• Cottage cheese with fruit
• Smoked salmon and cream cheese on whole grain toast
• Protein smoothie with banana, berries, protein powder, and almond milk

Lunch Ideas

• Grilled chicken breast with roasted vegetables
• Salmon with sweet potato and broccoli
• Turkey wrap with hummus and vegetables
• Lentil soup with wholemeal bread
• Tuna salad with olive oil dressing

Dinner Ideas

• Lean beef or lamb with roasted root vegetables
• Baked white fish with asparagus and lemon
• Chicken stir-fry with brown rice
• Vegetable curry with chickpeas and basmati rice
• Turkey meatballs with tomato sauce and pasta

Snack Ideas (When Hungry)

• Nuts and seeds (small handful)
• Cheese and apple
• Hard-boiled egg
• Plain yoghurt with berries
• Hummus with vegetables

Foods to Reduce

Fatty and sugary foods are not forbidden but often trigger nausea or discomfort on GLP-1 medication. Reduce: high-fat pastries, fried foods, heavy cream sauces, sugary drinks and desserts, alcohol (especially on injection day), and very spicy foods. You may find these foods no longer appeal anyway—the medication often naturally reduces cravings for unhealthy foods.

Hydration Is Critical

Drink far more water than you normally would. Most side effects improve with better hydration. Many people underestimate how much water they need. Aim for 2-3 litres daily, more if you exercise. Drink water throughout the day, not just with meals. Herbal teas count towards hydration—chamomile, peppermint, and ginger tea are especially good.

Eating Out While on GLP-1

You can still eat out. Choose restaurants that offer protein-focused meals: steakhouses, fish restaurants, Mediterranean restaurants. Order smaller portions or share a main course. Ask for sauces on the side. Do not force yourself to finish a meal—you will be full much sooner than before. Restaurant meals are often higher in fat and salt, which can trigger nausea, so stick to simpler dishes.

Meal Size and Frequency

Eat when you are hungry. With GLP-1, hunger becomes accurate: you eat because you are hungry, not because the clock says mealtime. Some people do well with three smaller meals. Others prefer four or five small meals. Listen to your body. Do not force yourself to eat large meals or specific meal times—the medication has adjusted your appetite regulation, so trust it.

The Role of Exercise

Exercise enhances weight loss but is not essential. Walking is excellent and aids digestion. Strength training preserves muscle during weight loss. Swimming and yoga are gentle and effective. Exercise does not need to be intense—consistent, regular activity is more important than occasional intense workouts. Even 20-30 minutes of walking daily makes a significant difference.

Food Journals and Tracking

Some people find food journaling helpful (noting what they eat and how they feel). Others do not need it. You do not need to count calories obsessively—with GLP-1, hunger naturally keeps you at the right amount. But tracking can reveal patterns (which foods trigger nausea, which foods work well for you).

The Bottom Line

Eat protein-rich, nutrient-dense foods. Prioritise vegetables and whole grains. Reduce fatty and sugary foods (not forbidden, just less appealing). Drink lots of water. Eat when hungry, stop when full. Exercise regularly but not obsessively. The medication is doing the hard work; your job is to eat well and move your body. You do not need to be perfect or follow a strict diet. Simple, healthy eating combined with the medication produces significant weight loss.
