What to Eat for Fat Loss on a GLP-1 Diet

When appetite is reduced and portions shrink naturally, the most common nutritional gap is protein. Eating enough protein — generally discussed in the range of around 1.2–1.6 g per kg of body weight, though individual needs vary — helps your body hold on to lean muscle as fat is lost. Speak with your prescriber or a registered dietitian about what level is right for you.

Foods that tend to work well

• Lean proteins: chicken breast, turkey, fish, eggs, low-fat Greek yogurt, cottage cheese, tofu and legumes all provide protein in compact portions.
• Fibre-rich vegetables: leafy greens, courgette, broccoli, and cucumber are low in calories and gentle on a sensitive stomach.
• Slow-release carbohydrates: oats, brown rice, sweet potato, and lentils offer steady energy without large blood-sugar spikes.
• Healthy fats in moderation: avocado, olive oil, and nuts support satiety, but are calorie-dense, so smaller amounts are usually sensible.

Foods many people find harder to tolerate

Greasy, heavily processed, or very sugary foods are commonly reported to worsen nausea and digestive discomfort on GLP-1 medicines. Many people find it helpful to scale these back, though individual tolerance varies. For practical guidance on which foods tend to support a GLP-1 weight-loss diet, see our dedicated guide.

Balancing calories and fat loss

Fat loss happens when you consistently eat fewer calories than your body uses — a calorie deficit is the underlying driver of fat loss on any diet. GLP-1 medicines make this easier for many people by reducing appetite, but tracking what you eat remains valuable, particularly to ensure you're hitting protein targets. For a closer look at how calories and fat loss relate, our explainer covers the key principles. You may also find it useful to explore building a structured weight-loss diet plan that fits around your GLP-1 journey.

Keeping tabs on protein and calories when you're eating less than usual is much easier with a tool built for it. GLP Trackr's AI photo-scan feature lets you point your camera at a meal and get an instant breakdown of calories, protein, and macros — no manual searching needed. On days when appetite is low and meals are small, this takes most of the friction out of logging.

Alongside food logging, you can set daily protein and calorie targets, then see at a glance how close you are by the end of the day. The meal plan and recipe library includes GLP-1-friendly options built around protein and easy-to-digest ingredients, so you always have ideas ready even when food noise is low.

GLP Trackr also ties your food data to your wider progress — weight, energy, and mood — so over time you can spot what eating patterns genuinely move the needle for you. That kind of personalised insight is difficult to build without consistent tracking.

If you have specific questions about calorie targets or what macros are right for you, always discuss these with your prescriber or a registered dietitian — they can personalise guidance in a way no app can.
