Which vegetables are most useful when you are losing weight?
Non-starchy vegetables are widely regarded as the most helpful category for weight loss: they deliver fibre, vitamins, and minerals while being low in calories relative to their volume, which helps you feel full without crowding out protein.
Leafy greens
Spinach, kale, rocket, and other dark leafy greens are among the most nutrient-dense options available. They are very low in calories, provide useful amounts of folate, iron, and magnesium, and blend easily into meals when appetite is low — stirred into scrambled eggs, wilted into soup, or added to a smoothie.
Cruciferous vegetables
Broccoli, cauliflower, cabbage, and Brussels sprouts are high in fibre and contain compounds linked to gut health. They are filling and versatile, though some people on GLP-1 medicines find very fibrous vegetables can feel heavy early in treatment — in that case, steaming or roasting them can make them easier to tolerate.
Watery, crunchy options
Cucumber, courgette (zucchini), celery, and bell peppers have a very high water content, which adds volume to meals and contributes to daily hydration. They also work well as low-calorie snacking choices if appetite returns between meals.
Tomatoes and other salad vegetables
Tomatoes, radishes, and mixed salad leaves are quick to prepare and pair well with lean proteins. Including a variety of colours — reds, greens, oranges, purples — also helps ensure a broad range of micronutrients.
What about starchy vegetables and fruit?
Starchy vegetables such as sweet potato, butternut squash, and beetroot are nutritious and provide slow-release carbohydrates that many people find sustaining — they are not foods to avoid, just worth factoring into your overall calorie and carbohydrate picture. When it comes to the best fruits and vegetables for weight loss together, berries (strawberries, blueberries, raspberries) are a popular choice alongside vegetables because they are relatively low in sugar and high in antioxidants.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.
AI Meal Tracking. Built for GLP 1 Appetites.
Point your camera at any meal and let our AI do the rest. Breakfast, doses, weight, mood all tracked in seconds.
Tracking what you eat — and how it moves your progress
Knowing which vegetables to include is useful; being able to see how your food choices connect to your actual progress is where real insight comes from. GLP Trackr's AI photo-scan food logging is the most direct tool for this: point your camera at a meal or plate and the app estimates calories, protein, and fibre without manual input — genuinely helpful when appetite is low and the last thing you want to do is weigh everything.
Alongside food logging, the app's weight and body tracking charts let you watch how consistent, vegetable-rich eating patterns show up over time in your measurements and weekly progress. The correlation explorer within the insights section can surface patterns — for example, whether days with higher fibre intake tend to align with better progress — using your own data, not generic averages.
Setting a daily fibre target in the app is a practical way to make sure vegetables are a consistent part of each day rather than an afterthought. You can also use the meal plan library for GLP-1-friendly recipe ideas built around the kinds of foods discussed above.
It is worth remembering that progress is rarely linear. Weight can fluctuate week to week for reasons unrelated to food — hydration, hormonal cycles, sleep, and activity all play a role. Tracking the full picture, rather than just the scale, gives a much more honest view of how your journey is going. For more on other approaches people explore alongside lifestyle changes, take a look at our page on hypnotherapy for weight loss or information about statins and weight.
Always follow the guidance of your prescriber or doctor when it comes to your overall plan — they know your full health history and can advise on targets that are right for you specifically. GLP Trackr helps you record what is happening so you can have richer, more informed conversations with them.

Frequently asked questions.
Non-starchy vegetables tend to be most useful: leafy greens such as spinach and kale, cruciferous vegetables like broccoli and cauliflower, and high-water options like courgette and cucumber. They add fibre and nutrients without a high calorie load, which supports progress alongside a GLP-1 medicine.
Both can support a balanced approach. Berries — strawberries, blueberries, raspberries — are popular choices alongside vegetables because they are relatively low in sugar and high in fibre and antioxidants. A varied mix of fruits and vegetables generally provides a wider range of micronutrients.
Starchy vegetables are nutritious and provide slow-release energy. Whether they suit your plan depends on your overall calorie and carbohydrate intake. Your prescriber or doctor is best placed to advise on what is appropriate for your individual situation.
GLP Trackr lets you log meals using AI photo scan, barcode, or manual search, capturing calories, protein, and fibre. You can set a daily fibre target and see how your intake patterns connect to your progress over time in the insights section.
Progress on a weight-loss journey is rarely linear. Hydration, sleep, hormonal changes, and activity levels all influence the scale independently of food choices. Tracking the full picture — not just weight — helps identify what is actually driving results. Speak to your prescriber if you have concerns about your progress.
