1. Broccoli (GI: ~15)
High fibre, low GI, and full of compounds that support liver detox and gut health. Plus, it’s surprisingly filling once steamed or roasted.
Best prep:
Roasted with olive oil and garlic, or chopped raw into slaws and salads.
2. Spinach (GI: <15)
Packed with iron, magnesium, and antioxidants, spinach wilts down beautifully into any meal. Bonus: it’s gentle on sensitive stomachs.
Best prep:
Stir into omelettes, soups, or sauté with a little lemon and olive oil.
3. Courgette (Zucchini) (GI: ~15)
Light, easy to digest, and great for adding bulk without heaviness. Courgette noodles? Banging.
Best prep:
Sliced into stir-fries, spiralised, or grilled and layered into bakes.
4. Rocket (Arugula) (GI: <15)
Peppery and refreshing, rocket is a fab base for salads and sandwiches. It’s light but still gives you that ‘real meal’ feeling.
Best prep:
Toss with balsamic and olive oil, or pile on top of soups and pizzas.

5. Carrots (Raw GI: ~16, Cooked GI: ~35)
Crunchy, colourful, and rich in fibre. Raw is best for keeping the GI low and your teeth busy.
Best prep:
Raw with dip, grated into salads, or lightly roasted with herbs.
6. Bell Peppers (GI: ~15)
Sweet, hydrating, and bursting with vitamin C. These beauties are a dream for adding crunch and colour to meals.
Best prep:
Raw in wraps or salads, or roasted whole and stuffed with quinoa or lentils.
7. Cauliflower (GI: ~15)
Low carb, high fibre, and great for gut health. It’s also a low-GI chameleon—mash it, rice it, roast it, love it.
Best prep:
Cauli rice, roasted florets, or blended into creamy soups.
8. Onions (GI: ~10)
Yes, they’re VERY low GI! And they add serious flavour. Just go easy on portion sizes if you’re sensitive.
Best prep:
Sautéed in olive oil, caramelised, or blended into dressings.

9. Cabbage (GI: ~10)
Bulky, affordable, and fabulous for digestion when cooked properly. (And no, it doesn’t have to cause gas.)
Best prep:
Shredded into stir-fries, slaws, or roasted until crispy.
10. Cucumber (GI: ~15)
Technically a fruit, but we’re letting it sit at the veg table. It’s hydrating and bloat-friendly.
Best prep:
Raw in salads, sliced with hummus, or blended into a refreshing yoghurt dip.
11. Garlic (GI: ~10)
Tiny but mighty. Low GI and gut-friendly in moderation, garlic also acts as a natural prebiotic to feed your good gut bugs.
Best prep:
Crushed and sautéed into everything. Bonus points for roasted garlic paste.
12. Lettuce (All types – GI: ~10)
Not exciting on its own, but layered right it adds crunch, volume, and freshness. Also super easy on sensitive stomachs.
Best prep:
As a salad base or wrap alternative—cos, butter, and gem are all great picks.

13. Radishes (GI: ~15)
Crispy, peppery, and surprisingly satisfying. These are underrated little gems that help with digestion and keep your plate exciting.
Best prep:
Sliced raw in salads, or roasted whole with a sprinkle of salt and paprika.
GLP-1-Friendly Tips to Maximise Your Low GI Vegetables Game
- Pair with protein and healthy fat: Think roasted veg with grilled chicken and a tahini drizzle—chef’s kiss and blood sugar friendly.
- Cook to reduce bloating: Raw veg can be harder to digest, especially early on in GLP-1 treatment. Steaming, roasting or stir-frying makes them gentler.
- Add herbs and acids: A squeeze of lemon, a dash of vinegar or some fresh herbs can lift a basic veg dish into something lush (and digestion-boosting!).
- Use them to stretch small meals: Even when you’re eating less, adding bulky veg can make tiny portions feel more satisfying—without adding bloat or blood sugar spikes.
