1. Broccoli (GI: ~15)
High fibre, low GI, and full of compounds that support liver detox and gut health. Plus, itโs 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: itโs gentle on sensitive stomachs.
Best prep:
Stir into omelettes, soups, or sautรฉ with a little lemon and olive oil.
3. Courgette (Zucchini) (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.

Raw with dip, grated into salads, or lightly roasted with herbs.

Sweet, hydrating, and bursting with vitamin C. These beauties are a dream for adding crunch and colour to meals.

Raw in wraps or salads, or roasted whole and stuffed with quinoa or lentils.

Best prep:
Cauli rice, roasted florets, or blended into creamy soups.
8. Onions (GI: ~10)
Yes, theyโre VERY low GI! And they add serious flavour. Just go easy on portion sizes if youโre sensitive.

Sautรฉed in olive oil, caramelised, or blended into dressings.

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.

Crushed and sautรฉed into everything. Bonus points for roasted garlic paste.
12. Lettuce (All types โ GI: ~10)
Not exciting on its own, but layered right it adds crunch, volume, and freshness. Also super easy on sensitive stomachs.

As a salad base or wrap alternativeโcos, butter, and gem are all great picks.

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 drizzleโchefโs 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 youโre eating less, adding bulky veg can make tiny portions feel more satisfyingโwithout adding bloat or blood sugar spikes.
