Fibremaxxing: how to get 30g of fibre a day without the bloating

Quick answer: Fibremaxxing means deliberately eating more fibre, and most adults should aim for about 25–30 g a day. Get there slowly (add about 5 g a week), drink more water, and use everyday foods like lentils, chickpeas, beans, oats, whole fruit, vegetables, flaxseed and whole grains. Going from low to high overnight is what causes bloating.

Fibremaxxing is one of 2026's biggest food trends, with hundreds of millions of views on social media. Unlike most viral trends, this one is actually backed by solid science. Most people eat far less fibre than they need, and fibre is linked to better digestion, steadier blood sugar, lower cholesterol and feeling full for longer.

What fibre actually does

• Feeds your gut bacteria. They turn fibre into compounds that help keep the gut lining healthy.
• Slows sugar absorption, so you get fewer energy crashes after meals.
• Keeps you full, which makes it easier to avoid snacking.
• Keeps you regular. It's the simplest fix for mild constipation.

Easy fibre wins from everyday foods

These are approximate amounts, but they show how quickly it adds up:

• 1 cup cooked kidney beans or chickpeas: about 12–13 g
• 1 cup cooked lentils: about 15 g
• 1 cup raspberries: about 8 g
• 2 tablespoons flaxseed: about 5 g
• ½ cup oats: about 4 g
• 1 apple or pear, with the skin: about 4–5 g
• 2 slices wholegrain bread: about 4–6 g
• 1 small bowl roasted chickpeas: about 5–6 g

A sample 30g day

• Breakfast: porridge oats with 1 tbsp flaxseed and a fruit (about 10 g)
• Lunch: lentil soup, a big salad and wholegrain bread (about 12 g)
• Snack: roasted chickpeas or an apple (about 5 g)
• Dinner: a bean chilli or chickpea stew with a vegetable (about 8–10 g)

How to avoid bloating

1. Go slow. Add one high-fibre food per week, not five in one day. Your gut bacteria need time to adjust.
2. Drink more water. Fibre pulls water into the gut. Without enough fluid it can make constipation worse.
3. Soak and cook legumes well. Soaking dried beans overnight, rinsing canned ones, and cooking them with cumin, fennel or ginger makes them easier to digest.
4. Chew properly. It sounds basic, but it helps.
5. Spread it out. Fibre across all three meals is much gentler than one huge fibre-heavy dinner.

Food first, powders second

Fibre supplements like psyllium husk can help, but whole foods give you different types of fibre plus vitamins and minerals. Use powders to fill a gap, not as your whole plan.

Who should be careful

If you have IBS, Crohn's disease, a history of bowel obstruction, or you're on medicines that interact with fibre supplements, talk to your doctor or a dietitian first. Some people with IBS do better with specific, lower-FODMAP fibre sources.
