Fibremaxxing means deliberately eating more fibre — and it's one of the biggest food trends of 2026, with some calling fibre "the new protein." The idea is simple: most people fall short on fibre, and getting more of it supports fullness, gut health and steadier energy. It works, but the trick is ramping up gradually. Here is how to fibremaxx sensibly.
What is fibremaxxing?
Fibremaxxing (often spelt "fibermaxxing") is the habit of consciously pushing your daily fibre higher — through whole foods like vegetables, fruit, beans, lentils, oats, wholegrains, nuts and seeds. It took off alongside the GLP-1 boom, because fibre helps with the fullness and digestion that matter most when appetite is managed. See how it fits a GLP-1 in what to eat on Ozempic.
Why people are doing it
- Fullness. Fibre slows digestion, so you feel satisfied for longer on the same calories.
- Gut health. Fibre feeds the bacteria in your gut. More in the best foods for gut health.
- Steadier energy. It blunts blood-sugar spikes, smoothing out the post-meal slump.
How much fibre?
The general target is around 30g a day, and many fibremaxxers aim higher (40g+). Most people currently get nowhere near it. The full picture is in how much fibre per day. Fibre is a type of carbohydrate — see what are macronutrients.
Best foods to fibremaxx with
| Food | Approx fibre |
|---|---|
| Raspberries (per cup) | ~8g |
| Cooked lentils (per cup) | ~15g |
| Oats (per 100g) | ~10g |
| Black beans (per cup) | ~15g |
| Chia seeds (2 tbsp) | ~10g |
| Avocado (half) | ~7g |
Ramp up slowly — or you'll bloat
The #1 mistake is going from 15g to 45g overnight. That causes gas, bloating and discomfort. Add ~5g every few days, and drink more water as you do — fibre needs fluid to work. Build it, don't binge it.
See your fibre add up
forme tracks fibre alongside your calories and macros, and scores foods against your goals — so fibremaxxing is just watching a number climb, not guesswork.
The bottom line
Fibremaxxing is a genuinely good trend done right: aim for ~30g+ a day from whole foods, ramp up gradually, and drink plenty of water. It is one of the simplest changes with an outsized payoff for fullness and gut health. This is general information, not medical or dietary advice.
