This is for fighters in the final week who want food that is easy to digest. The goal is to reduce gut weight while keeping training steady.
Key takeaways
- A low-fibre approach can help some fighters feel lighter because less fibre can mean less food sitting in the gut.
- Lowering carbs can reduce glycogen and the water stored with it, which lowers scale weight.
- Low-fibre is usually short term, for a few days only.
- Food should stay simple and repeatable in fight week.
- Water changes, if needed, should be structured and timed close to weigh-in.
- Extreme dehydration should not be your main plan.
One simple guide with the exact fight week structure used with elite fighters.
What “low-fibre” means
Fibre is the part of plant foods that helps digestion. More fibre can increase temporary gut weight for some fighters. Reducing fibre for 3–5 days can reduce this.

FAQs
Do I need low-fibre for the whole week?

Will low-fibre make me lose fat?
No. It mainly affects gut weight, not body fat.

Yes, but keep portions small and simple if digestion is sensitive.
