After a cut, your gut is stressed. If you eat the wrong foods, you can feel bloated, sick, or get diarrhoea.
Key takeaways
- High-fat food digests slowly and can make you feel heavy or sick after a cut.
- High-fibre food can cause bloating and stomach pain when your gut is sensitive.
- Very sugary foods and fizzy drinks can upset your stomach and leave you feeling worse.
- Heavy dairy can bother some fighters, so keep it light unless you know you tolerate it.
- Start with fluids first, then small meals, then build up.
- Simple carbs plus lean protein is usually the safest first food choice.
One simple guide with the exact fight week structure used with elite fighters.
Why gut problems happen after weigh-in
Your body has been under stress. When you rush food in, especially heavy food, your stomach can struggle.
Foods to avoid (first 6–12 hours)
- Greasy takeaway: burgers, pizza, fried chicken
- Very high fat: creamy sauces, heavy cheese meals, deep fried foods
- High fibre: beans, broccoli, big salads, whole grains
- Very sugary: sweets, pastries, fizzy drinks
- Very spicy: if it normally upsets your stomach
Safer swaps (simple)
- Greasy takeaway → white rice + chicken
- Big salad → small portion veg + pasta or rice
- Fizzy drink → ORS or electrolyte drink + still water
- Heavy steak → fish or chicken
What to eat instead (easy)
- Rehydration drink first (ORS or electrolyte mix).
- Small carbs (rice cakes + honey, cereal, white rice).
- Lean protein (eggs, chicken, fish).
- Build up slowly.
Common mistakes
- Eating a huge meal straight away.
- Trying new foods.
- Using high fat for “extra calories”.
- Ignoring nausea and forcing food down.
Safety warnings
If you cannot keep fluids down, you keep vomiting, or you feel dizzy and unwell, get medical help.
