- ✓Fight week is not a diet week — the fat-loss work should already be done.
- ✓Carbs taper pre-weigh-in and reload after: glycogen holds water, so timing is the tool.
- ✓Low fiber in the final days: gut contents are real pounds on the scale.
- ✓Post-weigh-in: fluids with electrolytes first, then carb-forward familiar meals.
- ✓The champion's rule: nothing new in fight week. Boring is a performance enhancer.
Fight-week eating is deliberately boring: familiar foods only, protein steady (to protect muscle), carbohydrates tapered early in the week then reloaded after the weigh-in, fiber and sodium reduced in the final days (both add gut and water weight), and hydration following the load-taper protocol. After the weigh-in, the job flips to rehydration and glycogen refill: electrolyte fluids, then rice, potatoes, fruit and lean protein in repeated moderate meals. The rule of the week: nothing new — no new foods, supplements or restaurants.
Fight-week food photos disappoint everyone: rice, eggs, fish, bananas, water bottles labeled with times. The glamour is precisely the point — by fight week, every interesting decision should already be made.
The week's one trick The centerpiece is the carbohydrate see-saw. Early week, carbs taper down — not for calories, but because every gram of stored glycogen locks water alongside it. Lighter glycogen, lighter body, easier weigh-in. Then, the moment the scale is satisfied: reload. Rice, potatoes, fruit — steady moderate meals, and the muscles refill with fuel and water in time for the bell.
Alongside it: fiber drops in the final days (gut contents are pounds; let them leave and don't restock until after the scale), sodium eases down with the water taper, and protein never moves — muscle is not part of the negotiation.
After the scale Rehydration is a discipline, not a celebration: electrolyte fluids in repeating doses beat one heroic gallon (which mostly becomes urine and nausea). Then meals — familiar, carb-forward, low-fat, spread across the evening. The famous weigh-in burger is a photo op; the fighters who live on it fight like it.
The prime directive Nothing new in fight week. No new supplement, cuisine, or restaurant experiment. The gut is part of the fight team, and it doesn't like surprises on deadline.
Fight week eating is a logistics operation with a fork.

FAQ
Why do fighters eat low fiber before a weigh-in?+
Digestive contents weigh real pounds. Dropping fiber for the last 2–3 days empties the gut gradually — weight that returns harmlessly with post-weigh-in meals. It's the cheapest, safest weight a fighter can lose.
What do boxers eat the morning of a fight?+
Familiar, carb-forward, moderate: oats, rice, eggs, fruit — 3–4 hours before the walk, sized to be gone from the stomach by fight time. A light top-up (banana, honey, a sports drink) can come 60–90 minutes out.
Do fighters eat junk food after the weigh-in?+
The famous burger photos are theater. Smart camps rehydrate with electrolytes first, then rebuild with easy-digesting carbs and lean protein across several meals. A grease bomb the night before a fight is a gamble the stomach collects on in round three.
