Fight Week Meal Plan: What to Eat Before Weigh-In

Fight week nutrition is not about losing weight — that should already be done. Fight week is about arriving at weigh-in as light as possible while keeping enough fuel in the tank to perform. The decisions you make about food in the final 7 days can either preserve or destroy the work of the previous 8-12 weeks.

7-5 days out: carb management

At this stage, you should be within 2-3kg of your target weight if your diet cut phase went to plan. The goal now is to reduce stored glycogen (and its associated water) without crashing energy levels.

Reduce carbohydrate intake to approximately 50-100g per day. Each gram of stored glycogen binds 3-4g of water, so depleting glycogen stores can account for 1-2kg of scale weight. Focus on lean protein, non-starchy vegetables, and small amounts of healthy fats. Egg whites, chicken breast, white fish, and leafy greens become your staples.

Protein stays high — at least 2.0g per kilogram of target bodyweight. This is not the time to reduce protein. You are already in a caloric deficit and your body needs amino acids to preserve muscle tissue.

4-3 days out: low residue

Switch to a low-residue diet to reduce gut content. This means cutting out fibre: no whole grains, no raw vegetables, no fruit skins, no legumes. The gut typically holds 1-2kg of food and waste material at any given time. A low-residue diet flushes most of this over 2-3 days.

Meals become simple and easily digested: white rice (small portions), boiled chicken, white fish, scrambled eggs, clear broth. Drink water normally at this point — do not start restricting fluid yet.

2-1 days out: water taper

This is where the water manipulation begins, if any is needed. A gentle taper means reducing water intake to roughly 50% of normal on the second-to-last day, then to sipping only on the final day. Combined with the glycogen depletion and low-residue diet, this should be enough to drop the final 1-1.5kg.

Food portions shrink further. You are eating for protein only at this point — small, easily absorbed meals. Avoid anything salty, anything carbonated, and anything that might cause bloating or water retention.

Weigh-in morning

For same-day weigh-ins (judo, wrestling, BJJ), keep the morning simple. Weigh yourself at home first. If you are on weight, sip water as needed to stay comfortable. If you are slightly over, a warm shower or light movement may shed the last few hundred grams through insensible water loss.

For 24-hour weigh-ins (MMA, boxing), the strategy is more aggressive because you have time to rehydrate. But the principle is the same: minimal food, minimal water, weigh in, then immediately begin the refuelling process.

Post weigh-in refuel

What you eat after weighing in is as important as what you ate before. The priority is rehydration and glycogen replenishment, in that order.

Start with an electrolyte drink — water alone is not enough because you have depleted sodium and potassium. Sip steadily rather than chugging, which can cause nausea. Within the first hour, introduce easily digestible carbohydrates: white rice, white bread, bananas, honey. Add moderate protein but avoid high-fat foods which slow gastric emptying.

For same-day weigh-ins, you may only have 2-4 hours before your first match. Eat small, frequent, carb-rich snacks rather than one large meal. A banana with honey, a rice cake with jam, or a sports drink are better choices than a full plate of pasta that will still be sitting in your stomach during the first round.
