FIGHT WEEK NUTRITION: THE 7-DAY EAT DOWN

The week leading into a fight is where nutrition planning either delivers a sharp, ready athlete to the scale or sabotages them. For a moderate cut (4-6 lb over fight weight), the structured 7-day protocol below has been used by countless professional fighters and is the safest evidence-supported approach.

Days 7-5 out (Sunday-Tuesday for a Saturday weigh-in): hydrate aggressively. Drink 7-9 liters of water per day with electrolytes (sodium 3-5g, potassium 2-4g). This sounds like a lot but it is intentional. Flooding the body with water primes the kidneys to flush efficiently when you cut intake later. Eat normal training volume of calories (around maintenance), but reduce sodium gradually from day 7 and eliminate it by day 5. Protein stays high (2g/kg+). Carbs moderate.

Days 4-3 out (Wednesday-Thursday): cut water to 4-5 liters per day. Eliminate residual sodium fully. No salted nuts, no soy sauce, no processed foods. Keep training light. Continue high protein. Reduce carbs further to deplete glycogen (each gram of glycogen holds 3-4g of water).

Day 2 (Friday, day before weigh-in): cut water to 1-2 liters total, sipped throughout the day. No food after dinner. Sauna or hot bath sessions if needed to drop the last 1-2lb. Limit to 20 minutes at a time, never to dizziness, with a friend present.

Weigh-in day (Saturday morning): no water, no food, weigh in dehydrated. Step on the scale within the legal weight. Post-weigh-in rehydration is critical and must be deliberate. Sip electrolyte drink slowly (Pedialyte or similar) over 1-2 hours, not chugged. Small meal of easily digestible carbs and modest protein (rice and chicken, or a bagel with peanut butter) 1-2 hours after weighing in. Resume normal eating across the rest of the day, hitting your fight-day breakfast portions by dinner.

The morning of the fight: a familiar breakfast you have eaten 100 times in training. Eggs, rice, fruit, 3-4 hours before the bout. Light snack 90 minutes out: banana, rice cake, or sports drink. Nothing experimental, nothing new, nothing you have not tested in training camp.

This protocol is for moderate cuts at 4-6 lb. For larger cuts (8-12+ lb) you need professional supervision: a sports nutritionist and ideally a medical team monitoring your hydration and electrolyte status. Aggressive cuts have killed fighters. They are not a place to improvise.
