Fight Week Nutrition
A complete day-by-day plan from Monday through fight night — what to eat, when to eat, and how to arrive at the ring fully fueled
Fight week is the culmination of months of training. Everything comes down to executing a precise plan: making weight safely, rehydrating effectively, and arriving at the ring with your body fueled and your mind sharp. This guide walks through each day with specific meals, fluid targets, and practical advice tailored for Kun Khmer fighters competing in Cambodia and internationally.
This plan assumes a Friday weigh-in with a Saturday fight. Adjust the timeline if your weigh-in and fight are on different days. For same-day weigh-ins (common in domestic Cambodian events), the water cut must be much more conservative — no more than 1.5-2% of body weight — since rehydration time is limited. See the weight cutting guide for the full 4-week protocol leading up to this week.
Monday Through Friday
Pre-fight nutrition plan with daily targets
Monday
Focus: Final hard training session — fuel for performance
Water: 45-50 ml/kg (3.2-3.5L for 70kg fighter)
Breakfast (6:00 AM)
550 kcal
Bai sach chrouk — 1.5 cups rice, 120g grilled pork, pickled vegetables
Post-training (9:30 AM)
380 kcal
Protein shake with banana and coconut water
Lunch (12:00 PM)
550 kcal
Samlor korko with rice — lighter portion than usual training days
Snack (3:00 PM)
320 kcal
Small portion of rice with 2 boiled eggs
Dinner (6:30 PM)
480 kcal
Steamed fish with ginger, 1.5 cups rice, steamed vegetables
Monday is typically the last day of meaningful training. Eat enough to fuel a quality session but begin the slight caloric reduction that continues through the week. If you are on weight, eat normally. If you need to lose 1-2 kg, maintain a moderate deficit.
Tuesday
Focus: Light training — technique and visualization only
Water: 45 ml/kg (3.15L for 70kg fighter)
Breakfast (7:00 AM)
400 kcal
Kuy teav with lean pork — light broth, moderate noodles
Mid-morning (10:00 AM)
150 kcal
Fresh fruit — papaya, banana
Lunch (12:30 PM)
450 kcal
Grilled chicken with rice (1 cup) and cucumber salad
Snack (3:30 PM)
280 kcal
Rice porridge (bobor) with chicken — small bowl
Dinner (6:30 PM)
420 kcal
Steamed fish with vegetables, 1 cup rice
Begin reducing carbohydrate portions. Replace high-volume carb meals with protein-focused dishes. Training should be limited to light pad work, shadow boxing, and visualization. Save energy — your body is a weapon that needs to be charged, not depleted.
Wednesday
Focus: Water reduction begins — light movement only
Water: 25 ml/kg (1.75L for 70kg fighter) — water cut begins
Breakfast (7:00 AM)
380 kcal
Scrambled eggs (3) with a small portion of rice, sliced tomato
Mid-morning (10:00 AM)
160 kcal
Small handful of almonds or cashews
Lunch (12:30 PM)
350 kcal
Grilled chicken breast (150g) with steamed vegetables — no rice
Snack (3:30 PM)
100 kcal
Apple or small banana
Dinner (6:00 PM)
320 kcal
Lean protein (grilled fish or chicken, 150g) with green vegetables
Water intake drops significantly. Carbohydrates are minimized to deplete glycogen stores and release bound water. You will feel hungry and possibly irritable — this is normal. Keep yourself occupied with light stretching, visualization, and rest. Avoid heavy physical activity. Monitor urine color — it will darken, but it should not become brown.
Thursday
Focus: Deep water cut — rest and prepare mentally
Water: 15 ml/kg (1.05L for 70kg fighter) — sipping only
Breakfast (8:00 AM)
280 kcal
2 boiled eggs, small piece of chicken breast
Lunch (12:00 PM)
250 kcal
Small portion of grilled fish with leafy greens (no dressing)
Dinner (5:00 PM)
180 kcal
Small protein-only meal — 100g chicken or fish
This is the hardest day. Fluid intake is minimal and food is sparse. Stay in a cool environment to minimize sweating. Do not train. A short walk is acceptable but avoid anything that increases fluid loss beyond what the protocol calls for. If fighting Saturday, this is the peak of the water cut. Weigh yourself in the evening — you should be within 1-1.5 kg of your target.
Friday
Focus: Make weight, then refuel immediately
Water: Sips only until weigh-in, then aggressive rehydration
Before weigh-in
0 kcal
Nothing or small sips of water if absolutely necessary
Immediately after weigh-in
80 kcal
Electrolyte drink (ORS), coconut water — begin sipping immediately
1-2 hours post weigh-in
400 kcal
Rice porridge (bobor) with chicken, banana, more electrolyte drinks
3-4 hours post weigh-in
550 kcal
Bai sach chrouk or rice with grilled chicken — moderate portion
6-8 hours post weigh-in
600 kcal
Amok trey with rice — familiar, balanced meal
Evening snack
250 kcal
Fruit, yogurt, or light carbohydrate snack
The moment you step off the scale, your sole focus shifts to rehydration and refueling. Sip fluids steadily — do not chug large volumes as this can cause vomiting and delay absorption. Prioritize electrolytes in the first 2 hours, then transition to balanced meals. By evening you should have consumed at least 3-4 liters of fluid. You will not fully recover all lost fluid, but you can regain 70-80% if you are disciplined with the protocol.
Weigh-In Day Protocol
Weigh-in day is the culmination of the entire weight cut. Your only job before stepping on the scale is to be at or under your target weight. Everything else — rehydration, refueling, rest — comes after.
Before the Scale
- Wake up early and check your weight on a reliable scale
- If you are on weight, take small sips of water to stay comfortable
- If you are 0.5-1 kg over, a hot bath or light exercise in warm clothing can shed the last bit
- Arrive at the weigh-in venue early to avoid stress
- Weigh in wearing as little as permitted by the rules
- If you miss weight, most sanctioning bodies allow a 1-2 hour window to try again
Immediately After the Scale
- Begin sipping an electrolyte solution — have it prepared in advance
- Your corner team should have your rehydration supplies ready at the venue
- Do not eat solid food for the first 30-60 minutes — focus on fluids
- Move to a comfortable location where you can eat and rest
- Follow the rehydration protocol from the weight cutting guide
- Avoid celebrating with alcohol — your body needs every drop of fluid for recovery
Day-of-Fight Nutrition
Precise timing around your scheduled fight time
4-5 hours before fight
Pre-fight meal
A moderate, familiar meal high in carbohydrates with moderate protein and low fat. White rice with grilled chicken or fish. Avoid anything heavy, spicy, or unfamiliar. This is not the time to experiment.
1.5 cups rice, 120g grilled chicken, small portion of steamed vegetables. ~520 kcal.
2-3 hours before fight
Light snack
A small carbohydrate-rich snack to keep blood sugar stable. Easy to digest and quick to clear the stomach.
A banana with a small amount of honey, or a piece of white bread with jam. ~150 kcal.
1 hour before fight
Final hydration and energy
Small sips of water or electrolyte drink. Some fighters take a small amount of honey or a glucose gel for a quick energy boost. Keep it minimal — a full stomach impairs breathing and movement.
200ml water or electrolyte drink, optional tablespoon of honey.
30 minutes before fight
Nothing
Stop all food and fluid intake. Focus entirely on warm-up, mental preparation, and the Twai Kru ceremony. Your body has the fuel it needs — trust the preparation.
Warm-up, visualization, and pre-fight rituals only.
Between rounds
Water and glucose (if needed)
Small sips of water during the corner break. Some fighters take a sip of electrolyte drink or a glucose rinse (swishing a sugary drink and spitting it out) to signal energy availability to the brain without adding fluid to the stomach.
A few sips of water. Glucose rinse if fatiguing.
Immediately after the fight
Begin recovery nutrition
Within 30 minutes of the fight ending, begin consuming fluids and simple carbohydrates. A protein shake with banana is ideal if available. Coconut water for electrolytes.
Protein shake, banana, 500ml coconut water. ~350 kcal.
Post-Fight Recovery Meal (1-2 Hours After)
After the adrenaline subsides, eat a full, balanced meal. Your body has been through extreme stress and needs calories, protein, carbohydrates, and hydration. Many Cambodian fighters celebrate with a favorite dish — lok lak, amok trey, or bai sach chrouk. This is the one meal of the week where you can eat freely. You have earned it. Drink plenty of fluids and continue rehydrating through the evening. If you sustained any cuts or significant trauma, prioritize protein-rich foods to support healing.
Mental Aspects of Fight-Week Eating
The psychological dimension of nutrition during the hardest week
Accept discomfort as temporary
Fight week hunger and dehydration are temporary. Remind yourself that thousands of fighters have gone through this process successfully. The discomfort peaks on Thursday/Friday and ends completely after you step on the scale. Reframe the discomfort as part of your warrior preparation — Kun Khmer fighters have been making sacrifices before battle for centuries.
Maintain your routine
Eat at the same times you normally eat, even if the portions are smaller. Keep your daily schedule as normal as possible. The structure of routine provides psychological stability when your body is under stress. Wake up at the same time, go to the gym at the same time (even if just to stretch), and maintain your evening habits.
Separate food from emotion
Fight week is not the time to eat for comfort, boredom, or stress relief. View food purely as fuel and medicine. Each meal has a specific purpose — to maintain muscle, to support recovery, or to prepare for the scale. This disciplined mindset is a core part of the fighter's mentality and extends beyond the kitchen into the ring.
Manage irritability
Caloric restriction and dehydration cause irritability — this is a physiological response, not a character flaw. Warn your family, training partners, and friends that you may be short-tempered during the cut. Avoid making important decisions or having difficult conversations during the final 48 hours. Use meditation, breathing exercises, or listening to music to manage your emotional state.
Visualize the post-weigh-in meal
Having a specific meal planned for after weigh-in gives you something to look forward to and provides a concrete endpoint to the restriction. Many experienced fighters have a ritual first meal — a favorite dish that they associate with the relief and satisfaction of making weight. In Cambodia, bai sach chrouk or a bowl of kuy teav are popular choices.
Trust the process
If you have followed the 4-week protocol and your weight has been tracking according to plan, trust that the process will work. Anxiety about the scale is natural, but panicking and doing something drastic (like an extra sauna session or skipping water entirely) is more likely to hurt your performance than help it. Stick to the plan.
“The fight is not just in the ring. The fight begins the moment you commit to a weight class and start preparing your body. A disciplined fighter controls what they eat, when they eat, and how they think about food. This discipline is the same discipline that keeps your guard up in round five when your arms are burning. It is all connected.”
