What Should I Eat Before a Jiu Jitsu Competition?

Fueling your body properly before a jiu jitsu competition is just as important as your training. The right nutrition can enhance your performance, while poor choices can leave you feeling sluggish or nauseous. Here’s a comprehensive guide to help you optimize your pre-competition meals. Including a water-cut guide if you are actually needing to lose weight prior to the competition. However, know that water cuts (though you can lose 5-8 lbs quite easily) can diminish your performance, especially if you are not hydrated before the competition.

1. Understand Your Body’s Needs

Jiu jitsu competitions demand a combination of endurance, strength, and mental focus. To meet these demands, you need a balanced diet that provides:

• Carbohydrates: Your body’s primary source of energy.

• Protein: Essential for muscle repair and sustained energy.

• Fats: A secondary source of energy that helps with longer-duration efforts.

• Hydration: Proper hydration is critical for muscle function and mental clarity. Maybe one of the most important and overlooked factors here.

2. The Week Leading Up to the Competition

In the days before your competition, your focus should be on maintaining energy levels and avoiding foods that may cause digestive issues. Follow these tips:

• Increase Complex Carbohydrates: Foods like brown rice, sweet potatoes, for sustained energy.

• Proteins: Include chicken, fish, eggs, or beef. If you have dietary restrictions, make sure you are getting complete amino-acid profiles in your various other protein sources

• Healthy Fats: Add avocado, nuts, animals fats, or olive oil to your diet to support overall energy needs.

• Stay Hydrated: Drink plenty of water throughout the week. Aim for at least half your body weight in ounces per day, and consider adding an electrolyte drink to replenish minerals lost during training. The more you sweat, the more electrolytes you are losing.

Avoid trying new foods during this time—stick to what your body is used to, so there are no surprises on competition day.

3. The Day Before the Competition

The night before your competition, you want to load up on carbohydrates to ensure your glycogen stores are full. Here’s what a sample dinner might look like:

• Main Dish: Grilled chicken or eggs (something easily digestible)

• Side: Steamed vegetables (broccoli, carrots, or green beans) not too much fiber

• Carbohydrate: A serving of rice or sweet potato, again something easily converted into glucose, any type of starch will do

• Hydration: Water and electrolytes

Avoid heavy, greasy, or overly spicy foods, as these can upset your stomach or make you feel bloated.

4. Competition Day Nutrition

Your competition day meal strategy depends on the timing of your match. The goal is to eat something that provides energy without making you feel sluggish or weighed down. High protein or high fats take much longer to digest, so make sure you eat protein right away.

If Your Match Is in the Morning:

• Eat a light breakfast 2-3 hours before your match.

• Examples:

  • A bowl of oatmeal with a banana and a drizzle of honey

  • Whole-grain toast with almond butter and a small piece of fruit

  • A smoothie made with protein powder, almond milk, a banana, and spinach

• Hydrate with water or an electrolyte drink

If Your Match Is in the Afternoon:

• Eat a substantial breakfast and a light snack closer to your match.

• Breakfast Example:

  • Scrambled eggs with avocado and a side of whole-grain toast

  • A small bowl of Greek yogurt with granola and fresh berries

• Snack Example:

  • A banana with peanut butter

  • A handful of almonds and a rice cake

Avoid heavy meals right before your match, as digestion diverts energy.

5. Foods to Avoid

Some foods can hinder your performance by causing digestive discomfort or energy crashes. Avoid these:

• Greasy or Fried Foods: Hard to digest and can cause bloating.

• High-Sugar Foods: Candy, pastries, or sugary drinks can lead to energy spikes and crashes.

• Dairy: For some, dairy can cause stomach issues or excess mucus production.

• Excess Fiber: While fiber is usually good, too much before a competition can lead to bloating or gas.

6. Hydration Tips

Hydration is critical, especially if you’ve been cutting weight. Drink water consistently throughout the day, but avoid chugging large amounts right before your match. Consider sipping on an electrolyte drink to replenish sodium, potassium, and magnesium lost through sweat.

7. Post-Competition Recovery

Once your match is over, your focus shifts to recovery. Eat a meal rich in protein and carbohydrates within two hours to replenish glycogen stores and aid muscle repair. Examples include:

• A chicken and rice bowl with vegetables

• A protein shake with a banana

Water Cut Chart

If you are doing a water cut, except to lose 5-8 lbs of water weight. Know the severity and risk of dehydration. If you are cutting water it is imperative to hydrate as quickly as you can with salts and water immediately after the weigh in. If this is your first competition, I would highly suggest to avoid a water cut and compete at a higher weight if you cannot make your weight class.

Final Thoughts

Proper nutrition is an often-overlooked aspect of jiu jitsu competition prep. By eating the right foods at the right times, you’ll maximize your energy levels, mental focus, and overall performance. Experiment during training to find what works best for your body, so there are no surprises on competition day. Remember, good preparation starts long before you step onto the mats—fuel your body like the athlete you are.
