How to Cut Weight for Jiu Jitsu: Complete Guide

January 10, 2025 5 min read

Something many competitors fear more than anything is weigh ins. This fear is justified most of the time, as many competitors also have very little education on how to properly cut weight for jiu jitsu.

The majority of competitors will go through starvation, sauna sessions, running miles, and more just to lose a small amount of weight. This leaves them miserable before and after weigh ins.


Who wants to compete when every time you have to starve for a month? The answer is no one.


I was in this boat as well. Terrified of each weigh in because I was starving myself to make the weight. However, now I have a system to cutting weight before a tournament. And it allows me to shed the pounds without starving myself, and without feeling like garbage before and after stepping on the scale.


Let’s dive into it.


Note: If you are 1 week out or less, you can skip to step #3.


Step #1: Plan Ahead


Start Early

Begin cutting weight at least 4-6 weeks before the tournament. This timeline allows for gradual weight loss, reducing the risk of muscle loss and dehydration.


Set a Realistic Goal

Determine your target weight class and calculate how much weight you need to lose.


For example, if I register for 185, 4 weeks out I don’t want to be any heavier than 195. That allows for 3-6 lbs of weight loss from weeks 4, 3 and 2, and then around 5 lbs of weight loss for the final week which will consist of mostly water.


To find your calorie needs, I recommend Cronometer or ChatGPT, as it’s more reliable than a random BMI calculator online, but any BMI/calorie tracker app will work just fine. Aim for a sustainable weight loss of 1-2 pounds per week.


Step #2: Adjust your diet


Caloric Deficit

Create a moderate caloric deficit by reducing your daily calorie intake. Use a food diary or a tracking app to monitor your calories. I recommend a deficit between 500-1000 calories per day.


Macronutrient Balance

Focus on a balanced diet with a good ratio of protein, carbohydrates, and fats. Aim for:


Protein

1.2-1.6 grams per kilogram of body weight to preserve muscle mass.
Carbohydrates: 3-5 grams per kilogram of body weight for energy.
Fats: 0.5-1 gram per kilogram of body weight for hormonal balance and energy.


High-Quality Foods

Prioritize whole, nutrient-dense foods such as lean meats, fish, eggs, whole grains, fruits, and vegetables. Avoid processed foods and sugary snacks.


Pro tip

If you are having a hard time with the deficit, I recommend adding in potatoes, eggs and more protein to feel more full throughout the day.


Step #3: Hydration and Water manipulation


Hydrate Early

Maintain high hydration levels during the initial phase of cutting weight for jiu jitsu. Drink plenty of water (3-4 liters per day) to support your metabolism and overall health.


Water Loading

About 5-7 days before the tournament, begin water loading by increasing your water intake significantly (up to 8 liters per day) for 3-4 days. This helps to flush out your system and manipulate water retention.


Gradual Reduction

Reduce water intake progressively 3 days before the weigh-in. For example: 

  • 3 days out: 6 liters
  • 2 days out: 4 liters
  • 1 day out: 1 liter


Minimal Water on Weigh-in Day

On the day of the weigh-in, try your best not to consume any liquids until stepping off the scale after weighing in


Step #4: Salt and Carbohydrate Manipulation


Reduce Sodium

Lower your sodium intake 5-7 days before the weigh-in to decrease water retention. Avoid salty foods and processed products.


1-2 days out, I recommend keeping sodium intake below 1500mg, preferably below 1000mg.


Carbohydrate Tapering

Gradually reduce your carbohydrate intake 3-4 days before the weigh-in. Carbs hold water in the body, so reducing them helps with water weight loss. Replace high-carb foods with lean proteins and vegetables.


Exercise and Training Adjustments


Regular Training

Continue your regular jiu jitsu and strength training sessions to burn calories and maintain muscle mass. However, you want to increase your training intensity on the mats in the weeks leading up to your tournament.

Sweat Sessions

In the last week, incorporate light sweat sessions such as hot yoga, sauna, or wearing extra layers during training to help shed water weight. 

 

Sleep and Recovery


Prioritize Sleep

Aim for 7-9 hours of quality sleep per night to support recovery and stress management.


Active Recovery

Include stretching, foam rolling, and light activities on rest days to keep your body loose and ready for competition.


Step #5: Weigh-in Day


Final Preparations

On the day of the weigh-in, monitor your weight closely. If necessary, use short, controlled sweating sessions (e.g., sauna, hot bath) to shed the last few pounds.


Rehydration and Refueling

After weigh-in, rehydrate slowly with electrolyte-rich fluids and start refueling with easily digestible carbohydrates and lean proteins. Avoid overeating and focus on small, frequent meals.


Mental Preparation


Stay Positive

Keep a positive mindset throughout cutting weight. Stress can impact your weight loss and jiu jitsu performance, so practice relaxation techniques such as meditation and deep breathing.


Visualization

Visualize your success in the tournament and stay focused on your goals. Mental preparation is as important as physical readiness.


Summary

 

  • 3-4+ weeks out: Begin calorie deficit
  • 1 week out: Begin water loading and decreasing sodium intake
  • 1-2 days out: Minimal sodium intake, lessen water intake
  • Day of weigh-in: Minimal or preferably no food or water before weigh-in. Go get that gold!


Conclusion


Cutting weight for jiu jitsu is something that most fear and see as miserable. But this does not have to be the case. If you follow these steps, I guarantee you will have a much more comfortable weight cut than in previous competitions.

FAQ

Porrada is a Portuguese term commonly used in Brazilian Jiu-Jitsu (BJJ) and Brazilian culture to describe a tough, intense, and gritty style of training or fighting. The direct translation of porrada from Portuguese to English is "beating" or "brawl." It embodies the spirit of going all out, giving your maximum effort, and pushing through challenges. In BJJ, practicing porrada means training with high intensity and determination.

This website is a collection of resources curated by grapplers, for grapplers. Our goal is to provide you with all the information you need to succeed. Whether you want to learn about nutrition, training on the mats, lifting, or anything in between, we are here for you. We want to see you on the podium most of all, and we hope to help you do exactly that. If you have any questions, feel free to shoot us an email or DM us on any of our social profiles!

There are two main ways you can get started with training: 1) You can find a BJJ gym near you and do a trial day, or 2) you can create your own mini home gym and start training with friends. Option #2 is how our team at Porrada got started! We ordered 1-inch thick puzzle mats in a 10’x10’ square and began training using online resources. If you do start with the second option, we recommend eventually finding a gym down the road in your career. It will help you by allowing you to roll with more people and receive high-level instruction.

BJJ is quite similar to wrestling. Both start standing and use takedowns as a method to score points. Both use very similar mechanics overall. The main differences are that there are no pins (you can be on your back in Jiu-Jitsu), BJJ involves submissions, and the points system for each is very different. BJJ grants points for takedowns/sweeps, back control, mount, guard passes, and knee on belly. Wrestling grants points for takedowns, escapes, and back points (back exposure for freestyle).

BJJ is a very unique sport in many ways. There are so many incredible benefits to training Jiu-Jitsu. The biggest reasons we advocate for it are the mindset training and the added ability to defend yourself. In BJJ, you are forced to humble yourself over and over again, every single day. This sport is a great way to mature rapidly and generally become a better person (in our opinion). You will also have a better ability to defend yourself than 99% of the population—a pretty big bonus.

You’re never too old to start training! We see people on the mats of all ages and sizes. Large and small, old and young can, and should, train BJJ. If you are on the older side, it is perfectly acceptable to take it slow and learn at your own pace. You don’t always have to go full speed—don’t worry. There are typically also classes that separate people by goals. Certain classes are for those who want to compete, some are for general instruction, and some are specifically for self-defense teachings. There is a place for everyone on the mats.
