HEALTH AND SAFETY
This article is general education. It is not an individual diet, dehydration plan, or medical plan. Fighters who need to make weight should use a plan that fits their body, sport, weigh-in rules, health, and time before competition.
TL;DR / Direct answer
A fight camp is the set period before a bout when a fighter prepares for one competition. Training gets more specific, body weight may move towards the weight class, and food and recovery should match the work being done. Condition Nutrition’s view is simple: a fight camp is a performance phase with a weight target inside it, not a weight-loss phase with training attached. [1]
Meaning note: This guide uses “fight camp” as two words to mean the preparation period before a bout. It is not about the FightCamp home fitness brand.
Key takeaways
- A fight camp is built around a known fight date and the needs of that bout.
- Training, food, recovery, and body-weight work should support each other.
- Fight camp and fight week are not the same job.
- Cutting food too hard can work against the sessions that are meant to make you better.
- The plan should change with training load, body weight, and time left before the weigh-in.
- A fighter should arrive at fight week with fewer problems to solve, not more.

What is a fight camp?
A fight camp is the formal period before a set fight date when training becomes focused on that event. The 2025 ISSN position stand describes fight camp as a distinct phase between general preparation and fight week. It says the phase often lasts about eight to ten weeks, although real camps can be shorter or longer. [1]
A fighter may work on skills, tactics, sparring, strength, conditioning, recovery, and body weight during the same block. That is why a camp should not be treated as one long diet. The food plan has to help the fighter do the work as well as reach the right weight. [1]
How long does a fight camp last?
There is no single length that fits every fighter. The ISSN paper describes fight camps as commonly lasting about eight to ten weeks, while combat-sport practice can vary because fights are sometimes booked on shorter notice. [1]
The useful question is not only “How many weeks do I have?” It is also “What has to change before the fight?” A fighter who is already fit and close to the class has a different job from a fighter who is far above the limit or coming back after time away.
What should a fight camp actually do?
A good fight camp should make the fighter better for the bout while making the final week easier to manage. Condition Nutrition uses three jobs to judge whether the plan is working.
| Job | What it means | Bad sign |
| Build performance | Support the skills, sparring, strength and conditioning needed for the bout. | The fighter is getting lighter but key sessions keep getting worse. |
| Move body weight | Bring body mass towards the class at a planned pace when weight loss is needed. | Large changes are left until the final days. |
| Shrink fight week | Reduce the amount of last-minute work and guesswork before the weigh-in. | Fight week becomes the main weight-loss plan. |
Condition Nutrition view: a fight camp is a performance phase with a weight target inside it. It is not a weight-loss phase with training attached. This is an editorial position based on the need to support training while body weight is managed. [1][2]
How should food change during fight camp?
Food should follow the work. Hard days and days with more than one session usually need more fuel than rest days or light skill days. The ISSN position stand says carbohydrate should support training demands, while protein should be kept high enough to help protect lean tissue during a planned drop in body weight. [1]
The 2025 ISSN position stand gives useful guardrails for planned weight descent during fight camp. Its practical guidance says carbohydrate should not drop below 3 to 4 g/kg/day, protein during weight descent should be around 1.6 to 2.2 g/kg/day, and a planned body-mass loss of about 0.5 to 1 kg per week can be used as a practical target. These are not copy-and-paste targets for every fighter. [1]
Fight camp nutrition guardrails
| During fight camp | Useful evidence-based guardrail |
| Carbohydrate | Do not routinely drop below 3 to 4 g/kg/day during planned weight descent. [1] |
| Protein | Around 1.6 to 2.2 g/kg/day during planned weight descent. [1] |
| Body-mass change | About 0.5 to 1 kg per week is given as a practical target in the ISSN position stand. [1] |
| Main job | Keep training quality and recovery supported while body weight moves towards the class. |
Condition Nutrition view: these numbers are guardrails, not a meal plan. If the diet gets a fighter lighter but repeatedly makes pads, sparring, strength work, or recovery worse, the plan is working against the reason the fighter is in camp. [1]
| What this evidence does NOT mean The ISSN guardrails do not mean every fighter should eat the same amount, lose the same amount of weight, or use the same cut. Sport, camp length, body mass, body composition, training load, and time between weigh-in and competition can all change the plan. [1] |
A 2024 systematic review of weight-loss practices in combat sports found that gradual dieting and extra exercise were among the most common methods used. It also found that scientific practitioners had little influence on many athletes’ weight-loss choices. That matters because common practice is not the same as a good individual plan. [2]
What is the difference between fight camp and fight week?
Fight camp is the longer build towards the fight. Fight week is the final short phase around the weigh-in and competition. Mixing the two jobs together is one reason fighters can end up trying to solve too much at the end. [1]
| Area | Fight camp | Fight week |
| Main aim | Build towards the bout while managing body weight over time. | Finish the weigh-in plan and prepare to compete. |
| Training | Higher training load, skill work, sparring and conditioning. | Training is reduced and made more specific to the event. |
| Food | Fuel the work while creating a planned weight trend if needed. | Food, fibre, carbohydrate and fluid may change for a short-term reason. |
| Main risk | Under-fuelling the work for too many weeks. | Trying to fix a large body-weight gap too late. |
What goes wrong in a bad fight camp?
The most common problem is not that the fighter does too little. It is that too many jobs fight each other. The fighter trains harder, eats less, tries to lose weight fast, sleeps poorly, and still expects every session to improve.
The ISSN position stand warns that losing weight too quickly while energy needs are not being met can harm skill training, endurance, recovery, motivation, and lean tissue. [1] A 2023 review of rapid weight loss also found mixed performance results and reported negative effects in many of the studies it assessed, especially as rapid losses became larger. [3]
That does not mean all weight loss is bad. It means the weight plan should be judged by what it does to the whole camp, not only by what the scale says.
Who needs an individual plan?
Individual help matters most when the margin for error is small. A fighter should get qualified help when there is a meaningful weight cut, a history of difficult cuts, a same-day or short recovery window, repeated low energy, illness, injury, or a plan that depends on heavy dehydration.
- The fighter is not sure which weight class is realistic.
- The body-weight trend is not moving as planned.
- Hard sessions keep getting worse as food is cut.
- The weigh-in rules or recovery time are different from the fighter’s last event.
- The plan needs dehydration, heat, or other acute weight-loss methods.
The Condition Nutrition approach to fight camp
The plan comes before the product. First set the fight date, current body weight, target class, training week, weigh-in rules, travel, and recovery time. Then make the food plan fit that real week. Body weight can be adjusted as the camp moves, but the aim is to protect the training that wins the fight.
Condition Nutrition’s Fight Camp Support includes weekly tailored nutrition, body-weight monitoring, hydration guidance, fight-week planning, post-weigh-in refuelling, and check-ins. The current service page lists an Elite plan at £250 per month and a VIP Pro plan at £500 per month. Prices should be checked again on the live page before this article is published.
If you have a fight booked and want the food and weight plan built around the whole camp, see Fight Camp Nutrition Plans.

Frequently asked questions
What is a fight camp?
A fight camp is the set period before a planned bout when training becomes focused on that event. Fighters may work on skills, tactics, sparring, strength, conditioning, recovery, and body weight during the same block. [1]
How long is a fight camp?
There is no fixed length for every fighter. The 2025 ISSN position stand describes fight camps as commonly lasting about eight to ten weeks, but real camps can be shorter or longer depending on the fight notice and the athlete. [1]
Is fight camp the same as fight week?
No. Fight camp is the longer preparation block. Fight week is the final phase around the weigh-in and competition, when training falls and short-term food or fluid changes may be used for a specific reason. [1]
Should you lose weight during fight camp?
A fighter who needs to move towards a lower weight class may lose body mass during camp, but the plan should still support training and recovery. The rate and amount should be individual rather than copied from another fighter. [1][2]
What should you eat in fight camp?
Food should match the training being done. Hard days normally need more fuel, while protein and carbohydrate should be planned to support recovery, training quality, and any gradual body-weight change that is needed. [1]
When should a fighter get help with fight camp nutrition?
A fighter should get qualified help when the cut is large, past cuts have gone badly, recovery time after the weigh-in is short, or the plan involves dehydration or heat. Individual support is also useful when training quality drops while body weight is being reduced. [1][3]
