Nutrition that actually helps a combat athlete train
Most fight-nutrition content is written by people who have never missed weight or sat on a stool between rounds. I have. The stuff that works is boring: enough food, enough salt, enough sleep, and a plan for the night before you have to make a number.
I am not a dietitian. I am a fighter who got tired of watching teammates under-eat all week, then panic-load junk 48 hours out.
Key takeaways
- Camp food is fuel, not a personality.
- Protein at every meal, carbs around hard sessions, water and sodium on purpose.
- Creatine and caffeine have more evidence than almost anything sold as a "fighter stack."
- If you compete under drug testing, skip gray-market recoveries and stick to food plus NSF-certified basics.
Eat enough before you optimize
If you are cutting 15 pounds in a sauna because you under-ate for six weeks, no powder is going to save your last round. I keep meals simple in camp: rice or potatoes, chicken or beef or eggs, fruit, a vegetable I will actually finish, and something salty. That is it.
Hard days get more carbs. Easy days get slightly less. I do not count macros to the gram unless I am inside two weeks of a fight. The scale and how I feel in sparring tell me more than an app.
Protein, without the cult
A palm-sized portion of meat or a scoop of whey at each meal is enough for most people in camp. I use whey when I cannot cook. I do not chase 300 grams. I also do not do long fasts in fight camp. You cannot pad when you are empty.
Carbs are not the enemy of making weight
Sparring, bag work, and jump rope run on glycogen. If you strip carbs all camp you will feel flat, then you will blame your gloves. I put most of my carbs around training: fruit or rice before, rice or potatoes after. The cut comes later, under a coach, not from a TikTok grocery ban.
Salt and water
Fighters dump sodium then wonder why they cramp. I drink water through the day and add electrolytes when I am sweating through two sessions. Pick a mix with sodium you can taste. Fancy claims do not matter if you will not drink it.
The two supplements I bother with during camp
Creatine monohydrate, five grams a day, every day, including fight week unless my cut coach says otherwise. A simple option is Nutricost Creapure creatine. Caffeine, timed, not all afternoon. Everything else is optional. I wrote a separate post on supplements I will actually spend money on.
Buy on Amazon
- Creatine: Nutricost Creapure 500g
- Whey: Optimum Nutrition Gold Standard whey
What I skip
Detox teas. "Shred" fat burners. Anything that promises to melt weight overnight. Anything sold as a research peptide on Instagram. If it needs a secret checkout link, it does not belong in a camp that has to pass a commission physical.
For the legal and testing mess around peptides, read what the FDA and USADA are actually doing.
Train in kit that survives camp
If you are already in camp, skip the fashion drop and grab the Fight Camp Kit or dry-fit rash guards. Free USA shipping over $100. 30-day returns.
Questions I get
Do I need a meal plan from an influencer?
No. You need consistent meals and a cut plan from someone who has taken a fighter to the scale.
Can I train fasted?
Some people do easy work fasted. I do not spar fasted. Your call, but do not make it a religion.
What about fight-week food?
That is individual. I do not publish a cut protocol. Ask your coach.
