Evidence-based articles on nutrition for combat athletes, tactical operators, and high performers.
The first hard outdoor session of a summer fight camp is the one that breaks the fighter who didn't acclimate. Body temperature climbs past the threshold for heat-stroke risk, the cut at the end of camp is going to be harder than it needed to be, and the early-camp performance loss is permanent. Here is the 14-day heat-acclimation protocol I program at the start of every summer camp — the daily heat exposure schedule, the sodium and fluid loading targets, the supplements that help and the ones that don't, and how the acclimation changes the late-camp cut math.
Most fighters take 300 mg of caffeine on fight night and feel about the same as they did taking 200 mg on a Tuesday in camp. That is tolerance — and it is the silent ergogenic tax most camps never address. Here is the 10-day pre-fight taper that resensitizes the adenosine receptors, the dose math during the taper window, and why the protocol is timed to land on fight week, not start it.
Caffeine on fight day is timing, not just dose. The 5-6 hour half-life means a pre-walkout dose that's perfect for the cage is still circulating at 2 AM when the body needs to crash. Here is the fight-day caffeine protocol — when to dose, when to pivot to citrulline, and how to recover the sleep architecture after the fight.
Most fighters eat the same way on Monday — a heavy drilling day at 50% intensity — as they do on Wednesday — a hard sparring round followed by conditioning at 90% intensity. The result is hard days under-fueled and easy days over-fueled. Here is the session-by-session carb target that fixes both.
Most fighters lose more progress in the two weeks after a fight than in the two weeks before. The bounce is not metabolism — it is a structureless eating window that follows a structured deprivation. Here is the day-by-day rebound protocol that brings glycogen, sleep, and body weight back to baseline without overshooting.
Fight week is not a single nutrition plan — it is six different plans across seven days. Here is the day-by-day calorie and macro cycling protocol I run from Monday's last hard session through Saturday's walkout, with the numbers that change and the reasons each shift exists.
Most camps wait for symptoms before pulling blood. The smarter pattern is mid-camp bloodwork — ferritin, vitamin D, CK, hormones, kidneys — read against the cut, the brain-health baseline, and the training load. Here is the panel I run, when I run it, and what each number tells you about whether the fighter is camp-ready.
The opponent missed weight. The promoter offered a catch-weight. The fight is in nine days. Here is how a camp re-runs the cut math without panicking — and the four mistakes that show up when the number moves late.
The hour between hand wraps and walkout is where most fight-day fueling plans fall apart. Here is the protocol — caffeine timing, last-carb dose, sodium top-off, fluid rate — and the four mistakes that kill it.
You made weight. The cage opens 24 hours later. Most fighters spend that window making the same five mistakes — and the camp around them lets it happen. Here is what actually loses fights between the scale and the first round.
A cornerman runs the day-of nutrition execution. Here is the cooler list, the round-by-round pour rate, the post-fight refuel window, and the common cornerman mistakes that cost fights.
The 90 days after a concussion are a metabolic recovery window most fighters mismanage. Here is a phase-by-phase nutrition protocol — DHA, creatine, choline, magnesium — for combat athletes returning from a head injury.
A wrestling tournament can put a competitor on the mat seven times in one day. A BJJ bracket can stack four matches in division and four more in absolute. Here is the between-bouts fueling protocol that holds up across the whole day.
Combat athletes take more cumulative head impact than almost anyone in sport. Here is the nutrition baseline that belongs in every camp — not just after a concussion, but every day.
Training camps pull fighters away from home for weeks at a time. Here is a working playbook for holding your nutrition together when the environment is working against you.
