Refining the weight cut is everything.

The smaller the percentage of bodyweight you pull in fight week, the better the outcome. Not just on the scales, but in the cage.

When the body isn’t dragged into the weigh-in compromised, it’s in a far healthier and more optimised position to refuel and rehydrate properly. Glycogen loads better. Fluids restore faster. Electrolytes balance easier. Performance comes back online instead of just survival mode.

Less stress. Better recovery. Sharper output.

That’s the difference between making weight… and making a statement.

Working with as both a client and a friend for years now has been one of the greatest evolutions of my coaching career.

What started as “make weight and perform” has turned into a constant refinement of process. Every camp we’ve tightened things up. Better data. Better communication. Better adjustments. Smarter refeeds. Cleaner cuts. Less guesswork. More precision.

We’ve learned his body across stress blocks, injuries, travel, fight weeks etc. We’ve seen how his weight responds to sodium, sleep, inflammation, volume, mindset. We’ve refined how aggressively we push and when we pull back. When to fuel harder. When to protect recovery.

Nutrition at this level isn’t just calories and macros. It’s timing. It’s psychology. It’s nervous system management. It’s making sure he performs on the night

Cutting. Rebuilding. Pushing output. Repeating.

I have lived it personally.

I have worked with athletes operating at a high level across multiple disciplines.

The deeper I move into this space, the clearer something becomes.

Much of the current nutrition conversation, not just in combat sport but across performance and physique culture, is still surface level.

Hit your calories.
Get enough protein.
Stay flexible.
Trust the deficit.

For many people, that is enough to see change.

It is not enough to build or sustain elite performance.
There is a difference between dieting and preparing.
There is a difference between weight loss and adaptation.

There is a difference between looking lean and performing under load.

Nutrition at a higher level is not simply arithmetic.
It is physiology.
It is timing.
It is context.
It is feedback.

Energy availability determines hormonal output.

Carbohydrate availability influences training quality and recovery.

Micronutrient sufficiency underpins mitochondrial function.

Fat intake modulates endocrine resilience.

Sodium, hydration and glycogen alter how you feel, move and think.

The margin for error narrows as demands increase.

What works for someone training three times a week may not work for someone training twice a day.
What works for aesthetic goals may not support long term health.

What works short term may quietly accumulate cost long term.

The body keeps score.

This is not about extremism.
It is not about rigidity.
It is not about demonising food or chasing perfection.
It is about depth.
It is about precision.
It is about systems thinking.
It is about individualisation.
It is about recognising that food is not just fuel, but information that shapes internal environment.

The more I train and the more people I work with, from everyday high performers to elite athletes, the stronger my conviction becomes.

Most people do not need more noise.

They need more depth.
More context.
More understanding.
Not louder advice.
Smarter application.
Living it. Studying it. Applying it. Sharing it.

One week post UFC Sydney and amazing result!

High level athletes require high level and detailed coaching.

It involves real time decision making.

Throughout this entire camp I’ve worked with Joni in depth, check ins, daily messages, constant adjustments, and constant feedback loops.

Because at the top level, nutrition is never “set and forget”.

Macros change.
Training load changes.
Sleep changes.
Stress changes.
Hydration changes.
Weight fluctuates.
Appetite shifts.
Recovery changes.
Performance changes.

And every one of those variables affects what the athlete needs next.

Some days the scale is down, but performance is flat.
Some days weight is up, but the athlete feels sharper than ever.
Some days everything looks perfect on paper, but mood, energy, and recovery tell a completely different story.

That’s why we don’t just coach calories.

We coach the entire system.

We use the scale, but we also use training output, sparring quality, energy levels, digestion, sleep, mood, and how the body is responding session to session.

Then we adjust.
Sometimes that means pulling carbs.
Sometimes it means pushing carbs.
Sometimes it means increasing sodium.
Sometimes it means backing off fibre.
Sometimes it means changing meal timing.
Sometimes it means doing nothing and letting the body settle.

This is what real fight nutrition looks like.

Individualised.
Data driven.
And built around performance first, not just chasing a number on the scale.

Because anyone can give an athlete macros.

But it takes experience to adjust them daily, keep them fuelling hard sessions, keep weight moving in the right direction, and keep the athlete calm, confident, and in control right through camp.

Nutrition is never a straight line. Progress doesn’t happen in perfect weekly blocks, and the people who get the best results aren’t the ones who “try harder”… they’re the ones who learn how to reflect, assess, and adjust properly.

Because real nutrition isn’t just hitting numbers for a few days and hoping the scale moves.

It’s understanding what your body is actually doing week to week, and being able to change the right variable at the right time.

Some weeks your intake needs to shift.
Some weeks your training load is the issue.
Some weeks your sleep is quietly destroying your recovery and appetite.
Some weeks stress, hydration, sodium, digestion, and routine are the real reason progress stalls.

This is why the foundation of long term results is feedback.

Being able to:
• track patterns, not just outcomes
• assess trends, not daily fluctuations
• adjust food based on performance and recovery
• understand when to push and when to pull back
• change multiple pieces at once when needed
• stay consistent without being rigid

Because no plan works forever unchanged.

Your body adapts. Your schedule changes. Your training intensity goes up. Life happens. Your appetite shifts. Your sleep gets disrupted. Your weight fluctuates. Your energy changes.

And the people who succeed are the ones who don’t panic when that happens. They respond with strategy.

That’s the real path to results. Not perfection. Not extremes. Not random changes.

Reflection. Assessment. Adjustment.

Every week. Every phase. Until it becomes second nature.

Fight Camp Nutrition

DM “fight camp” if ready to get your nutrition right for your year

22/01/2026

If you want more than generic advice, this is where it starts.

Bloodwork takes nutrition from surface-level to precise, built on real insight into how your body is functioning.

No more guessing whether to eat more, less, or differently.

No following random advise.

Just clear, evidence-based decisions that align your nutrition, training, and results.

This is working with your physiology.

I have spent the last few years experimenting my approach to prescribing nutrition, supplements and training … and what I have found, is that what is best is … a way of eating I can repeat day in day out for many weeks, even months.

This is both from a functional and enjoyability standpoint. Blending the two allows for sustainability over longer period of time, which in essence is the foundation consistency, and in my opinion the real way to achieve the physique and performance changes most are seeking.

People struggle with eating too little, mistiming meals, extremely restrictive and using plans that don’t match their lifestyle.

When calories stay too low for too long:
• You move less without realising
• Training feels harder
• Recovery slows
• Strength drops
• Muscle loss becomes more likely

Then people say:
“I’m barely eating and nothing is changing.”

That’s not a willpower problem.
It’s a structure problem.

The way most should start is:
• Protein spread across meals to support muscle
• Carbs placed around training to fuel sessions
• Fats included to keep meals satisfying
• Fibre balanced so digestion stays comfortable
• Calories set for progress, not burnout

But here’s what most plans miss:

It includes foods you actually enjoy.
Not as a “treat”. Not as a reward.
Just as part of normal eating.

Because when food feels overly strict:
• Hunger creeps up
• Cravings get louder
• Choices get harder at night
• “One off” days happen more often

So yes, there’s structure.
But there’s also chocolate.
Meals out.
Foods that feel normal.

The goal isn’t being “on” or “off” a plan.
The goal is eating in a way you can keep up all year round.

No extreme cuts.
No rebound weeks.
No starting over every Monday.

Just smart fuelling that:
• Supports training
• Improves body composition
• Feels realistic
• Fits real life
• Still delivers results

That’s the difference between short-term weight loss
and long-term physique change.
