The Productivity Pyramid: How to Fuel Your Brain for Better Focus, Energy and Performance at Work
"Your brain is your biggest work asset. So why do we spend so much time upgrading our laptops, coffee machines and office chairs, but so little time thinking about what fuels the organ that does all the work?"
It's 3pm.
Your concentration has disappeared.
You're reading the same email for the third time.
You convince yourself another coffee will solve the problem.
The biscuit tin suddenly becomes incredibly tempting.
Sound familiar?
Most of us blame these afternoon slumps on being busy, stressed or simply "not a morning person." But in reality, your brain may simply be responding to how you've fuelled it throughout the day.
As a sports dietitian, I spend my days helping athletes optimise performance through nutrition. The interesting thing is, the exact same principles apply whether you're preparing for an AFL grand final, presenting to a boardroom, studying for exams or juggling work and family life.
Your brain is a high-performance organ. It needs the right fuel, hydration, movement and recovery to perform at its best.
The good news? Improving your productivity doesn't require expensive supplements or complicated biohacks.
It starts with getting the foundations right.
Why brain health matters more than you think
When people hear the words brain health, they often think about preventing dementia later in life.
While that's certainly important, brain health is something that affects every single day of your life.
Your brain controls:
concentration
memory
decision making
learning
creativity
emotional regulation
problem solving
reaction time
communication
productivity
In other words, almost everything you do at work relies on your brain functioning well.
If you've ever forgotten someone's name halfway through a conversation, struggled to concentrate after lunch or felt unusually irritable at the end of a long day, you've experienced how brain health influences daily performance.
The exciting part is that many of these things are modifiable through lifestyle.
Nutrition is one of the biggest pieces of that puzzle.
Your brain is incredibly expensive to run
Although your brain weighs only around 2% of your body weight, it uses approximately 20% of your resting energy requirements every single day.
That's an enormous amount of energy for such a relatively small organ.
Unlike your muscles, your brain can't simply "switch off" when you're sitting quietly. It's constantly processing information, regulating body systems, making decisions, storing memories and controlling every thought and movement.
Its preferred fuel?
Glucose.
Your brain uses approximately 100-130 grams of glucose every day, which comes primarily from the carbohydrates you eat.
Imagine trying to drive across Tasmania with your fuel gauge sitting on empty.
You wouldn't expect your car to perform well.
Yet many of us expect our brains to power through meetings, deadlines and difficult decisions after skipping breakfast or surviving on coffee alone.
What is the best food for brain health?
One of the most common questions people ask is:
"What's the best food for brain health?"
The truth is, there isn't one magical "brain food."
So rather than searching for one "superfood," focus on eating a variety of foods!
Your brain doesn't need perfection.
It needs consistency.
Carbohydrates: Your brain's preferred fuel
Unfortunately, carbohydrates have developed an unfair reputation over the past decade.
Yet carbohydrates remain your brain's favourite fuel source.
Every carbohydrate you eat—whether it's bread, rice, pasta, fruit, milk or breakfast cereal—is broken down into glucose.
That glucose then provides energy for your brain to think, process information and concentrate.
When you don't eat enough carbohydrate, you may notice:
difficulty concentrating
slower thinking
fatigue
irritability
stronger cravings later in the day
These aren't signs that your brain is "broken."
They're often signs that it's under-fuelled.
Does focusing on low GI carbs help improve concentration?
Not all carbohydrates affect your body in exactly the same way.
Some digest quickly, causing blood glucose to rise and fall rapidly.
Others digest more slowly.
This is where the glycaemic index (GI) becomes useful.
Low GI foods generally release glucose into the bloodstream more gradually, helping provide steadier energy over several hours.
Examples include:
rolled oats
grainy bread
wholegrain wraps
legumes
milk
yoghurt
most fruit
basmati rice
sweet potato
Choosing mostly low GI carbohydrate foods throughout the day may help reduce energy crashes and support more consistent concentration—particularly during long meetings or busy workdays.
That doesn't mean every meal needs to be perfectly low GI.
It simply means making these foods your regular foundation.
Why skipping breakfast affects productivity
One of my favourite questions to ask clients is:
"Would you drive to Launceston with the fuel light on?"
Almost everyone laughs.
Of course they wouldn't.
Yet every day, thousands of Australians expect their brains to function all morning after skipping breakfast.
Or they grab nothing more than a coffee on the run.
Breakfast isn't important because someone once said "it's the most important meal of the day."
It's important because your brain has likely gone 10-12 hours without food.
Providing it with carbohydrate, protein and fibre early in the day gives your brain the fuel it needs to begin working efficiently.
Simple balanced breakfasts include:
overnight oats with yoghurt and berries
eggs on wholegrain toast
Greek yoghurt with fruit and muesli
wholegrain toast with peanut butter and banana
smoothies made with milk, oats and fruit
Remember, breakfast doesn't need to be Instagram-worthy.
It simply needs to happen.
The role of protein and fibre for sustained energy
Many people think protein is only important if you're trying to build muscle.
In reality, protein plays an important role in workplace performance too.
Including protein at meals helps improve fullness and satisfaction, making it less likely you'll spend the afternoon searching the office kitchen for snacks.
Fibre works alongside protein to slow digestion, support gut health and provide a steadier release of energy throughout the day.
The simplest way to remember this?
At most meals, try to include:
a quality carbohydrate
a source of protein
plenty of colourful vegetables or fruit
That's a balanced meal.
Not because of calories.
Because of performance.
Hydration and brain performance
Even mild dehydration can affect:
attention
memory
reaction time
decision making
In many cases, those afternoon headaches or feelings of brain fog aren't solved by another coffee.
They're solved by drinking enough water.
A simple habit is keeping a water bottle on your desk and drinking regularly throughout the day rather than trying to "catch up" later.
Coffee isn't giving you energy
This is probably one of the biggest myths around workplace productivity.
Coffee doesn't actually create energy.
Instead, caffeine blocks adenosine—the chemical that makes you feel tired.
That's why coffee makes you feel more alert, even though your body hasn't magically produced more energy.
Coffee absolutely has its place.
But if you're relying on multiple coffees every afternoon, it may be worth asking:
Am I actually tired...
Or am I under-fuelled, dehydrated or sleep deprived?
Movement is brain food too
Nutrition isn't the only thing your brain needs.
Exercise and movement improve:
blood flow
oxygen delivery
attention
executive function
mood
production of Brain-Derived Neurotrophic Factor (BDNF), sometimes referred to as "fertiliser for the brain."
The best part?
You don't need a gym membership.
Small "brain breaks" count.
Stand up every hour.
Walk while taking phone calls.
Use the stairs.
Stretch between meetings.
Every bit of movement helps.

The Productivity Pyramid: The framework I want every office worker to know
Here's where I think people often get productivity backwards.
We spend hundreds of pounds—or in Australia, hundreds of dollars—on supplements, fancy coffees and productivity apps while ignoring the basics.
That's why I use what I call The Productivity Pyramid.
Think of it exactly like building a house.
You can't build the roof before you've laid the foundation.
Level 1: Sleep (Your foundation)
If your sleep is poor, everything above it becomes harder.
Aim for around 7-8 hours of quality sleep where possible.
Simple habits include:
waking at a consistent time
getting outside in morning sunlight
reducing caffeine later in the day
limiting alcohol before bed
reducing screen time before sleep.
Level 2: Nutrition
Before worrying about supplements (like Creatine), ask yourself:
Did I eat breakfast?
Have I gone five or six hours without eating?
Did I include protein?
Have I had enough carbohydrate?
Have I drunk enough water?
Most people will see significant improvements simply by eating consistently throughout the day.
Level 3: Movement
Movement keeps blood flowing to your brain.
Aim to meet the Australian Physical Activity Guidelines where possible, but also remember that short movement breaks during the workday matter too.
Five minutes every hour is far better than sitting still for eight.
The tip of the pyramid: Caffeine, creatine and supplements
Supplements are exactly that—supplements.
They can complement good habits.
They cannot replace them.
Emerging research suggests creatine may support cognition during periods of sleep deprivation or high mental demand, but the evidence is still evolving.
If the base of your pyramid isn't strong, no supplement will compensate.
Small changes create big improvements
One of the biggest mistakes people make is trying to overhaul everything overnight.
Instead, choose one habit from each layer of the pyramid.
Maybe that's:
✔ Eating breakfast three days this week.
✔ Taking a five-minute walk every lunchtime.
✔ Filling your drink bottle twice each day.
✔ Going to bed 30 minutes earlier.
Small improvements repeated consistently are what create lasting change.
The question that changes everything
Instead of asking:
"What should I eat?"
Try asking:
"What does my brain need from me today?"
That single question shifts the focus away from diets, restriction and guilt.
Instead, it puts the emphasis where it belongs—giving your brain the fuel, movement and recovery it needs to help you think clearly, perform well and feel your best.
Because whether you're managing a business, studying for exams, raising children, training for your next sporting event or simply trying to get through a busy workday...
Your brain deserves to be treated like the high-performance athlete it is.
