FIFO nutrition: how to eat well on a 2:1 roster — and why it changes how you perform
Published by Deborah Van Lith · XLR8 Your Health · Clinical Nutrition & Bowen Therapy, Perth and Mandurah
Ask a FIFO worker what they want from food and you'll rarely hear "abs". You'll hear something much more practical. I want to stop hitting a wall at 2pm. I want to stop waking up at 3am. I want to get through the fourth night shift without feeling like I'm wading through concrete. I want to stop putting on four kilos every swing.
That's not a vanity conversation. It's a performance and safety conversation, and it's the one we have most often with the FIFO clients who come to our Perth and Mandurah clinics.
Here's the thing nobody tells you when you first get on a plane to site: the food you eat is one of the few variables in FIFO life you actually control. You don't control the roster. You don't control the heat. You don't control the flight delays or the camp you get put in. But you do control what goes on the tray, what goes in your bag, and when you eat it. And those three decisions have a bigger effect on how you feel by day eight than almost anything else.
This is the practical version — built for real rosters, real camp buffets and real 40-degree days in the Pilbara.
First, the scale of the thing
Australia's mining workforce sits at around 314,500 people, with the bulk of it in Western Australia and Queensland. FIFO is not a niche arrangement — it's how a huge part of the state works. The 2021 Census put the Pilbara's population at around 82,000, a number that badly undercounts the people actually there because FIFO workers are counted where they sleep most of the year.
And the health data on this group is not flattering. Australian research on FIFO and rotation workers consistently finds higher rates of overweight and obesity, poorer diet quality, higher alcohol intake, disturbed sleep and elevated psychological distress compared with the general population. A 2022 cross-sectional study of Australian mining FIFO workers found exactly that pattern: too little fruit and vegetables, too much discretionary food, too much alcohol, too little sleep.
None of that is a character flaw. It's a system producing a predictable outcome. The question is how to work the system instead of being worked by it.
What the roster actually does to your body
Before we get to food, you need to understand the machine you're feeding. Three things happen on a swing, and they all interact.
Your body clock gets scrambled. Shift work involving circadian disruption was classified by the International Agency for Research on Cancer as a probable human carcinogen back in 2019 — a statement about chronic disruption, not about any single night shift. What matters practically is that your body runs on a 24-hour rhythm governing digestion, insulin sensitivity, body temperature, alertness and appetite. Night shift puts you in direct opposition to it. Your gut motility slows at night. Your insulin sensitivity drops. Your appetite for carbohydrate goes up. You are, in a very literal sense, eating at the wrong time.
You accumulate sleep debt. Research on FIFO shift workers consistently finds shortened sleep, fragmented sleep and impaired alertness, and the safety implications of that are obvious when your job involves heavy machinery or long drives. Sleep debt doesn't just make you tired — it raises ghrelin (the hunger hormone), lowers leptin (the fullness hormone), and makes high-sugar, high-fat food markedly more appealing. If you've ever demolished a plate of chips at 11pm on night shift and felt baffled by yourself afterwards, that's the mechanism.
Your appetite regulation shifts. Shift workers eat more of their energy later in the day, snack more, and eat more discretionary food. That's partly hormonal, partly environmental — the camp is open, the food is free, and there's not much else to do at 2am.
So the food problem in FIFO is not a willpower problem. It's a timing, access and hormonal problem. Which means the solution has to be structural, not moral.
The camp buffet problem
Let's be honest about camp food. It has improved enormously over the last decade, and most sites now offer genuinely good options — a salad bar, grilled protein, vegetables, fruit. The problem isn't the absence of good food. It's the architecture of the room.
A buffet at the end of a 12-hour shift, when you're exhausted, hungry and it's all free, is one of the most reliable overeating environments ever designed. Research on buffet behaviour is remarkably consistent: bigger plates mean bigger portions, more variety means more food consumed, and serving yourself means you eat more than if someone plated it for you.
Seven rules that work in a camp dining room
Walk the whole room before you pick up a plate. Thirty seconds. See what's actually good. Otherwise you fill up on the first thing you see and then go back for the thing you actually wanted.
Use the smaller plate if there are two sizes. This is the single highest-yield change in any buffet, and it costs nothing.
Protein and vegetables fill the plate first. Two-thirds of the plate. Then, if you still want it, the starch. Not the other way around.
Take one plate. Sit down. Wait ten minutes before deciding on seconds. You will almost never want them. The urge to go back is fastest in the first five minutes and it fades.
Dessert is a decision, not a default. Decide before you walk in whether tonight is a dessert night — not every night, not never. A rule you set in advance beats a decision you make while standing in front of a chocolate fountain.
Don't eat in your room. The room is for sleeping. Eating there is how a bag of shapes becomes a nightly ritual you didn't consciously choose.
Fill your water bottle before you go to the dining hall, not after. Hydration first, then food.
What performance actually needs
If your goal is to get through a swing feeling sharp rather than wrung out, there are five levers. In order of how much they matter.
1. Eat protein at every meal, including breakfast
Most FIFO workers get plenty of protein at dinner and almost none at breakfast. Breakfast is usually cereal, toast or nothing, and that's exactly backwards for a job with physical demands and 12-hour shifts.
Protein does three things for you. It preserves muscle while you're in a sleep-deprived, high-output, sometimes under-fuelled state. It stabilises blood sugar, which stops the mid-morning crash and the 2pm wall. And it's the most satiating macronutrient, which makes the buffet easier to handle.
Aim for 25 to 40 grams of protein per meal. That's roughly two eggs plus a yoghurt, or a decent serve of bacon and eggs, or a bowl of Greek yoghurt with nuts and seeds (skip the cereal-based muesli), or last night's leftover steak with your eggs if the camp allows it.
If you're doing physically demanding work, the general range that works well is 1.2 to 1.6 grams of protein per kilogram of body weight per day. For an 85 kg worker that's 102 to 136 grams daily. It sounds like a lot and it isn't — it's a protein source at each of three meals plus a snack.
2. Time your biggest meal earlier than you want to
This is the counterintuitive one, and it's the one the research supports most strongly.
Studies from the University of South Australia's sleep and chronobiology group have looked at what happens when you eat a full meal versus a snack versus nothing during a simulated night shift. Eating a proper meal at night consistently made people sleepier in the early hours and increased gastric discomfort, without improving cognitive performance. Smaller, lighter eating across the night shift produced steadier alertness.
Meanwhile the wider research on meal timing is clear: eating more of your energy earlier, and finishing eating earlier in the day, improves glucose tolerance, insulin sensitivity and metabolic markers. A Monash University study led by Gloria Leung and Maxine Bonham found that a five-hour overnight fast during night shift shifted weight in a favourable direction without reducing total intake.
In practice: eat your main meal before your shift, not at 2am. Take a proper meal to work and eat it earlier in the shift — say within the first four hours. Then use a lighter snack (yoghurt, fruit, nuts, a sandwich) in the small hours rather than a full hot meal. And if you can, hold a genuine 5-hour fast window in the middle of the night, roughly 1am to 6am.
That's a big behavioural change for most people. Start with one shift a swing.
3. Drink more than you think, and not just water
Heat is the invisible performance killer in WA, and it's where FIFO workers most reliably come unstuck.
In summer, Pilbara temperatures routinely sit in the low-to-mid 40s. Sweat rates while working in that environment commonly run between 1 and 2 litres per hour, and can exceed that in heavy work with protective clothing. You cannot replace 8 litres of sweat with a few sips on smoko.
Watch your urine colour, not your thirst. Pale straw is the target. Apple juice means you're behind. Thirst is a lagging indicator — by the time you feel it, you're already down a few percent of body water, and even mild dehydration degrades cognitive performance, reaction time and endurance.
For long shifts in the heat, water alone is not enough. You lose sodium too, and drinking large volumes of plain water without replacing sodium can dilute your blood sodium. This is a real risk in industrial settings. A simple approach: water through the day, plus one electrolyte-containing drink per shift during hot weather, plus salt in your food. You don't need a sports drink with 30 grams of sugar — an electrolyte tab or a low-sugar electrolyte powder is enough.
4. Use caffeine properly, not constantly
Caffeine genuinely works. It improves alertness, reaction time and vigilance during night shift, and there's decades of evidence on it. It's also the most abused performance tool on site.
The problem is timing. Caffeine has a half-life of roughly five to six hours in most people, longer in some. A 3pm coffee means a meaningful amount in your system at 9pm. On a swing where you're trying to sleep at 10pm to be up at 4am, that's sabotage.
A structure that works:
One coffee on waking, before your shift
Optionally one more in the early part of the shift
Last caffeine 8 hours before your planned sleep — for a 9pm bedtime, that's 1pm
No caffeine during the 1am–6am window if you're trying to hold that fast
Never use caffeine to get through the drive home; it masks rather than reverses impairment
One more thing worth saying: if you need escalating amounts of caffeine and energy drinks to function, that's information. It usually means sleep debt has outrun your ability to compensate, and no amount of caffeine fixes that.
5. Go easy on the swing alcohol
This isn't a lecture — it's arithmetic. Alcohol on site is often the main social ritual, and it's also the thing most likely to wreck the sleep you just spent 12 hours earning. Alcohol reduces sleep latency but fragments sleep in the second half of the night, suppresses REM, and worsens sleep apnoea. If you're already in sleep debt, a few beers turns a manageable deficit into a dangerous one.
There's also the calorie side, which nobody enjoys hearing: a six-pack is roughly 2,000 kilojoules — about a full meal's worth. Across a two-week swing that's a meaningful amount of weight gain, and it tends to arrive exactly where FIFO workers notice it, around the middle.
If you're going to drink, keep it to the nights before a day off, keep it modest, and drink a glass of water between each one.
A working FIFO day
Here's what this looks like in practice. This is a template, not a prescription — adjust the portions to you.

The 2:1 roster: don't lose the swing on the break
Here's the pattern we see most often, and it's completely understandable.
You hold it together on swing. You eat reasonably, you're active, you're disciplined. Then you get home, and for seven days the entire structure disappears. No roster, no dining hall, no set times. You sleep badly, eat whatever's in the fridge, drink more, and by the time you fly back out you've undone two weeks of work in one.
The break is not a holiday from your body. It's the other half of the cycle.
Three things to protect on your days off:
Keep a wake time. Not 4.30am — but a consistent one, within an hour or so. Your body clock does not enjoy being reset by five hours every fortnight.
Keep the protein and vegetables. You don't need to meal prep like a bodybuilder. You need two meals a day with a protein and a vegetable in them.
Move. You go from a physically active job to sitting on a couch. That's a bigger energy swing than most people account for. A walk, a gym session, a swim — three times across the break is enough to matter.
The reverse-swing trap is real too: coming home and immediately flipping from night shift to daytime family life. Where you can, take the first day as a transition day. Sleep when you arrive, get up early the next day, and get outside into morning light — that's the strongest signal you can give your body clock.
The bag list
The most useful thing you can do is stop relying on the camp to be good. Pack this, every swing.
Whey or plant protein powder in single serves — the cheapest insurance against a low-protein day
Nuts and seeds in portioned bags, not a big bag you'll finish
Tinned tuna or salmon, a few tins
Protein bars — read the label, aim for 20 g protein and under 10 g sugar
Electrolyte tabs
A water bottle you actually like — 1 litre minimum, 2 better
Instant oats or a low-sugar muesli for the nights you can't face the dining hall
A small shaker
Eye mask, earplugs, magnesium glycinate if sleep is your weak point
What we see in clinic
Three patterns come up again and again with FIFO clients.
Weight gain of 3–6 kg a year, concentrated around the middle. Almost always driven by alcohol, late-night eating and the break, not by camp food being inherently bad.
Fatigue that isn't fixed by sleep. Very often low iron or low ferritin, vitamin D deficiency (common in night shift workers who rarely see the sun), or simply chronic under-fuelling. Worth a blood test rather than a supplement guess.
Gut symptoms that appear on swing. Constipation from low fibre and dehydration, or bloating from eating a large volume late at night. Both respond well to timing changes and fibre built up slowly.
Supplements worth considering — and the ones to skip
Be sceptical here, because FIFO workers are marketed to relentlessly.
Worth it, if you have the gap:
Vitamin D — 1,000–2,000 IU daily, especially if you're on nights. Get your level tested first if you can.
Creatine monohydrate — 3–5 g daily. It's the most evidence-backed supplement in existence for strength and lean mass, it's cheap, and it's particularly relevant if you're over 40 or training.
Magnesium glycinate — 300 mg at night if sleep is poor. Glycinate, not citrate or oxide, which will loosen your bowels.
Protein powder — a food, not a supplement. Use it when the alternative is no protein.
Iron — only if a blood test shows you need it. Iron is not a supplement to take on a hunch.
Skip: testosterone boosters, "fat burners", pre-workouts loaded with stimulants you'll still have in your system at bedtime, and anything promising to fix fatigue without asking why you're tired.
When to get proper help
Book in with someone if:
You're gaining weight every swing despite trying
You're exhausted in a way sleep doesn't fix
Your gut is a mess on site and fine at home (or the reverse)
You've been told your blood pressure, cholesterol or blood sugar is creeping up
You're relying on energy drinks, caffeine or alcohol to get through
You're training hard and not seeing results
These are all solvable, and none of them are solved by trying harder. They're solved by looking at what's actually happening across the whole cycle — bloods, sleep, timing, and what you're genuinely eating — and building something that survives contact with a real roster.

Frequently asked questions about FIFO nutrition
How do I eat healthy on a 2:1 roster? Eat protein at every meal, front-load your bigger meals earlier in the day, use the smaller plate at the buffet, keep a five-hour overnight fast where you can, and stop caffeine eight hours before sleep. Pack protein and snacks so you're not dependent on the dining hall.
Why do I gain weight on every swing? Usually three things: alcohol, eating a large meal late at night, and then losing all structure on your days off. Camp food itself is rarely the whole story.
What should I eat on night shift? Your main meal before the shift, a proper meal early in the shift, then something light across the small hours. Research shows large meals at 2am make you sleepier and increase gastric discomfort without improving performance.
Is it bad to eat at night on shift? It's not ideal — your body handles food less well at night — but it's not something to be frightened of. The practical answer is to keep night-time eating light, and to hold a fast window in the middle of the night if you can.
How much protein do I need for physical work? Roughly 1.2 to 1.6 grams per kilogram of body weight daily, spread across meals. For an 85 kg worker that's about 100 to 135 grams.
How much water should I drink in the Pilbara heat? It depends on your sweat rate, which can exceed 1–2 litres per hour in summer. Don't rely on thirst — check urine colour, and add electrolytes during long hot shifts rather than drinking plain water only.
Should I take supplements on FIFO? Vitamin D, creatine and magnesium glycinate have reasonable evidence for this population. Iron only if tested and low. Skip fat burners, testosterone boosters and stimulant pre-workouts.
How do I stop the 3pm wall? Usually it's blood sugar plus dehydration plus a low-protein breakfast. Eat protein at breakfast, drink more through the morning, and have a proper lunch rather than grazing.
Can a nutritionist help if I'm only home one week in three? Yes — telehealth works well for FIFO. We do the assessment while you're home, then build a plan for the swing that you can run from site.
