The Shift Work Health Trap (And How to Escape It)
Let’s face an uncomfortable truth: shift work can rapidly deteriorate your mental and physical health if left unchecked.
During a stint in the music and entertainment industries, I experienced firsthand how shift work can derail your health. Between late-night gigs, abundant catering with tempting but unhealthy options, and barely having time to think about nutrition—I watched my energy plummet and my waistline expand. The combination of irregular hours, overindulgent food, and limited time for self-care created the perfect storm for physical decline.
But here’s the good news: it doesn’t have to be this way.
The health and fitness industry has overcomplicated what should be straightforward. When you’re already juggling irregular sleep patterns and the unique stressors of shift work, the last thing you need is conflicting advice about keto, paleo, carnivore, or whatever new diet is trending on Instagram.
Instead, let me offer you the simplified blueprint that helped me shed 15kg and maintain high energy levels despite working shifts that would have crushed me otherwise.
The Shift Worker’s Nutrition Protocol
The foundation of physical optimization for shift workers comes down to three principles:
- Energy balance (calories in vs. calories out)
- Strategic carbohydrate timing
- Intermittent fasting adapted to your shift pattern
That’s it. No fancy supplements. No elimination diets. No complicated meal plans requiring ingredients you can’t pronounce.
Despite what supplement companies want you to believe, weight management fundamentally comes down to calories in, calories out. This isn’t controversial—it’s thermodynamics.
What is important is making this principle work within the constraints of a shift worker’s life.
The key is creating systems that make calorie control effortless rather than another source of stress. Here’s my approach:
- Batch cooking weekly (This can be difficult on a rolling roster – I compensate by having a couple of steaks in the freezer at all times waiting to be thrown in the sous vide and combined with some green lentils for a quick ‘don’t need to think about it’ meal if I am caught out without prep)
- Pre-logging meals in MyFitnessPal before the shift week begins
- Strategic meal timing based on shift pattern (more on this below)
The Slow-Carb Advantage for Shift Workers
The timing and type of carbohydrates you consume can dramatically impact your energy levels during long shifts. Through extensive self-experimentation, I’ve found that low-glycemic carbs consumed 2-3 hours before starting a shift provide the most stable energy without the crashes.
My go-to sources:
- Sweet potatoes
- Black beans
- Lentils
- Steel-cut oats
These slow-burning carbs prevent the blood sugar roller-coaster that leads to fatigue, especially during those critical 2-4 AM hours when your body is fighting its natural circadian rhythms. The last thing you need is to polish off a big portion of ‘spagbol’ at 3am and end up in noddy land.

Intermittent Fasting Tailored to Shift Work
A 16:8 fasting protocol (16 hours fasting, 8 hours eating) has been my secret weapon for maintaining alertness and controlling weight. However, standard fasting advice doesn’t work for shift workers.
Instead of following clock-based fasting windows, I anchor my eating window relative to when my shift begins:
Day Shift Routine:
- Begin eating 2 hours after waking
- End eating 3 hours before end of shift
Night Shift Routine:
- Begin eating 2 hours before shift starts
- End eating 2 hours before planned sleep time
This approach provides metabolic flexibility while preventing the energy crashes that come from poor meal timing during shifts.
Enter Mike Mentzer’s Heavy Duty – The Shift Work Training Hack
The conventional wisdom of needing 4-5 gym sessions per week is particularly problematic for shift workers with unpredictable schedules. This is where Mike Mentzer’s Heavy Duty training methodology becomes invaluable.
Mentzer’s approach centers on a few core principles that are perfect for shift workers:
- Training to momentary muscular failure
- Drastically reduced training frequency
- Brief but intense workouts
- Emphasis on recovery over volume
After implementing this approach, I’ve maintained strength and muscle mass with just 2-3 weekly sessions of 30-40 minutes each—a game-changer when your schedule is in constant flux.
NOTE: I do not weight train during nightshift swings – I place higher value on rest and recovery during these periods and opt for a late afternoon walk or other form of cardio with my partner, both to stay energised and to also use it as a form of couples time so we aren’t ships passing in the night when I am on the nightshift swing.

Permission to Be Human
A critical part of all of this – not just diet but overall is remember to treat yourself, there is nothing wrong with a cheat day as long as you can self regulate and not go overboard; I could get into the stoic philosophy of why both struggle and reward are the building blocks upon which man builds his life but you’re falling asleep already.
The key is building systems that make the healthy choice the default most of the time, so the occasional indulgence remains just that—occasional.
Go out and have a couple beers with the boys on your off day, have bottomless brunch with the girlies, eat a pizza while you watch the footy. We’ll talk about looking after mental health a little later on.
Remember: This isn’t about perfection. It’s about implementing systems that make health optimisation automatic, even when your work schedule is anything but regular.
Until next time.
