Fit for Duty: Evidence-Based Nutrition and Fitness Strategies for UK Security Officers

As a security officer, your body is your tool of the trade. Long hours, irregular shifts, and the need for constant vigilance can take a toll on your health. But fear not! We’ve dug deep into the latest research to bring you practical, science-backed strategies to keep you fit and healthy for your demanding job. Let’s dive in!

The Shift Work Challenge

First, let’s address the elephant in the room: shift work. A study published in the Scandinavian Journal of Work, Environment & Health found that shift workers have a 9% higher risk of developing type 2 diabetes compared to non-shift workers [1]. But don’t hang up your uniform just yet – we’ve got strategies to combat this.

Nutrition Strategies for Shift Workers

Shift work can disrupt your eating patterns, but with smart choices, you can stay energised and healthy. These evidence-based strategies will help you manage your nutrition effectively.

Time-Restricted Eating: 

Research from the Salk Institute suggests that limiting your eating window to 8-10 hours per day can improve metabolic health, even without changing what you eat [2].

Action Step: Try to eat all your meals within a 10-hour window, regardless of when your shift starts. Use a fasting app like Zero or FastHabit to track your eating windows.

Protein-Rich Foods: 

A study in the American Journal of Clinical Nutrition found that high-protein meals can improve alertness and reduce fatigue in shift workers [3].

Action Step: Pack protein-rich snacks like Greek yoghurt, boiled eggs, or nuts to keep your energy levels up during your shift.

Hydration is Key: 

Dehydration can impair cognitive function, which is crucial for security work. The European Journal of Clinical Nutrition recommends 35ml of water per kg of body weight daily [4].

Action Step: Invest in a good water bottle and set reminders to drink regularly throughout your shift.

Combat Fatigue-Induced Poor Eating: 

Research in the journal Nutrients shows that sleep deprivation can lead to increased cravings for high-calorie foods [5].

Action Step: Prepare healthy snacks in advance to avoid reaching for junk food when tired. Try veggie sticks with hummus or apple slices with peanut butter.

Budget-Friendly Nutrition: 

A study in the Journal of Nutrition Education and Behavior found that meal planning can reduce food costs and improve diet quality [6].

Action Step: Dedicate time on your day off for meal prep. Cook large batches of nutritious meals like chilli, stir-fries, or overnight oats to portion out for the week.

Fitness for Function

Security work can be physically demanding, requiring both strength and endurance. Here’s how to train smart:

Step Tracking: 

A study in the International Journal of Behavioral Nutrition and Physical Activity found that using a pedometer can increase physical activity by about 2,000 steps per day [7].

Action Step: Use your smartphone or a fitness tracker to monitor your steps. Aim for 10,000 steps per day, incorporating extra walks during breaks if needed.

High-Intensity Interval Training (HIIT): 

A study in the Journal of Physiology found that HIIT can improve both aerobic and anaerobic fitness in a time-efficient manner [8].

Action Step: Try this quick HIIT workout: 30 seconds each of burpees, mountain climbers, and bodyweight squats. Repeat 3 times with 1-minute rest between rounds.

Functional Strength Training: 

Research in the Journal of Strength and Conditioning Research shows that functional training can improve performance in job-specific tasks [9].

Action Step: Include exercises like deadlifts, farmer’s walks, and push-ups in your routine to mimic on-the-job movements.

On-Shift Exercises: 

A study in the Workplace Health & Safety journal suggests that even short bouts of exercise during work hours can improve health outcomes [10].

 Action Step: Try these discreet exercises during your shift:

• Calf raises while standing
• Isometric abdominal contractions
• Wall push-ups during bathroom breaks
• Seated leg lifts

Recovery is Crucial: 

A study in the International Journal of Sports Physiology and Performance emphasises the importance of sleep for physical recovery and cognitive function [11].

Action Step: Aim for 7-9 hours of sleep per day, even if it’s split into two sessions due to shift work.

Mental Fitness: The Overlooked Component

Your mental sharpness is just as important as your physical fitness. Here’s how to keep your mind in top form:

Mindfulness Meditation: 

A study in the Journal of Occupational Health Psychology found that mindfulness training can reduce stress and improve sleep quality in shift workers [12].

Action Step: Try a 5-minute mindfulness session before your shift using apps like Headspace or Calm.

Cognitive Training: 

Research in the journal Intelligence suggests that brain training games can improve cognitive function [13].

 Action Step: Spend 15 minutes a day on brain training apps like Lumosity or Peak.

Putting It All Together: Your Action Plan

• Plan Your Meals: Prep nutrient-dense, protein-rich meals for your shifts on your day off.
• Stay Hydrated: Aim for 35ml of water per kg of body weight daily.
• Track Your Steps: Use a smartphone or fitness tracker to aim for 10,000 steps daily.
• HIIT It Hard: Do a 15-minute HIIT workout 3 times a week.
• Train for Your Job: Incorporate functional strength training 2-3 times a week.
• Sneak in On-Shift Exercises: Do discreet exercises during quiet moments of your shift.
• Prioritise Sleep: Aim for 7-9 hours of quality sleep per day.
• Train Your Brain: Practise mindfulness and cognitive training daily.
