Shift work changes how your body processes food.
Firefighters don’t operate on normal circadian rhythm — and that affects metabolism.
What Shift Work Does to the Body
Irregular sleep disrupts:
-
Hormone regulation
-
Insulin sensitivity
-
Appetite control
-
Recovery
This increases risk for:
-
Weight gain
-
Energy crashes
-
Elevated blood pressure
Nutrition must adapt to shift reality.
Why Late-Night Eating Matters
Eating large, high-sugar meals overnight leads to:
-
Blood sugar spikes
-
Energy crashes
-
Poor sleep after calls
Instead choose:
-
Protein-based snacks
-
Fruit
-
Greek yogurt
-
Nuts
Small upgrades make a big difference.
Stabilizing Energy on 24-Hour Shifts
To avoid crashes:
-
Spread protein evenly across meals
-
Choose complex carbs
-
Stay hydrated
-
Avoid excess energy drinks
Firefighter performance depends on energy stability.
