Gut‑Friendly, High‑Protein Lunchboxes: 10 Real‑Food Ideas

Lunch that actually powers the second half of your day.

A lunchbox should keep you alert, not drowsy. That means a protein anchor, colour for fibre and micronutrients, and smart carbs for sustained energy.

This expanded list gives you flexible boxes you can prep in minutes, perfect for offices, classrooms, or training days.

The perfect lunch formula

This formula consists of 4 parts:

• Protein anchor:
  • 20–30g adults; 15–25g teens.
  • Keeps you full for longer - stops you reaching for those 3 pm biscuits.
    
    
• Colour & crunch:
  • Veg/fruit for fibre (carrot, pepper, berries, apples).
  • Essential fibre & micro nutrients to keep you on top of life.
  • Berries & fruits are a great way to curb sweet tooth cravings 
    
    
• Smart carb:
  • Oatcakes, quinoa, rice, potatoes (adjust to activity level).
  • Be smart - High activity day, adjust the quality to reflect this
    
    
• Healthy fat:
  • Olive oil, avocado, nuts/seeds for satiety and absorption.
