    Suhoor & Iftar Meal Guidance
    Suhoor (Pre-dawn)
    • Low GI carbohydrates (oats, wholegrains)
    • High-protein foods (eggs, yoghurt)
    • Plenty of water
    • Avoid salty or sugary foods
    • Eat as late as permitted
    Iftar (Sunset)
    • Break fast with dates + water (traditional)
    • Avoid large immediate portion
    • Balanced meal 30-60 min after
    • Limit fried/high-sugar foods
    • Hydrate well in non-fasting hours

    When to break the fast: If blood glucose falls below 70 mg/dL (3.9 mmol/L) or rises above 300 mg/dL (16.6 mmol/L), the fast should be broken. Blood glucose testing does not invalidate the fast.

    How This Works

    This calculator is based on the IDF-DAR Practical Guidelines for people with diabetes who wish to fast during Ramadan. The IDF-DAR (International Diabetes Federation - Diabetes and Ramadan International Alliance) scoring framework assigns risk points:

    Base score (same as general fasting) + Ramadan modifiers:
    + Fasting hours >16h -> +1 point
    + No BG monitoring available -> +2 points
    + No pre-Ramadan counselling -> +1 point
    + First Ramadan with diabetes -> +1 point

    The IDF-DAR guidelines emphasise that many Muslims with well-controlled diabetes can fast safely with proper preparation, medical consultation, and an agreed monitoring and management plan.
