⏰ How Your Body Uses Sugar Through the Day

🌙 12 AM – 6 AM

Liver & muscles are consuming sugar. Sugar levels naturally drop. Long-acting insulin helps maintain steady levels overnight.

🌅 6 AM – 9 AM

Body starts releasing stored sugar (dawn phenomenon). Long-acting insulin is critical here to prevent morning spikes.

💪 9 AM – 12 PM

After gym/activity, muscles are consuming sugar again. Good time for controlled carb intake.

🍛 12 PM – 4 PM

Only NovoRapid works here. Wheat roti peaks after ~3 hours. Time your insulin accordingly.

🌆 4 PM – 12 AM

Evening meals & snacks. Calculate carbs and take NovoRapid units accordingly.
