Follow the Prophetic tradition: break your fast with dates (for instant energy and potassium) and water. Then, after performing Maghrib prayer, have your main meal. This pause allows your digestive system to gently "wake up" and signal satiety to your brain, preventing you from overeating. A balanced main meal using the plate method (vegetables, protein, complex carbs) will then provide sustained nourishment without the bloating or lethargy that comes from eating a large meal all at once.
