Nutritionist Sarah Di Lorenzo provides strategies to combat festive burnout through targeted nutrition, focusing on protein-rich foods, complex carbohydrates, and magnesium sources. She emphasises maintaining energy levels and mental clarity during the holiday season while still allowing complete indulgence on Christmas Day. Key recommendations include incorporating eggs, Greek yoghurt, nuts, leafy greens, and whole grains throughout the day to support neurotransmitters, immunity, and digestive health.
