Choose fruits, vegetables and lean proteins like fish or chicken, as well as whole grains such as brown rice or quinoa. Try to avoid processed foods, sugary snacks, and fried items. Pack your lunch in reusable containers and bring along some cutlery for easy eating. Make sure to include plenty of fluids, such as water or juice, to stay hydrated throughout the day.
