When creating a balanced meal plan, several factors should be considered, including nutrient variety, portion sizes, and individual dietary needs. A successful meal plan incorporates foods from all food groups to ensure the intake of essential vitamins and minerals, emphasizing whole grains, lean proteins, fruits, and vegetables. Portion control helps maintain appropriate calorie levels for individual goals, whether for weight loss or maintenance. Personal preferences, food allergies, cultural aspects, and lifestyle must also be taken into account for long-term adherence to the meal plan.
