What are the four principles and mechanics of meal planning?

1. Variety: A healthy meal plan should include a variety of foods from all food groups, including fruits, vegetables, whole grains, lean proteins, and healthy fats. Eating a variety of foods ensures that your body gets all the nutrients it needs.

2. Balance: A balanced meal includes a combination of carbohydrates, proteins, and fats. Carbohydrates provide energy, proteins help build and repair tissues, and fats provide essential fatty acids and help you feel full. A balanced meal should also include a variety of vitamins and minerals.

3. Moderation: Eating in moderation means eating enough food to satisfy your hunger, but not so much that you feel stuffed. Overeating can lead to weight gain and other health problems.

4. Adequacy: An adequate meal plan provides your body with all the nutrients it needs. This means eating a variety of foods from all food groups, and eating enough food to support your activity level.
