The Food Exchange Diet Planner is a user-friendly software designed for food experts and experienced individuals, allowing them to build and evaluate diet plans founded on the food exchange system.

Firstly, the average daily energy requirements of the person for whom the diet is planned must be defined in terms of calories. This value can be suggested by the program based on the person's age, height, weight, and activity level.
Secondly, the user can define the percentages of the three macronutrients (carbohydrates, protein, and fat) that the diet should consist of. Alternatively, the user can choose a set of predefined percentages for different diet styles such as the balanced diet, zone diet, Mediterranean diet, etc.
Finally, the user specifies the preferred daily servings for three food groups, namely dairy, fruits, and vegetables. This information can be adjusted to reflect the personal preferences of the person or a predefined set of diet types.
The program then calculates the daily number of servings for the other food groups based on the given constraints. Additionally, the program contains a calorie calculator that can compute daily energy needs based on the user's weight, height, and physical activity level.
In summary, the Food Exchange Diet Planner is an easy-to-use, effective software program for creating and testing various diet plans based on the food exchange scheme.
