The diet issue with the A&W food sets menu in Malaysia is developed mathematically in this study. The goal of the model is to calculate the most calories from the A&W food menu sets that a person can eat each day and yet meet all their nutritional needs. All daily food set menus in this mathematical model satisfied a person's requirements for total calories, carbohydrates, protein, and fats. An integer linear programming model is proposed and solved using the Excel Solver method based on the diet problem.
