The term FOOD PLAN can be summarized as a DIET, which is a four letter word. A DIET is an eating plan that is designed to achieve a specific health or weight-related goal. It typically involves reducing the amount of food consumed and/or increasing the amount of exercise done. Different diets may focus on different types of foods, such as low-fat, low-carbohydrate, or high-protein. Additionally, some diets may involve fasting or eliminating certain food groups altogether.
