A patient management system for assisting in the treatment of individuals having metabolic disorders is provided. More specifically, the present invention provides a system and method for dynamically calculating multiple parameters and conditions based on various attributes (e.g., disorder, age, weight and gender) to establish required nutritional goals specific to a particular metabolic patient. Thereafter, a unique exchange based mechanism is employed to simplify food breakdown and corresponding nutritional values to construct an accurate dietary prescription plan for meeting those required nutritional goals.
