Abstract: The present invention provides for a system and method of partitioning of macronutrients (carbohydrates, vegetables, dairy, proteins and fats) of each food type into its macro-components (fruit, vegetables, dairy, carbohydrates, proteins and fats) with their own distinct nutrient profile to consistently achieve predefined calories and associated macronutrient ratios. The present invention includes a set of unique processes and methods for establishing food pattern modeling in which selection of foods is based on calculated nutrient values.
