SYSTEMS AND METHODS FOR DETERMINING CALORIC INTAKE USING A PERSONAL CORRELATION FACTOR

Systems and methods are provided for determining an individual's personal correlation factor and, using the personal correlation factor, determining the individual's caloric intake. A method for determining a personal correlation factor includes determining a body composition change over a calibration period, converting the body composition change to an equivalent energy value, and dividing the equivalent energy value by a net caloric value for the same calibration period, wherein the net caloric value includes a caloric expenditure less a caloric intake. A method for determining a subsequent caloric intake includes converting a body composition change to an equivalent energy value, dividing the equivalent energy value by the personal correlation value, and adding to this quotient the individual's caloric expenditure, wherein each step is performed using a processor.
