1. An apparatus for tracking caloric consumption and caloric expenditure of an individual, comprising:

  • at least two sensors adapted to automatically detect data when in proximity to said individual'"'"'s body, at least one of said sensors adapted to automatically detect data indicative of a first parameter of said individual, and at least one of said sensors adapted to automatically detect data indicative of a second parameter of said individual;

    a processor in communication with said sensors, said processor being programmed to use said data of the first parameter and the second parameter to derive at least one of caloric consumption data and caloric expenditure data of said individual wherein said derivation is based on an algorithm; and

    an I/O device in communication with said processor, said I/O device further adapted to at least one of enable said individual to enter information relating to calories consumed by said individual and to receive information relating to calories consumed by said individual, said I/O device comprising a display for displaying information, said information being based on at least one of said derived caloric expenditure data, entered information relating to calories consumed by said individual, received information relating to calories consumed by said individual, and said derived caloric consumption data,wherein said processor is further programmed to use both said data indicative of the first parameter of said individual and said data indicative of the second parameter of said individual to derive a type of activity in which said individual is engaged,wherein said algorithm is selected based upon said type of activity in which said individual is engaged; and

    wherein the at least two sensors comprise one of the combinations of;

    a heart rate sensor and a heat flux sensor, a heart rate sensor and a skin temperature sensor, a heart rate sensor and a GSR sensor, a body motion sensor and a heat flux sensor, a body motion sensor and a skin temperature sensor, and a body motion sensor and a GSR sensor.
