Diet Watch

A diet watch includes a housing with an adjustable wristband attached thereto, at least one accelerometer and/or gyroscope sensor and/or magnetometer disposed within the housing, a processor disposed within the housing and operatively coupled to the at least one accelerometer and/or gyroscope sensor and/or magnetometer, and a feedback device coupled to the processor. The at least one accelerometer and/or gyroscope sensor and/or magnetometer provides a signal related to an orientation and movement of a user's hand in space. The processor uses the signal from the at least one accelerometer and/or gyroscope sensor and/or magnetometer to determine that a bite was taken by the user and starting a timer to countdown a preset time interval. The feedback device provides an indication to the user that another bite of food may be taken after the preset time interval has elapsed.
