Patent ID: 8647273

Claim:
A method for assisting a subject to manage a weight of the subject, comprising the steps of: transmitting a series of separately transmitted electromagnetic signals over a range of distinct frequencies from a transmitter through a finger of the subject to a receiver to create a series of corresponding spectral data sets including each of the separately transmitted electromagnetic signals received by the receiver; developing the series of corresponding spectral data sets into one or more composite spectrograms including each of the separately transmitted electromagnetic signals received by the receiver; analyzing the one or more composite spectrograms to recognize a series of patterns within the one or more composite spectrograms that directly represent a glucose level in the subject; repeating the steps of transmitting, developing, and analyzing to obtain a series of glucose levels in the subject over a period of time; and utilizing the series of glucose levels to determine a record of caloric intake and caloric output that will assist the subject in managing the subject's weight of the subject.
