Patent ID: 8641612

Claim:
A method for predicting a caloric intake of an individual utilizing external sensors associated with a body of said individual, comprising: collecting sensor output signals from at least two sensors associated with the body of said individual and in a housing, said housing mounted on skin of said individual, at least one of said at least two sensors being a physiological sensor generating data indicative of a caloric expenditure of the individual; computing the caloric intake of said individual for a period of time using collected output signals from the at least two sensors; compiling said computations of said individual's caloric intake for said period of time into a first data set; creating a series of mathematical operations for derivation of a predicted caloric intake of said individual from said collected sensor output signals; using a processor to: (i) derive a series of predicted caloric intake values of said individual from said collected sensor output signals by applying said series of mathematical operations in order to form a second data set; (ii) compare said first data set with said second data set; (iii) modify said series of mathematical operations to form a modified series of mathematical operations in accordance with said comparison of said first and second data sets, such that said predicted caloric intake for said period of time is correlated with said computed caloric intake for said period of time; and computing said caloric intake of said individual for said period of time solely by deriving said caloric intake of said individual from said collected sensor output signals by utilizing said modified series of mathematical operations.
