First Claim
1. A method for deriving and reporting the calories consumed by an individual, comprising:
- associating at least one physiological sensor with the body of said individual;
continuously collecting sensor output signals from said at least one physiological sensor for a period of time from said individual;
collecting quantitative physiological data of said individual related to a metabolism of said individual;
providing at least one mathematical operation relating to an association of said metabolism of said individual with said sensor output signals, the at least one mathematical operation stored in a non-transitory memory circuit accessible to a processor in communication with the at least one physiological sensor;
deriving values of said calories consumed by said individual from said sensor output signals by applying said at least one mathematical operation;
modifying said at least one mathematical operation to form at least one modified mathematical operation based upon said derivation of said values of said calories consumed by said individual, such that said derived values of calories consumed is consistently equivalent to at least one of said metabolic data and observed physiological data;
deriving the values of calories consumed by said individual by applying said at least one modified mathematical operation to said sensor output signals; and
deriving the energy expenditure of said individual from said quantitative physiological data related to the metabolism of said individual, said quantitative physiological data stored in said memory circuit, under both eating and fasting conditions for said individual.

Abstract
Various methods and apparatuses for measuring a state parameter of an individual using signals based on one or more sensors are disclosed. In one embodiment, a first set of signals is used in a first function to determine how a second set of signals is used in one or more second functions to predict the state parameter. In another embodiment, first and second functions are used where the state parameter or an indicator of the state parameter may be obtained from a relationship between the first function and the second function. The state parameter may, for example, include calories consumed or calories burned by the individual. Various methods for making such apparatuses are also disclosed.
