Method and apparatus for identifying and reporting a physiological condition of an individual utilizing physiological and contextual parameters

A wearable device for identifying and reporting a cumulative physiological condition of an individual, comprising:

• at least one wearable physiological sensor for generating an electronic output in the form of a sensor output;
• a memory circuit containing stored mathematical algorithms for an identification of a particular cumulative physiological condition of said individual from said sensor output, said particular cumulative physiological condition selected from the group consisting of fatigue, ketosis, acute dehydration, drowsiness, edema, hypertension, shock, drowsiness, ovulation, fever, anemia and hypothermia, said mathematical algorithms for the identification of said particular cumulative physiological condition of said individual being derived from a previous sensor output compiled during a period of time that said particular cumulative physiological condition was known to have existed in said individual;
• a processor in electronic communication with said sensors and said memory circuit, the processor executing said stored mathematical algorithms using said sensor output to generate an output that identifies the presence of said particular cumulative physiological condition, wherein said particular cumulative physiological condition is fatigue and wherein said fatigue is identified using two functions of the stored mathematical algorithms, the two functions comprising a first function and second function for measuring total energy expenditure (TEE), the first function differing from the second function by an ability to measure a thermal effect of food (TEF), wherein the TEE comprises a sum of energy expenditures, TEE=BMR+AE+TEF+AT, wherein BMR is basal metabolic rate, an amount of energy expended by a body during rest, AE is activity energy expenditure, an amount of energy expended during physical activity, TEF is thermic effect of food, an amount of energy expended while digesting and processing food that is eaten, and AT is adaptive thermogenesis;
• and
• a display, in electronic communication with said processor which outputs said identification.
