Abstract
Systems and methods for approximating caloric energy intake and/or macronutrient composition using thermogenesis. The system may include one or more sensors for tracking body temperature over a period of time, and may include a processor configured to determine caloric energy intake and/or macronutrient composition based on body temperature. The system may be configured to normalize body temperature readings to compensate for factors other than thermogenesis that might affect core body temperature. The system may include one or more sensors for measuring normalization factors, and a processor for normalizing raw body temperature readings based on the measured normalized factors. The method may include the steps of: (a) collecting body temperature data, (b) normalizing the raw body temperature data and (c) determining caloric energy intake and/or macronutrient composition from the normalized data. The system may be configured to account for user calibration data when characterizing macronutrient composition.
