Metabolic energy monitoring system
First Claim
1. A method for determining a metabolic status over a period of time, the method comprising:
- using a sensor to make at least one determination of a body composition change encompassing said period of time;
making at least one determination of a kcal energy expenditure encompassing said period of time; and
making at least one determination of an energy intake corresponding to said period of time;
wherein the determination of the body composition change includes a determination of a fluid mass change, andwherein said determination of the body composition change is utilized by circuitry for a determination of an energy balance corresponding to said period of time, and wherein the determination of the energy balance does not include the fluid mass change, andwherein the determination of said energy balance is utilized in conjunction with the determination of the kcal energy expenditure in making the determination of the energy intake.

Abstract
A metabolic energy monitoring system having one or more physiological measurement platforms and displays enabling the calculation and display of energy balance, kilocalorie energy expenditure and kilocalorie intake is described. In preferred embodiments, the system utilizes one or more on-body monitoring platforms to enable measurement of change in body composition and kilocalorie energy expenditure over a period of time thereby enabling a comparator to calculate net energy balance over this period of time and to calculate kilocalorie intake over this same period of time. Such data may then be displayed on a display device in wireless communication with the on-body monitoring platform to provide the user of the system with useful information and guidance in weight management applications.
