## Abstract

A weight management system comprised of a body worn device which interfaces periodically with a computer. The established weight goals of the user are translated by the computer into daily activity targets and downloaded into the device. The device monitors the user's activity, offering progress status toward the daily activity target. Further, the device alerts the user of excessive sedentary periods which depress metabolic indicators. The activity targets, allowed length of sedentary periods and suggested activities to reach goal are specific to the individual based on their biometrics and living environment. The computer provides historical tracking of activity for motivational and coaching purposes.

## Claims

### Claim 1

A device for predicting a resting metabolic rate of a person having a weight, height, age, and gender, the device comprising:
a controller having one or more inputs, the controller using resting diastolic and systolic blood pressure measurements as independent variables in a predictive equation, wherein the predictive equation is
RMR=K1*W*(1−K2*W/H2)+K3*H−K4*AK5*G+K6−*D−K7*S+K8
wherein RMR is the resting metabolic rate of the person, W is the weight of the person, H is the height of the person, A is the age of the person, G is the gender of the person, D is the diastolic blood pressure of the person, S is the systolic blood pressure of the person, and K1, K2, K3, K4, K5, K6, K7, and K8 are constants.
