1. An ambulatory metabolic monitoring system comprising:
- microphone means to be mounted on a subject over the muscles of mastication;
a keyboard to be carried by the subject for entering descriptions of the types and quantities of foods and drink consumed by the subject;
first sensor means to be mounted on the subject for generating acceleration signals (Z) indicative of vertical motions of the subject;
EKG sensor means to be mounted on the subject for generating EKG signals relating to the cardiovascular state of the subject;
signal storage and processing means coupled to said sensor means and to said keyboard for storing and processing the accelerations signals (Z) from said first sensor means for successive time periods, for storing and processing EKG signals from said KEG sensor means for said successive time periods, and for storing and processing signals from said microphone means and from said keyboard for said successive time periods; and
computer means connected to said signal storage and processing means and responsive to output signals therefrom for producing data relating to the walking/running mode step rate and the food and drink intake and heart rate of the subject for each of said successive time periods.

Abstract
An ambulatory metabolic monitoring system which includes a number of sensors which are adapted to be mounted on a subject for generating electric signals relating to various physical activities of the subject, and well as EKG signals, and signals indicative of the food and drink consumed by the subject, and which also includes a signal storage and processing unit which is carried by the subject and which is connected to the various sensors so that data related to the various physical activities and food and drink consumption of the subject may be stored and processed to provide information useful in monitoring the metabolic state of the subject.
