1. A system for remote monitoring of food intake and physical activity in a human subject, comprising:
- a device for remote monitoring of food intake and physical activity in a subject comprisinga housing having a first side and a second side, wherein when the device is worn by the subject, the first side is proximal to the subject and the second side is distal to the subject;
one or more physiological sensors contained within the housing, contained within or connected to the housing, wherein the physiological sensors are selected from the group consisting of a microphone, an oxygen saturation sensor, a heart rate monitor, and an electrode;
a sensor for determining location, the sensor contained within the housing;
a motion sensor contained within the housing;
a video camera contained within the housing;
a data transfer interface contained within the housing and connected to the sensors and the video camera; and
one or more power supplies contained within the housing;
a computer; and
a data communication device for transmitting data obtained from the device to the computer,wherein the computer is programmed or configured to perform a process for recognizing a swallowing event by a person wearing the device and turning on video recording by the device when data is received by the device that corresponds to a swallowing event, the computer also programmed or configured to perform one or more processes for recognizing a food item, recognizing a physical activity, and determining a dimension of a food item in video data obtained from the video camera and for characterizing or quantifying physical activity of a subject wearing the device in data obtained from one or more of the video camera, the physiological sensor, the sensor for determining location, and the motion sensor.

Abstract
Electronic systems, devices and methods are provided to accurately measure both food intake and physical activity in a subject. A device is provided to be placed on a subject which records video as well as other physiological and/or environmental data. Video data can be analyzed along with other data obtained by the device to determine food consumption and physical activity of the subject, much of which is accomplished by automated computer-implemented processes.
