The invention further provides methods for monitoring food consumption of a subject. ## Claims ### Claim 1 A system for monitoring food consumption of a subject, comprising: a registration system configured to receive food data comprising nutrients and/or calories contained in one or more food items served to the subject; an intake detection system configured to detect consumption of said one or more food items, thereby generating real-time food consumption data; and a tracking and analysis system configured to receive food data from said registration system and consumption data from said intake detection system, and configured to utilize said food data and said consumption data to calculate a total amount of one or more nutrients and/or calories consumed by the subject. ### Claim 2 (depends on 1) The system of claim 1, wherein the intake detection system detects consumption of one or more food items by measuring a change of weight; a change of volume; a change in the amount of a detectable label present in the food item; or mouthfuls of food taken by the subject. ### Claim 3 (depends on 2) The system of claim 2, wherein the intake detection system comprises one or more sensing devices configured to detect a change in weight in one or more food items served to the subject as it is consumed by the subject. ### Claim 4 (depends on 3) The system of claim 3, wherein the intake detection system comprises a tray, wherein the tray comprises one or more sensing devices configured to detect a change in weight of one or more food items on the tray as said one or more food items are consumed by the subject. ### Claim 5 (depends on 4) The system of claim 4, wherein the tray comprises a plurality of discrete regions, and wherein the one or more sensing device is configured to detect a change in weight occurring in one or more of said plurality of discrete regions. ### Claim 6 (depends on 3) The system of claim 3, wherein the sensing device comprises a weighing device operably connected to a sensor. ### Claim 7 (depends on 1) The system of claim 1, wherein the system comprises a user interface configured so that a user can input one or more type of information selected from the group consisting of food data, nutritional consumption goals, and data concerning the weights of utensils and food vessels used to serve one or more food items. ### Claim 8 (depends on 1) The system of claim 1, wherein the system comprises a display device operably linked to the tracking and analysis engine and configured to display an amount of one or more nutrients and/or calories consumed by the subject. ### Claim 9 (depends on 1) The system of claim 1, wherein the intake detection system further comprises an initiator configured to detect the commencement of food consumption. ### Claim 10 (depends on 1) The system of claim 1, further comprising one or more external data sources operably connected to the registration system and/or one or more data repositories operably connected to the tracking and analysis system. ### Claim 11 (depends on 1) The system of claim 1, further comprising a control device configured to receive data from the tracking and analysis system. ### Claim 12 (depends on 11) The system of claim 11, wherein the control device is a drug delivery system which delivers a drug to the subject based upon the amount of one or more nutrients consumed by the subject as calculated by the tracking and analysis system. ### Claim 13 A food tray comprising: a data interface configured to receive food data associated with one or more food items on the food tray; a sensing device configured to detect a change in weight of one or more food items on the tray, thereby generating real-time food consumption data; an analysis module configured to analyze the food data and the real-time food consumption data to generate consumption analysis data providing the total amount of one or more nutrients and/or calories consumed by the subject; and a memory configured to store at least one of the food data, the consumption data, and the consumption analysis data. ### Claim 14 (depends on 13) The food tray of claim 13, comprising a plurality of discrete regions, and a plurality of sensing devices, wherein each of the plurality of sensing devices is configured to detect a change in weight in one or more of the plurality of discrete regions. ### Claim 15 (depends on 13) The food tray of claim 13, wherein the sensing device comprises a weighing device operably connected to a sensor. ### Claim 16 (depends on 13) The food tray of claim 13 wherein the tray comprises two or more foldable segments, each segment comprising a scale, and wherein the foldable segments are configured so that the tray is convertible between an open and a folded configuration. ### Claim 17 A method for monitoring food consumption in a subject, comprising: receiving and storing food data comprising nutrients and/or calories contained in one or more food items served to the subject; detecting the initiation of food consumption by the subject; obtaining real-time food consumption data; processing the food data and the real-time food consumption data to calculate consumption analysis data including a total amount of one or more nutrients and/or calories consumed by the subject. ### Claim 18 (depends on 17) The method of claim 17, wherein food consumption data is determined by detecting a change in weight in one or more food items served to the subject as it is consumed by the subject. ### Claim 19 (depends on 17) The method of claim 17, further comprising receiving and storing data concerning consumption goals for one or more nutritional component, and utilizing said data in combination with the consumption analysis data to calculate progress towards the goal. ### Claim 20 (depends on 17) The method of claim 17, further comprising sending information or instructions to a control device, wherein the control device is a drug delivery system which delivers a drug to the subject based upon the amount of one or more nutrients consumed by the subject.
