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.

A method for monitoring food consumption in a subject, comprising:
