Nutrition researchers and dieticians use indirect measures to measure food intake, such as food recalls. With a meter, we can measure actual food intake during the meal and also people's eating behavior. The main advantage of the meter is that we can measure more precisely how much people eat with little effort from consumers or patients.
This protocol shows and explains a new technology-based dietary assessment method. The method consists of a dining tray with multiple built-in weighing scales and a video camera. The device is unique in the sense that it incorporates automated measures of food and drink intake and eating behavior over the course of a meal.
