598925 Disclosed is a medical apparatus made up of at least two devices adapted to measure eating rate (12). The apparatus is used to teach people to eat according to a predetermined graphic eating curve (10) displayed on a screen. The apparatus includes a first device with a screen storing the predetermined graphic eating curve (10) in a memory. The first device also has at least one of remote near field radiation and wire capabilities for communication with a related second device. The related second device is a scale adapted to communicate with said first device. The second device also has at least one of remote near field radiation and wire communication capabilities adapted to said first device. The apparatus also includes means in stored in the memory for automatically calculating equations for predetermined eating curves (10) based on data obtained from a cumulative food intake in a control meal through an introductory curve followed by training curves. The cumulative food intake is fitted to a quadratic equation y=ax2+bx+c, where the parameter &ldquoy&rdquo represents food intake, &ldquoa&rdquo represents a change in the slope of the curve over time x minutes, &ldquob&rdquo represents a constant slope of the curve over time - the initial rate of eating - and &ldquoc&rdquo represents food intake at the start of a meal. The introductory curve has the same properties as the cumulative food intake obtained in the control meal.
