A system comprising a portable medical apparatus (30, 32) made up of at least two devices adapted to measure eating rate utilized to teach persons to eat according to a predetermined graphic eating curve (10, 24) displayed on a screen, wherein it comprises: a first pocket portable device with a screen storing said predetermined graphic eating curve (10, 24) in a memory, said first device having cellular phone capability and remote near field radiation capabilities for communication with a related second device; said related second device being a portable scale adapted to communicate with said first device, having cellular phone capability through similar remote near field radiation communication capabilities as said first device; and the system is adapted, during the duration of a scale measurement session, to weigh food on said scale, and transmit the food weight to said first device through said near field radiation when food is removed from said scale by a person eating the food, and through means of software residing in said first device to store the amount of food removed during a session in said memory, to display the weight of food removed as a measurement point on said screen when it is removed from said scale to make up a real time graphic eating curve to be compared with said predetermined eating curve (10, 24); and the system further comprises a software means adapted to transmit said stored session through said first device cellular phone capabilities through a cellular signalling system (44, 46, 48) to a remote server for registration, and a means in said server being able to send adapting instructions to said first device regarding what predetermined graphic eating curve (10, 24) to be utilized from arbitrary places due to previous registrations of real time graphic eating curves characterized in that. said scale has a docking station for said first device, whereby at least the screen is visible to a person eating from said scale. a first pocket portable device with a screen storing said predetermined graphic eating curve (10, 24) in a memory, said first device having cellular phone capability and remote near field radiation capabilities for communication with a related second device; said related second device being a portable scale adapted to communicate with said first device, having cellular phone capability through similar remote near field radiation communication capabilities as said first device; and the system is adapted, during the duration of a scale measurement session, to weigh food on said scale, and transmit the food weight to said first device through said near field radiation when food is removed from said scale by a person eating the food, and through means of software residing in said first device to store the amount of food removed during a session in said memory, to display the weight of food removed as a measurement point on said screen when it is removed from said scale to make up a real time graphic eating curve to be compared with said predetermined eating curve (10, 24); and the system further comprises a software means adapted to transmit said stored session through said first device cellular phone capabilities through a cellular signalling system (44, 46, 48) to a remote server for registration, and a means in said server being able to send adapting instructions to said first device regarding what predetermined graphic eating curve (10, 24) to be utilized from arbitrary places due to previous registrations of real time graphic eating curves characterized in that. said scale has a docking station for said first device, whereby at least the screen is visible to a person eating from said scale.
