The invention relates to a method and device for weight management of humans. First, the user's initial weight and his target weight are received via a user interface of the device, then food intake amount and exercise instructions to be presented via the user interface of the device are generated on the basis of the difference between the user's initial weight and his target weight. In addition, the user's energy expenditure is generated with the device and the user's food intake amount is received via the user interface of the device. Further, the user's current weight is received via the user interface and a change in the user's weight is generated with the device. Further still, the food intake amount and/or exercise instructions to be presented via the user interface of the device are modified with the device on the basis of the change in the user's weight.
