Abstract
The present disclosure provides a dynamic intelligent weight management system and a dynamic intelligent weight management method. In this method, a user device executes an application program to receive and send the user’s personal data and target weight to the server, so that the server can calculate an estimated time required to reach the target weight. The user device is based on an energy balance model to periodically process energy records pertaining to energy intake and expenditure, and then sends the energy records to the server, so that the server can determine whether the target weight can be reached at or before the estimated time according to the energy records.
