Abstract: A method and apparatus provides a service based on biometric information. A bioelectrical impedance of a user is measured at a first time point to obtain a first value representing biometric information of the user. At least one processor predicts the biometric information of the user at a third time point subsequent to the first time point to obtain a third value, based on the first value representing biometric information of the user at the first time point and a second value representing the biometric information at a second time point prior to the first time point. The processor calculates a difference between a fourth value representing a target related to the biometric information of the user, input by the user in advance, and the third value. Information regarding a health management service is output based on the difference between the fourth value and the third value.
