PROBLEM TO BE SOLVED: To provide information which encourages a user to continue a lifestyle improvement program by using the past weight loss results of participants.SOLUTION: The system holds information on health guidance provided to a participant during a guidance period. The information on health guidance includes information showing whether the participant is in a health guidance period or not, information showing whether the participant achieves the goal upon completing the guidance period, first information which does not vary by an intention of the participant and second information which varies according to an intention of the participant. After acquiring a predetermined instruction, a calculator extracts second participants who completed the guidance period and achieved the goal when completing it from the participants and compares the first information of a first participant who is in the guidance period with the first information of each of the second participants to calculate a comprehensive similarity degree. The calculator compares the second information of the first participant with the second information of each of the second participants to calculate a comprehensive inconsistency degree. Based on the calculated comprehensive similarity degree and comprehensive inconsistency degree, data for displaying information on the first participant and each of the second participants is generated.
