Body weight is an important indicator of a person's health status. In this study, we evaluated the effectiveness of the body weight management system, HIMS (Health Improvement and Management System)-Diet, which instantly provides users with feedback on their measured weight using the database that stores the user.customized information.

METHODS

The participants of this experimental study used the system two or three times a week for 10 weeks. We analyzed the changes in their body weight and body mass index (BMI) according to their respective usage of the system.

RESULTS

Participants' body weight and BMI decreased with respect to their individual usage of the system. Participants that used the system frequently for a longer time period improved significantly in their body weight and BMI.
