Abstract

OBJECTIVE: 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.

CONCLUSION: The experimental study showed that the body weight management system, HIMS-Diet, was effective in controlling people's body weight.
