Abstract

Obesity has become a serious issue in many countries with increasing prevalence every year. People with obesity has higher risk for several serious health complications and on a larger scale, this could bring negative implications for economic growth and human wellbeing of a nation. Many studies have been conducted to overcome this issue and some suggested that regular self weighing could promote weight loss and weight maintenance. Based on those findings, a body weight tracking system is made as an approach from technological side. The purpose of this system is to raise health awareness by using easy-to-use technology to monitor user weight from time to time. The system consists of a realtime database, a smartphone application, and a modified digital weight scale. The weight scale is tested to have more than 99% accuracy and can active for estimated 40 hours of usage, while the realtime database storage for this implementation is adequate for more than half a million users.
