Brief Summary

Obesity has become one of the global health problems. According to the World Health Organization, obesity not only affects an individual's physical health, but also increases the risk of multiple chronic diseases, cardiovascular and metabolic health problems. According to the health examination results of all hospital employees, there are many people with high body mass index. In order to increase employees' emphasis on health management, we held a weight loss competition to evaluate the effectiveness of So99 App. We hope to create a healthy workplace culture and reduce obesity-related risks through healthy eating, regular exercise and teamwork.
